4 Materials
10 Minutes

Got a dirty toilet, but you’re too lazy to clean up the mess?

No worries, I got you covered with this easy peasy toilet bomb.

You’ll need baking soda, citric acid, an essential oil of choice, and a mold to shape your bath bombs.
toilet cleaning bombs
STEP ONE: Add 1/2 cup of citric acid (or 8 tablespoons) into a bowl.

STEP TWO: Add 1 ½ cup baking soda (or 24 tablespoons).

STEP THREE: Add 10-20 drops of the essential oil of your choice. I chose bergamot for a fresh, clean scent.

STEP FOUR: Begin spraying water into mixture using a water bottle. Add this water slowly till it gets to a consistency where you can start to hold and form it.

STEP FIVE: Start forming your toilet cleaning bombs. You can roll it with your hands or use an ice cube tray to shape the concoction. Let the bombs harden for one hour.

STEP SIX: Drop the hardened cleaning bombs into your toilet and let the do the work!

Once you drop the bomb in it fizzes, cleans and freshens your toilet. Just let it sit for 10 minutes before you flush!

    12 tablespoons is 3/4 cup, not 1-1/2 cups. Which is it?
    • Hannah V
      on Jul 3, 2017

      It's 24 tablespoons, or 1 and 1/2 cups baking soda!
    • AngieZ
      on Jul 5, 2017

      She gave the right amounts in her post. 3/4 cups + 3/4 cups = 1 & 1/2 cups 12 T = 3/4 cups so 24 T = 1 & 1/2 cups
    • Ji*27318873

      Where did you see 12?!
    • AngieZ
      on Jul 24, 2017

      Half of 24 tablespoons equals 12 tablespoons. If 24 tablespoons equals 1 & 1/2 cups then 12 tablespoons equals 3/4 cup.

    Can the essential oil be omitted if you aren't looking for a scent, but just clean?
    • Dam2068431
      on Jul 5, 2017

      Yes the essential oil can be omitted without effecting the solution negatively.

    Hello "Fellow Long Islander!"

    Thanks for sharing -- I really have to make these. If I make a bunch and store them in an airtight container will they still hold their shape? Was also curious as to how many you made for the $15?

    Are these safe for a septic system?
    • Sue
      on Jul 6, 2017

      This is just a guess, but baking soda would reverse the enzyme action needed that takes care of the septic system?
  • Darlene

    can you store/keep these and if so what should you pu them in and how long can you keep them...thanks
    • C Van Houten
      on Jul 6, 2017

      They seem to contain ingredients as Bath Bombs, which I make quite often and I store them in those inexpensive plastic containers that Glad makes . I also save those little packets that come with medication and if it's summer, when the humidity is high, I throw one of the packets in the container to keep moisture away. I've kept bath bombs fresh for about a month. They might last longer, but usually, when I make a batch it's gone in a month or less.

    Where can Citric Acid be purchased other than Amazon?
    • Lee Ann Brickson
      on Jul 5, 2017

      Walmart, most large grocery stores in canning dept.
    • C Van Houten
      on Jul 6, 2017

      If you have a wine making store near you, you can buy it in larger quantities than Walmart, if you want to make a lot of bombs.

  • Katalin Paniagua
    on Jul 6, 2017

    I got the suggestion on how to clean a toilet but HOW DO YOU REMOVE THE STAIN THAT IS ALSO IN THE BOWL . The water does not come up to cover it up, so any cleaning hack would only work with elbow grease if I was able to do that.
    • Marros1960
      on Jul 6, 2017

      I purchased a pumice stone from Walmart that is for the stains in the toilet. We have hard water from our well so if we go away for a few weeks there is a ring. It was in the aisle with cleaning supplies.

    • Virginia
      on Jul 6, 2017

      I used a new pumice stone and DID NOT scrub scraped into the surface of the commode. It appears to have damaged the surface and the line remains. Can't seem to remove it . Have tried many other methods. If the surface is scratched, can it be fixed?

    • Katalin Paniagua
      on Jul 7, 2017

      Thank you for the idea. How does the comment from Virginia (Lafayette) fit in here. Can't afford to scratch it cause can't replace it (too costly) But I'm willing to try. Again, thank you
    • Esawyer

      Pour in about 2 cups of White vinegar & a couple of squeezes of Dawn dish soap swish it all around the inside of the toilet bowl let it sit for around 20-30 minutes, then finish scrubbing with the brush. This is very effective! You can even use just plain vinegar on any glass surface to remove lime & calcium deposits from hard water stains! Nearly no elbow grease needed LOL. Save a lot of money & great for the environment as well!

      I've used pumice stones on porcelain for 50 years and have yet to have it leave a mark or scratch on my toilets. Perhaps those who do have marks do not have true porcelain?
    • Katalin Paniagua

      Use a Mr. Clean Magic Eraser and Scouring powder. Or CLR with the magic eraser, but use gloves.

      I scratched my toilet with a pumice stone on my true porcelain toilet. It was wet and I did not push hard.
    • Donna Sheppard
      on Jul 22, 2017

      Yes, I also had the problem using a pumice stone on porcelain toilet years ago. I believe I used Zud to remove the dark marks. Zud is similar to powder cleansers but even better for rust, etc on porcelain.
    • Katalin Paniagua

    Is it citric acid or citrus acid ?
  • Stephanie Baldwin
    on Jul 18, 2017

    have you guys ever use ZEP acidic toilet bowl cleaner? i get it at lowes, it works for me, and for that subborn line that the water doesn't reach? a pumice stone will work on that but ZEP gets that also if you leave it sit overnight.
  • Kgo23897534
    on Jul 22, 2017

    I understand Katalin's question and I don't think anyone has addressed it. I have the same problem. Not the water line - but the entire bowl ABOVE the water line. Large area. Pumice is difficult and not very effective. Not an area that can be soaked. Any suggestions?
    • Patti Medrano-Hartman
      on Jul 24, 2017

      We have hard water that leaves terrible rings! I use 2pts bleach, 1pt water in a spray bottle and spray the bowl above the water line. I found that the bleach destroys most spray bottle mechanisms so i reuse a bottle from my bathroom cleaner which has bleach in it. For some reason this works better than just pouring bleach into the bowl, which i have tried. Although i do use Comet it doesn't work on our water rings. Pumice is too difficult and the results are so short lived.
    • Kgo23897534
      on Jul 24, 2017

      Thanks Patti. I will try that!
  • Kathleen McCarty
    on Jul 23, 2017

    Doesn't anyone use Comet anymore?
    • Peggy Owen-Barlow
      on Jul 23, 2017

      I use it all the time. I couldnt live without Comet
    • Catherine Hickman
      on Jul 24, 2017

      Not on toilets or anything made of porcelain. Comet is an abrasive and scratches the porcelain and ruins the toilets from being easy to be cleaned to being some ruined toilets. The label even says do not use on porcelain.
    • Susan Zoll
      on Jul 24, 2017

      I use a product called BarKeepers Friend. It's non-abrasive and that's all I use on my stainless steel sink. Works on toilets too
  • Kathie Rains

    Is this safe for use with septic tanks? I already avoid using any products with bleach.
    • Liz Phillips Turner
      on Jul 29, 2017

      I think it should be Okay. I have used KaBoom to clean a toilet with a chemical build up in it from a medication that my husband took for years and something in the water. The Kaboom sat for about 30 min and when I flushed the toilet the chemical build up disappeared. This home made recipe may do the same.
  • Bjm1725059
    on Jul 24, 2017

    Does anyone have the ingredients for the receipt that uses Dawn dishwasher detergent, Epson Salts, cleaning vinegar, etc.?? (
  • Cpl6791705
    on Jul 25, 2017

    I have this stain ring at water level in my toilet bowl (probably caused by letting cleaner remain in toilet to long - extra bathroom used infrequently) - I've tried everything I know - including, Coke (soft drink), baking soda, vinegar - scrubbing really hard, etc....nothing seems to remove this eternal blue ring. Can you suggest something?
    • Uki15374941
      on Jul 25, 2017

      Get a pumice stick. Works great, I get these too. I got mine at Home Depot, but you can get them a lot of places. About $2-3.
    • Blo25336310

      I cut small squares of drywall screen. The type that is used for sanding the drywall This removes hard water rings. I too have left the toilet bowl cleaner in toilet too long. The screen removes it. Just scrub with screen And ring is gone
    • Barbara Carlson

      I put denture tabs in my back of my toilet couple times a week. the tablets clean the ring around my toilet out, works good. I get them for a dollar a package.
    • Debbie Jones
      on Aug 23, 2017

      I also rely on drywall screen. We have well water and it is very hard it removes all the minerals from any porcelain service without any scratches makes it look beautiful and new.

      Be careful using denture tablets if you have a septic , they can break down the good bacteria in the septic.

      If you use witch hazel instead of water it works better.

    • Harleyontherun
      on Apr 26, 2019

      Alcohol is better as it evaporates some. Add your eo before you put your citric acid in. Mix well. Then add your citric acid and begin mixing it while you are adding it to your eo mixture so that eo doesn't activate your citric acid. Spray little amounts of rubbing alcohol while stiring. Stop and check your mixture. It should hold together when you squeeze it in your hand. Like damp sand. At this point put it in your mold. The one you did had to much liquid causing it to activate and cause it to over flow. If you can get on Pinterest and search how to make a bath bomb. You should find a lot to help you. Also try youtube so you can see how it looks in the sand state.

      Also when it is humid it is not a good day to make bath bombs unless you are in and air conditioned house with a dehumidifier next to you. Rainy days you may not get them to work. Moisture in the air will affect your bombs.

      Good luck,

      Careful with the Rain-X..... Your tub/shower floor can become super slick when you turn the water on to bathe or shower!
