How do I take off hard water from my tub?

In Australia you'd use CLR calcium lime and rest remover, to remove the hard water marks. Good luck from down under

Try a product called CLR to remove the stains.

I used CLR for years and it works great! lately I have started to get concerned about my pipes however and switched to a less caustic cleaner. My home is a pretty old brick house so underground pipe trouble would be costly and using less toxic cleaners isn’t so bad if they work. Here is what I use

1 part dawn dish liquid

3 parts vinegar

for really tough stains you can heat the vinegar to give it a little extra power

pour the dawn in to a spray bottle then add your vinegar and swirl around to mix. You don’t want to shake this there will be suds everywhere!

Spray it on your stains and let let it sit for a while on tough stains. 30 min or so then use a scrub brush and brush away the stains. You can repeat if necessary. Follow up by using the mixture daily or every day and it should keep your problem at bay! I have a stone shower and if it works on that porous surface it should work great for you! Hope this helps out!

Norwex has a product that will help with this

YES. I WILL TRY IT!

I use a cleanser called Bar Keeper(wear gloves and rinse well it is toxic ) you can get at most hardware stores and a steel wool scrubby , if looking for a environmental friendly version of cleaner - vinegar and baking soda should work, hope this helps

I use Vinegar&Dawn mixed in equal parts for most everyday cleaning. But I have to say that Vinegar&Dawn won't get those set-in stains out of that tub. Try OdoBan, CLR Pro or BarKeeper's Friend (available at home improvement stores or online) and use Mr. Clean sponges and a stiff brush to scrub out dirt and stains. Stains that deep will require some muscle. After it's all clean, use a daily tub/shower cleaning spray after each use to keep it clean. Good luck!

I have the same issue with hard water and rust! As Erica Ray stated, Bar Keepers Friend works extremely well. It is a powder cleanser, similar to Comet. However it is much stronger and contains oxalic acid, you will definitely want to wear gloves. I start by making a paste using the Bar Keepers Friend and water. If your tub is made out of fiberglass, which is more porous than cast iron or porcelain, do not let sit very long (container recommends one minute). However, I have found with my cast iron and porcelain it works better if you allow to sit until almost dry (about 5 minutes). Slowly start adding water and using the scrubber side of a kitchen sponge. Continue to add water and use sponge/scrubber until all hard water residue is gone. Then give your tub a good final rinse. You will not have to use much “elbow grease” if you let the paste sit first. I use this method on my tubs, sinks, toilets, and the inside of my washing machine. I love it! Good luck!

PEROXIDE PEROXIDE PEROXIDE!!!! Just did it yesterday looks brand new

If I lived closer I'd come over to help. There are lots of products. Vinegar and warm water. Baking soda. Goo gone. Personally, I use Barkeeper's Friend in both the foam spray and powder cleanser. I use the foam spray on my shower stall, glass sliding door, and also my glass top stove. I use powder cleanser on my stainless steel sink. It shines! Works great for me. I think this will work well for your situation. It may take several attempts, but don't give up. Best of luck.

Like several people here, I've used CLR for years and love it. To take it up a notch I've begun using my cordless drill with a scrub brush attachment after applying the CLR. (Very inexpensive on Amazon.) My tub/shower wall isn't only clean but the power scrubbing makes it shine just as glossy as new.

Check out this site. I think you will be impressed.

My go to for cleaning the tub is always Barkeepers Friend. I've used both liquid and powder. It it great!

I had the same problem except a textured bottom tub. I read somewhere to use non-fuming oven cleaner (you can find a cheap one at Walmart) spray and leave it sit overnight. The next day scour with Soft Scrub or Super Clean and a scouring sponge. Rinse and then remove remaining with one of those Mr. Clean white sponges. It took away grime that had been there over 14 years.

Barkeeper's Friend and a very, very fine sandpaper will do it.

If you are renting for that long, you should be able to have your landlord replace the tub at no cost to you. Review your lease and mention that if you moved out, the landlord would most likely have to pay for replacement anyway.

First you need to get that lime deposits and soap scum off..... I would do the Easy Off Fume Free Oven cleaner in the blue can and give it a good spray. Open the window and put the exhaust fan on. Wear kitchen rubber gloves and get a white magic eraser. https://www.youtube.com/watch?v=L10jCtHCcmY

Then follow-up with Gel Gloss that will shine the tub and prevent scum from sticking... https://www.amazon.com/s/ref=nb_sb_ss_c_1_9?url=search-alias%3Daps&field-keywords=gel+gloss+cleaner+and+polish&sprefix=Gel+Gloss%2Caps%2C277&crid=FMDXIA6NI7GW I would put some of those abrasive strips on the bottom afterwards or a bath mat to prevent slips.
