If you don't want to take the time and the expense to remove and replace your shower or bathtub caulking that is currently moldy, then this is a great way to remove the mold and mold stains that is very affordable and easy! Plus, it works amazing!
So, if you have a bathtub with caulk that looks like this, follow along!
You'll need cotton balls, gloves, water, and bleach. Eye protection and a ventilation mask also recommended.
Mix water and bleach together in a small dish, using only a little bleach. Open the window, turn on the fan, and wear gloves!

Dip a cotton ball into the bleach water and then apply the wet cotton ball directly to the caulking around your tub.
If you have moldy spots in the vertical caulking of your tub, stretch out the cotton balls a bit first before dipping them in the bleach water. Start with the highest part and then work your way down as the liquid dripping down will cause the ones below it to fall.
Let the cotton balls stay on the caulking for about 2 hours. Remove one and see if the mold is gone. If not, wait another hour.

If looks good, remove the cotton balls and dispose them in the trash.

You should now have beautiful caulking!

    Would this work on grout on a tile floor
    • Ashley Gary
      on Jul 23, 2017

      I would imagine it'd be perfect on grout, but I'd test first in an inconspicuous spot first to make sure the bleach doesn't have any effect on your grout color since caulk is typically white or clear to begin with and grout is not.
    • Dana
      on Jul 23, 2017

      for mould yes. Not for dirt in between. For that go to the flooring specialist, they have some products for that. Check your local hardware shops.
    • Dana Miller Ford

      Worked great on the walls but not on the floor at all.
    • Karen Street
      on Jul 23, 2017

      Here is my experience, bleach goes black in applied areas where light is not constant, ie: rooms with no windows or blocked by heavy curtains with no light. It looks worse than mold and removal of caulk becomes necessary to correct the black stain. Sunlight and light activate bleach to brighten, like cloth diapers on a clothesline.

      I just pour bleach on any spots of mold I see and it clears them up . I get it at the bottom of
      the walk in shower
  • Pauliegirl1

    Doesn't the mold come back? Eventually?? I would think you have to get to the 'core' of the mold??

    • Jennifer
      on Jul 23, 2017

      I wondered that, too. I was told by a disaster cleaning company, and have seen on shows that do restorations, (Mike Holmes for one)
      that bleach and other things just remove the color. They said it has to be removed, or it will come back. I'm thinking you are right about this. (but I am not a pro)
    • Alliecat
      on Jul 23, 2017

      I think the cause of the mold is superficial--it's due to the moisture in the bathroom. Maybe cracking the window after a steamy shower would help... or just cleaning it every so often as they've done here
    • Elaine
      on Jul 23, 2017

      Yes, mold will return as it loves moisture - the best bet is maintenance! By that, I mean never letting the mold develop to that extent; keeping on top of jobs in a house is a lot easier than letting them become more laborous. After every shower, I use a squeegee on the glass shower door (no streaks!!) and on the walls then I wipe everything down with the bath towel I just used on myself. This extra bit of effort has resulted in no mold, so far.
    • Gidget
      on Jul 23, 2017

      After the bleach, and all is dry, wipe the surface with white vinegar. Vinegar doesn't remove mold, but it retards its regrowth. The vinegar smell goes away quickly. (old boat trick).
    • Katelyn Fagan
      on Jul 24, 2017

      It will likely come back eventually. The best thing is to try and keep your shower as dry as possible in the meantime. But, I'm hoping this will keep my caulking white for at least a year. :)
    • Kim
      on Jan 21, 2018

      Vinegar kills 87% of mold it is sprayed on. So if you were to spray it every day and kill 87% more each day it will be gone.
      1st day 87%
      2nd day 87% of the13% left from the day before.
      In my basement some mold started and I used the vinegar and it is all gone. I still spray when I think of it to keep it gone.

    • Jennifer
      on Jul 23, 2017

      In the comments below people suggested peroxide or Greased Lightning. I have both, and will experiment.
    • Wyldecent
      on Jul 23, 2017

      You could try hydrogen peroxide. Or new caulk.
    • Elaine
      on Jul 23, 2017

      Hydrogen peroxide should work too.
    • Patti
      on Jul 23, 2017

      H2O2 (hydrogen peroxide). 3% comes in a brown plastic bottle at the drug store, Target, Walmart, etc. where you would find Epsom salts, rubbing alcohol, et al.
    • Ann stewart

      KaBoom is a great product for this and you don't have to use the cotton balls.

    What a great idea ,does it also all work on painted walls ? Some of my walls in my kitchen has streaks from steaming it doesnt seem to get the scum off of them.
    • Elaine
      on Jul 23, 2017

      No, don't use this idea on painted walls as the bleach will affect the paint color!
    • Elizabeth
      on Jul 23, 2017

      This is tedious and doesn't take care of the whole problem. You still have moldy, discolored areas on the upper tiles. There are commercial sprays (yes you have to pay a little) that will remove that dangerous mold and mildew.

    I have had my tub and walls "refinished". Would this process be safe for them?
  • GBay Girl
    on Jul 23, 2017

    Anyone know if this can be used (re bleach) if the mould is in a Bathfitters' tub? I don't know if bleach can be used in the acrylic. If it can safely be used, I'm going out to get some cottonballs and get this project started. Thanks.

      on Jul 23, 2017

      I accomplished this with 50/50 bleach and water in a spray bottle. I just do it quickly with a mask on and get out. I let the bleach odor dissipate before I go back and wipe it down. If you have asthma or respiratory problems, I would advise you not to do this.
    • GBay Girl
      on Jul 24, 2017

      I have asthma so I really appreciate this insight. Re calling BathFitters - I have several times without any response.
    • Dpbeee2

      get a huge fan and suck the air out of the bathroom.................
    • Suz27841008
      on Jul 23, 2017

      Agree with fan, but face it into the bathroom, not out. When you do the cotton balls, do it quickly, and get out. If it is not done perfectly the first time, you can do it again, but you can wait until the bleach smell is aired out. I use a bleach, water, liquid dish soap in a spray bottle on my tub and tile grout. Sometimes a commercial type.


    • Stephanie Dougherty

    I didn't think of using Borax...I've used bleach on the grout in my bath and it did NOT work. At the time I just wanted to get rid of all the 'black' in the grout. Could you use your mixture in a spray bottle???
    • Angie Burk
      on Aug 13, 2017

      Bleach does not kill the mold spores, it only bleaches the color (black) away. There is a very good mold killer and stain remover called "x14" I get it at my local hardware store.

    • Mina Scousin
      on Jan 21, 2018

      Yes, but it comes with a catch. Bleach labels will warn you that chlorine bleach will only be effective on a “hard, non-porous surface.’’ This basically means that chlorine bleach is not made to “soak in.” Therefore, its disinfecting properties are limited to a hard surface like tile or glass. So here’s the problem: To ensure survival, mold spores spread its roots (Mycelia) deep into a porous surface. Mold remediation requires a cleaner to reach deep down into wood and other porous building materials to remove or "pull out" the roots. The properties of bleach prevent it from soaking into these materials. The surface mold looks gone (it's bleached white) but the internal mold always remains to grow back.

    how do you get rid of mold/mildew on a tiled ceiling?
    • Brenda Meyers
      on Jul 24, 2017

      Tilex mold and mildew will do the same as your clorox and cotton balls and is much easier. Just spray on and return later and see that mold has disappeared!!!
    • Mcc21382458
      on Jul 24, 2017

      problem is spraying product on the ceiling turns into tilex in your eyes and on your face...gravity doesn't keep it on.
    • Susan
      on Jul 25, 2017

      put the bleach or tilex on a flat bottom mop, like swiffer, and apply to ceiling. With a little scrubbing, I think this would work. Like mopping upside down. Just don't use so much that it drips on you.
    • Rebecca
      on Jul 25, 2017

      I used tilex spray with great results. Just be sure to not over spray, protect your floor and any other objects close by. I used a step stool placed off to one side. I could still reach the stain but get off of and out of the way quickly, wore gloves and eye protection and clothes that I didn't care about. I sprayed left the room and came back an hour later to check the stain. The stain took about three sprayings but was pretty bad (from a roof leak)and had been there a long time. Ceiling looks great!

    • Kyp Purifoy
      on Jul 26, 2017

      I used a swiffer mop with a dry cloth sprayed with bleach to wipe down the walls and ceiling. However, the Tilex spray wouldn't smell as strong as the bleach. I ended up with too much bleach in my lungs, since I didn't wear a mask.
    • Marcia
      on Jan 21, 2018

      For years I wiped down the shower walls and edge of the tub with a dry towel and I rarely got any mold. If I got any, mostly in a corner or under the tub spout, Tile did the trick or clorox clean-up. Both worked well.
    • Mary Ellen
      on Jan 21, 2018

    • Millie
      on Jan 21, 2018

      I have never heard of pink mildew. Could it be your mildew has turned color because of buildup on it? You could take an old toothbrush and scrub it to see if it calmed off, but the bleach should do the work for you. Don't forget to ventilate, very important.
    • Janine Wereley Putzer
      on Jan 21, 2018

      It should. Pink even easier to remove. I get it on my shower curtain liner occasionally and I sprayed on diluted bleach and it's gone.
      Also, it should be listed above, but I believe a 10% solution works fine.
    • Michelle
      on Jan 21, 2018

      I had white wash cloths that would get pink mildew stains after 3 days of use. Washing would not remove the stains. I would put them in bleach water for a day. They got pristine white and the pink mildew stains did not return. I also use bleach to clean the mildew that starts in my shower. This works better than buying cleaning supplies in the store.

      Just so no one panics over pink mold, which is very common. We have it here too on our shower liner. I toss it in the washer with bleach once a month with cleaning rags etc.

      Everyone is aware of black mold that is very dangerous and toxic, causing harmful effects on the health of humans. ... ➺ Pink mold is actually a bacteria and not a fungi. This bacteria, scientifically called Serratia marcescens, is most commonly found in bathrooms.
    • Lynda Miller
      on Jan 21, 2018

      Be careful with the bleach! Not recommended for grout on expensive tiles and it will definitely shorten the time between resealing the tile.

    • RaNae

      Are you sure the pink is actually mildew? I continually had pink colored deposits but they disappeared when I changed to iron remover softener salt.
    • VickiC
      on Jan 21, 2018

      'Pink mold is actually not a fungus, pink colored mold is caused by a bacterium called “Serratia Marcescens.” This bacterium contains a type of mold, and it thrives in moist, wet environments.
      It is suspected that pink bathroom mold is not as dangerous as black mold.
      Also, this mold growth can be prevented by avoiding soap buildup on the shower walls and floors. It is suspected that pink mold actually feeds on soap residue, so allowing the residue to sit on walls and floor of the shower may promote additional growth.'

      I cleaned homes for years,I got all my people to use liquid soap. I got tired of scrubbing soap off. I used tilex for years until I broke out in hives, and eventually had to quit cleaning jobs due to fibromyalgia. Was it toxic overload? 🤔probably,in my case.

      @Cheryl Glodowski. Yes there is still some mold showing in the last picture as the bleach did not remove all of it. But if you look at the first picture and the last picture there is definitely a difference.

      Over time, strong chlorine can damage the surface of shower walls and tubs, so i wouldnt spray it on. Manufacturers recommend solutions of Dawn, white vinegar, and water for spray cleaning. Using the cotton balls with bleach and controlling drips sounds like a good way to attack the caulk mold. I'm going to try it!

  • Ellen Keyes
    on Oct 2, 2018

    Have you used the idea of a paste of baking soda and bleach? The baking soda is just a conveyor for the bleach so the cotton balls may stick well to the caulk and you can paint the paste on the vertical areas. It worked really well and lasted several weeks. I have noticed that those sprays you buy in stores don't even last two days.

      Way too strong using straight bleach. You could burn skin and nostrils.

      A little bleach in water is more than effective even if only 5 drops in a gallon!

      So just give a splash of bleach in your mix.

    • Beth
      on Oct 2, 2018

      Viv, I don't know of anything that will kill mold other than bleach. However, the hint here was to use it if you wanted to avoid taking out the old, moldy caulking, so your alternative is to go ahead and do that and re-caulk. Otherwise, remove the birds from the house while you use the bleach and for the day after. Get a good exhaust fan, and run it when you bathe and for a while after, and you shouldn't have mold build-up.

    Isn't cotton coil, like they use at the hair salon, non-absorbent? I mean, the whole point of it there is to keep the solution from getting on your skin, so if you use it here in the bathroom, does it really soak up the bleach solution?

      You soak the rope in bleach and then lay it on the grout around the tub. I don't recall how long you leave it whether it's a couple of hours or overnight. If anyone else saved that hint maybe they can reply.

    Why not just cut it all out, use the bleach to clean up residue and recaulk around the tub after it’s thoroughly dry?

    • Kathy
      on Oct 8, 2018

      If it's your only bathroom/tub/shower, the recommended dry/wait time after cleaning and recaulking, and before using is 2-3 days. You have to initiate the cleaning, wait 24 to 48 for that to dry befire caulking. Then wait another 24+ hours for caulk to cure properly. Can you go that long without a shower?

    • Anna

  • Gabrielle Falk
    on Oct 24, 2018

    Bleach does not kill mould - at all. It bleaches ie whitens, the grouting/caulking, but does not kill the mould. I know from experience. That's why the mould returns. There are other ways - vinegar is not terribly successful. Best to go to Dr. Google, and see what is in the offing. I tried cleaning the bathroom ceiling with bleach for small mould spots (the window is always open and we use the extractor fan), but the mould always returned. Had a painter come in and he applied some foul smelling undercoat on the ceiling, and then used a mould retardant paint. He said to me, even tho' I already knew, that bleach does not work. Just colours. Best to get rid of the caulking - I know a yuk job to re-do, remove all the residue, and give the bath/tiled wall a good scrub. What I've done in the past is used my hair dryer to dry wet spots like the bath surround, as mould does not like heat. In re-caulking make sure that there are no little gaps. Is the grouting on the tiles keeping the water out? Good luck.

      Bleach kills mold and is very effective if used on hard non porous surface. In this case it would not. Bleach does kill mold but not on everything.

    • Karen Daniels
      on Nov 4, 2018

      I did this exact method 2 1/2 years ago after moving into our new home. It’s never come back. If mold is coming back it is due to poor ventilation most likely. Always use an exhaust fan and leave the shower curtain or shower doors open a smidge on both sides to allow good ventilation. Hope this helps :D

      After you go to all this trouble. Get you some tea tree oil from the drug store and Qtips and spread over all you cleaned. It will kill the mold and it will not cone back. I do mine once a month with two of us showering everyday.

      You can get tea tree oil at the drugstore. Good luck.

      I am a cosmetologist and you can purchase cotton in one long strand at any beauty supply store. Some stores may sell only to licensed cosmetologist so just check first. You can even ask at any beauty salon if they would sell you some. Then all you need to do is tear off at your desired length. That would be so much easier to use than all those cotton balls. It's not expensive and quite absorbent

      I use a Dawn dish detergent (plain or oxi kind), borax, vinegar, and water cleaner recipe. No scrubbing, kills mold, and definitely doesn’t come back!! I only use it every few months!! In between I use recipe I make with vinegar, water, and essential oils (lemon, orange, whatever I’m in the mood for making). I make the kids and my husband spray the shower and tub lightly after each use with it also!! :) I’m allergic to bleach so I have to be careful using it and inhaling it. Plus, I hate getting it on my clothes from splashes. ;)

      Do you mean SHEET ROCK? It's the cardboard covered white gypsum used on walls....sometimes called "wakeboard". If so, the answer is NO. Sheet rock should be painted & never put water on it. It will mold, mildew & fall apart. Never heard of "sheep rock".

      I would like to share with you my experience with cleaning up mold. Bleach will take away the color but not kill it. Instead mix white vinegar and hydrogen peroxide in equal amounts and they will kill the nasty stuff. I love the idea of the cotton balls though.

      I learned this when my daughter lives in a mold infested apartment. Bleach can actually encourage the mold to come back and grow worse.

      When I had flooding, the company sprayed the affected damp sheet rock with a strong mixture of bleach and water to get rid of the mold and possibility of mold growing. I would not use the cotton ball method on sheet rock as that would soak the sheet rock and perhaps make it disintegrate. Spray it well and then let dry or place a fan nearby to circulate the air dry the mixture that has been applied as quickly as possible.

      I was going to say the same thing this way you wouldn't have to waste all those cotton balls. Just keep a small bottle just for bleach and water beside your tub and spray away 2-3 time a week leave the window open and don't use too much bleach. I have a bath fitter and everything is lifetime except the caulk, of course. Every couple of days I spray the caulk and when I need to I will replace the caulk in which they do not cover any way.

      I think bleach is bleach I have never noticed any difference in store brands and higher priced bleach. Check the ingredients against each other in the store, and since it only takes a little bit, just buy a small container of the one you want. Clorox is the only one I can remember the name of. It may or may not be the best.

      on May 5, 2019

      Baking soda, dawn and vinegar, then give it a really good rinse (because over time vinegar can corrode if not rinsed off well!) Best mix and not only are you just bleaching it white, but it also corrodes it over time to where you will have to replace the caulking anyways.

    • Bleach does not kill the mold spores or mold roots it only discolors it and makes it somewhat white again making people think it’s gone. But it’s a matter of time before it grows again. Use a product named “Concrobium Mold Control”. I get it at The Home Depot in a spray bottle. It’s about $9-10 for a 32 oz spray bottle. I hope that helps you

      From microbiology days, pink = staph aureus. Lysol, bleach or vinegar and soap. Have also used hydrogen peroxide (H2O2)in the bathroom as it does wonderful things like helping a slow drain run faster. When it bubbles,that is a sign that is is working plus it breaks down into water (H2O) as its extra hydrogen molecules (H) glom onto the gunk.

      They say bleach doesn’t actually kill mold. I read up on what actually kills mold and chose a more natural combo of white vinegar, peroxide and Thieves cleaner. This was very affective in killing the black mold and keeping it away, while not using anything harsh, because there is a baby in our home. Like the person above said, “kills” does also work if you want a harsher chemical to kill it.

I was i little worried the room would smell like vinegar but it didnt. The bad odor is absorbed into bread by vinegar. Also, place softner dryer sheets inside of hamper. Also lol, the shoes he wears that day, put some alcohol in a small spray bottle, spray the inside of those shoes (you dont have to saturate) just 3-4 sprays and this is the most important part... LEAVE THEM OUTSIDE OVER NIGHT.

Sprinkle the carpet with a gud brand of carpet powder. Then get sum gud smelling plug-ins😊. Boys will be boys and smell like them too sadly😩.

      Have kid do his laundry! ;-)


      I’ve raised 5 boys. They stink. Their rooms stink. Their sports pads stink.


      Heres’s what I required:

      1) all dirty clothes go into hamper ASAP. Hamper has lid. Close lid.

      2) make bed daily

      3) wash bedding weekly

      do hamper laundry every time hamper is full

      4) no food leavings (pizza crust ends, etc) nor dirty dishes left in room ever.

      5) shower before going to bed

      6) shower after sports practice or game

      7) ALL sports gear is washed ASAP

      8) sports pads get wiped down with vinegar based cleaner weekly.


      This reduced stinkage. It also kept the sports equipment in healthy shape & could be passed on to the next kid. Plus, it kept the value of my home from dropping they the basement. 🤪

      One big thing is to use liquid Lysol to sanitize laundry at least once a week, and toss his shoes with a load of towels in on the gentle cycle with the liquid Lysol. (Washing towels every other time or two will help your linens or bathroom to be fresher too. (Use a weak liquid Lysol solution in place of commercial rug cleaning solution in your rug shampooer if you clean the mattress- do while he's staying over at a friend's, & have him crash on the couch for another night or two, to allow for drying time)


      I've seen that there is actual Lysol Laundry Sanitizer on Amazon, but I choose to pick up my preferred scent when I hit a Wal-Mart. :)

      I haven’t seen one answer that makes sense. Make your teenage boys clean their rooms. If they don’t take away Privileges. Like TV, computer time, car privileges if any of them drive. etc.


      If they don’t do it, follow through with what you told them and when they complain tell them you are the parent, it’s your house, you pay the bills and if they don’t like it charge enough rent to pay for a housekeeper.


      Additional advise, when they ask you to do something for them, and they aren’t respecting you, tell them no when they ask you for a ride or privledge. Say: You don’t feel like it because, they don’t do what you ask them to do.


      It’s called tough love!!!!

      Never let your kids use you. Make them meet your expectations as long as you are reasonable.

      Use Dawn dish soap right on the stain and scrub the stain between your hands! Throw in washer and it should be gone! If it's a big stain you might need to do it again!!!

      I use over cleaner!!!! Easy off or the cheap brands. It’s been a clothes saver it even worked on vehicle black grease! Doesn’t ruin your clothes!

      For most grease stains I sprinkle talcum powder on the stain and rub it in with my fingers. Let it stay on for 10 minutes or more, then brush off powder and wash. Any powder will work, anlso baking soda.

      Dawn dishsoap

      Spray with shout and let set for 4 hours before washing. You will need to treat more than once, so don’t set the stain in by drying. Let the garment air dry and throw it in with the next batch of like colors after retreating.


      Additionally, don’t let liquid shout air dry. It is capable of taking some color out of died fabrics. Only the stick is formulated to stay on fabric for several days without any problem.

      Soak it in dawn dish soap before you wash it if it’s dried in it might not work

      Spray it with a grease cleaner like 409, or FANTASTIC. Any kind of grease cleaner should work. Let it set a couple of hours, then wash as normal.

      Order some lestoil online. You can't get it in the stores anymore. It will even take out oily stain that has been through the dryer. Just apply directly to the stain and was as usual.

      Dawn dish soap works very well on all grease stains. Also regular coke.

    • Thanks or making the info so clear.

    Could u just use a spray bottle with bleach and water? I think it would work too then come back 10 mins later and rinse.

      I think there will be streak marks where the bleach drips down the shower lining. I also think the killing of the mold will be less effective.

      They make bleach gel that would be even handier, and it would stick better, use a stop to spread it to cover the problem areas.

      Thats the way I did it. I would spray water and bleach every other week or so and rinse. Never had a black mold problem or dirty caulking. It cleans all the germs.

    I have mold that started on my attic roof I haven’t found the leak yet on the roof and it’s not bad but a couple things had a little bit a water on them but it made the whole one side of the attic moldy would this work for that on the wood ?

    • Lisa Witt-Widner

      make a combination of tsp and bleach, and soak everything like crazy. Hydrogen peroxide has also been known to be highly effective

    • Lisa Ann Browning

      Just make sure you have a mask, eye protection and gloves to neutralize the mold. Don’t scrape it, scraping dried mold or moldy areas will cause it to go airborne. Then treat it with the neutralizer of the bleach and water mixture.

      I would spray with a mixture of Thyme oil and water, or else spray with Benefect, a cleanser with Thyme oil in it. You should be careful using bleach, use a face mask for sure either way, as mold spores can be airborne and inhaling those buggers are seriously bad for your health.

      Spraying anything on them puts them into the air. I’d call a mold remediation company for a free estimate. Mold can grow on your shingles and spores spread down into the attic. It can be from condensation in the insulation. A small drip on a pipe. A chewed hole from a rodent ...... get a feee professional estimate or a couple free ones then choose your plan of attack. Educate yourself! This could even be an insurance claim.

    Can't we also put the mixture in a spray bottle & spray it on & let it sit a few seconds or so, then rinse. Repeat as necessary.?

      I use the extra strength, thick Clorox, put it into a dish soap bottle and squirt my shower, toilet bowl, kitchen sink, you name it! Sticks on better than mixed with water.

      The cotton balls keep it contained in the mold area. Spraying the liquid is not going to stay exactly where you what it to do its job.
