We have a well and our toilet, bathtub, sink, and washer all get stains. I tried everything and finally I went to a Mercantile Store, they have items that others don't. I asked the owner about the stains and she said she uses The Works, it's in a white bottle. It works great.

Be sure to rinse the bathtub out really good. I have used the green bottle, but it doesn't work for what I need it for.

I tried everything to clean well water rust stains, also. Then I decided to try the dollar store version of the Mr. Clean erasers and the Kaboom Foam-tastic. The erasers will do the job by themselves, but it takes a lot of work. Just spray on the Kaboom and let it sit for about 10 minutes. Then clean with the erasers. Your tub should be rid of the stains. If it's really bad like mine was it may take a few tries. Good luck!

This may be more classified as a warning to those of us with fiberglass tubs, but here goes. Be very careful with the toilet bowl cleaners, CLR, and anything that reads that it could etch your toilet bowl, as you will remove the finish a little at a time. The vinegar and baking soda will take a little time if it is bad when you start, but it won't harm the finish. After you get most of it off, you may use Zud and when all is gone, then use marine polish.


This recommendation came from the repair person who factory fixed my tub after it was put into our new house 16 years ago. My tub is still shiny. All fiberglass tubs and older tubs aren't made the same. You may also want to go to a tub and tile shop and ask what to use to clean your type of tub and then maybe you'd get something different to share with all of us. Happy cleaning.

We have hard water where I live. My bathtub is white, but for some reason, it is getting grey stains on it. I have tried every product that I can think of, none of them has helped remove the stain. I filled the bathtub and put a full bottle of bleach (4 litres) in the water hoping this would help, and left it overnight. It did nothing. Is there anyone who could please help me. Thanking you in advance.

Lysol Toilet Bowl cleaner works great in tubs and showers as long as its not a stone one. Squirt it on and use a flat scrub brush to spread and cover entire surface. If you do not cover entire surface you will have clean streaks. Let sit for 30 minutes and rinse off with warm water. No scrubbing involved at all. I have been cleaning homes for 25 plus years and this secret ingredient works wonders. Owners are amazed and say they haven't seen it that shiny clean in years.

the only thing you can do is what I'm going right this minute is. sitting on my sons kiddie stool and using a pie slicer or paint scraper or a box cutter to literally scrape it off. tilex kaboom none of those products will penetrate. I found this out when I used my fingernail to see. I took my shower doors off I have a mask on because its a chalk white powder that comes off and it working very good just make sure to turn the pie slicer backwards I have a square one works very well.

good luck

I am building a house. My plumber left well water in the bathtub. It has been 6 months now because I am building slowly,due to funds. Will the water stain the bathtub, and will it be difficult to clean?

CLR is what will remove, calcium, lime and RUST from the tub. Depending on how long the rust has been there, it may take a few soakings to remove, but it definitely works.

Cleaning Well Water Stains From Tub

Have you ever heard of Watkins products? The company has been around for over 130 years, and many people used to purchase Watkins products from door-to-door salesmen years ago. I am an independent Watkins associate now, and I have been using their products and learning about what they can do. Yesterday I used their toilet bowl cleaner for a basement toilet that has terrible hard-water stains and hard-to-clean areas. Anyway, squirt it on, wait 10 minutes, and like magic it just slid off. Their also carry a Tub and Tile cleaner and another items, Bathroom Cleaner Plus, and they both sound like they could work for your problem. Go to (06/30/2004)

I too have the same problem. I called the manufacturer of the tub, American Standard, and they recommended a product called ZUD, and KRC-7. I found ZUD at Ace hardware, and it helped a great deal, but not completely. I had painted the tub with Klinks and it looked beautiful for about three months, and then the stain returned. I contacted Klinks, and they said to be sure and use distilled water with their product, which I did not know at the time of application. Hope we can get some more feedback on this problem.

When living in South Dakota a lot of people living out of town had this problem. The recommended way to clean well stains out of a tub or sink is as follows:

Clean the tub or sink well with your usual cleaner, rinse with water and let it dry completely. Pour straight white vinegar into a spray bottle and liberally spray on to affected areas. Let set for at least ten minutes. Rinse off and spray the area with a product called C.L.R. You can buy it in your grocery store with the cleaning products. Be sure to have the area well ventilated. (CLR stands for calcium, lime, and rust remover.) Let stand ten or twenty minutes, rinse and respray until all stains are gone. Use cold water to rinse and never touch the product with your bare hands. After removing the build-up, use at least once a week. Many of the people I talked to said this worked every time.

I don't know if this will work. Fill your tub a little above where the stains end. Fill the tub with denture cleaning tablets, 50 or so. You can buy them cheaply if you get the store brand. Let sit overnight. After it sits all night, try scrubbing with a rough-sided sponge. Good luck. (07/01/2004)

Cleaning Well Water Stains From Tub

If the bath is fibreglass the stain may be in the fabric of the bath itself and I don't know what to suggest. If it is a ceramic bath the cheapest, easiest, chemical free way to get rid of surface mineral deposits is to "sand" them off with very fine sandpaper. In Australia it is black, called "wet and dry" sandpaper. As the name suggests it can be used wet or you can use it with cleaning products if you wish. This does not damage the surface of a ceramic bath and you can, in fact may need to, rub quite hard. You can also use this method in toilet bowls for the "ring". I have a feeling that bleach only removes the colour from the mineral deposit so it reappears very quickly. Wet and dry sandpaper actually removes the deposit. I don't use any chemicals in the toilet because it disrupts the natural breakdown in our septic systems. This method is more effective, healthier, (as you don't have to inhale fumes), and more environmentally friendly.

We have well water here too! I bought "The Works" toilet cleaner and when you spray it on, the stain just melts right off! No elbow grease involved. The best part is, Wal-mart sells it for .98! I have also been told that SOS pads work, but they require a lot of elbow grease. Hope this helps!

Try this. I have a well, and the yellowing in my tub drove me crazy. I use Snobol toilet bowl cleaner. It's the only thing I have found which works well. I use it full strength. Put some on a sponge, and wipe it on the entire yellowed area, then rinse the area completely. Do not leave it on the surface very long.

Important: It WILL ETCH the fixtures, so you must be careful NOT to get it on the faucet, handles, etc. My tub was new 8 years ago, and so far the Snobol has not etched the tub at all, but I am extremely careful not to leave it on too long.

I also have found another product which helps with the lime scale, and hard water stains on the fixtures. It is Comet Bathroom Cleaner. It is a spray cleaner. Do not use Lime Away. That will ruin the finish on your tub. I had that experience. Good luck! (07/05/2004)

I have had all types of well water stains. I use a product called Rust Stain Remover made by Whink. It's great, all you do is pour on to the area that's stained and it's gone. When using it in the toilet take some water out below the stain line and pour on. You can get it at Wal-Mart, Target, Ace Hardware, and K-mart. (11/09/2004)

I live in TX and the local water stains. I bought a product they advertise on TV (one of those Oh God Nothing Works moments) and had wonderful luck. I tried the Restore4 product designed for tubs and sinks. It worked wonders. (11/09/2004)

I am new to well water and took my mother-in-law's advice that's worked well for over 30 years- Bar Keepers Friend.
I get it at Walk-mart for under 2.00 and it's a big container. Looks like Comet containers, but taller. I use it on sink, tub, floor, even toilet! Gets rust stains right off with hardly any scrubbing. (08/29/2006)

Also, after getting the stains off, I use Lemon Oil as a final wipe. It helps keep the stains from sticking in the first place, while it keeps the entire room smelling lemon fresh. (02/20/2007)

Try a pumice stone. I tried it on my toilet stains from hard well water and it works. I purchased mine in the cosmetic dept. it is used on rough feet, but mine took all the hard water stains off. (06/04/2007)

Try Lysol thick blue toilet bowl cleaner. I had terrible sulfuric acid stains in my tub from a drain opener product and it took those out. Test on your tub first to make sure it wont hurt the finish. Good luck! (11/17/2007)

I found this forum while trying to find help for my own well water rust stains. Thanks to Jessica, I now have a very white bath tub. The Bar Keepers Friend did the trick very easily. I had tried The Works, Comet, Iron Out, and the list goes on and on.
Thanks! (03/07/2008)

I use Zep acidic toilet bowl cleaner it removes the yellow on tubs and toilets with little scrubbing involved. Pour some in tub and spread around using rubber gloves, remember it is acidic and wait 5 minutes, then rinse off. (04/06/2008)

Cleaning Well Water Stains From Tub

I have well water and let me tell you I have tried "everything" possible. I have found that a pumice stone works, but it is a lot of work and the stains come back later. The only thing I have found to work is a cleaner called Resolution Natural Tub and Tile bath cleaner. It is earth friendly approved and all natural, too.

Normally it costs $2.50 for a 32oz bottle, when on sale it is only $1.44 and sometimes Menards has a mail in rebate and it works out to be free. I don't know if it is for sale anywhere else, but it is always at Menards. I am serious, this stuff is magical. I use it as an after shower spray and our tub is as clean as can be. Way better than automatic shower cleaner and way cheaper. Try it!

Charlie Soap all purpose cleaner works for me. Just spray on the stain and wait about two minutes and wipe off with a wet sponge. It really works better than all the other cleaners on the market. (06/21/2010)
