I read about using "The Works" toilet bowl cleaner to remove rust from the tub and tried it. OMG..It works for real!!!! I paid $1.79 from Home Depot, squirted it all over (Use Gloves cuz it will burn your skin) took a sponge, wiped it all over and just left it soaking with the drain closed for about 1 hour. I'm so happy!!! From Nashville,Tn.

I tried 'nana6x's suggestion. It worked awesome! 'The Works' is at dollar tree and worked like a charm.

I was surprised at how well The Works works. Rust on my fiberglass tub just kinda disolved away after 10 minutes. I was also surprised at how useless CLR and bakingsoda/vinegar were. Just beware The Works smells strongly of rotten eggs buts it's worth it.

I too use The works it does good on my toilet., but the tub is harder. It turns the real dark rust to a orange. I had to use pumice stone as the scrubber. I am disabled and have to pay someone to do it.

The WORKS! Rust will honestly disappear almost instantly. Warning do not mix with bleach! The chemical reaction is toxic. Learned the hard way

Plastic bottles of Clorox that were left in a porcelain tub for a long period left rust stains in the tub. Why?

By Jarvi from Minneapolis, MN

Most likely the bleach caused the stains. Many times when the product, in this case bleach, is poured from the bottle there is a residue of bleach that will run down the outside of the bottle and collect on the bottom of the bottle. If the bottle is not wiped carefully the bleach will settle under the bottle and cause staining when placed on a surface.

Saturate the stains with hydrogen peroxide. Leave it on the stains, until the stains disappear, then rinse well with plain water.

Chlorine, the active chemical in bleach, is an oxidizer. Rust is oxidation. Chlorine causes rust to appear much faster than mere water based moisture.

How do I remove rust from my cast iron tub?

By Patricia D.

I have a white porcelain bathtub that was heavily stained with rust when rusty drain clearing cable was left spread in tub. Sprayed the tub, sprinkled Bar Keepers Friend on stain. Wet cloth and lightly scrubbed the tub. The rust disappeared 90% first application. Repeated day latter only traces of faint rust shows I am not sure how many times I can use BKF, their web site says remove after one minute.

How do you remove rust stains from a bathtub?

Rust Stains in the Bathtub

As far as I am concerned it depends on what your bathtub is made out of. For my metal tub I really like to use CLR in the yellow spray bottle, which I purchase at Walmart. But my tub surround is fiberglass and the CLR doesn't really do the trick for that.

For the tub surround I use something in a purple bottle with a green top. It is called Kabam or Kazoom, or something like that. If you look for the see through bright purple bottle with a green top you found it. I buy it at Walmart. If you have a big build up, it will take more than one application and some scrubbing. Once you actually get it cleaned, if you just spray it on and wait a minute you can wipe with a sponge and rinse.

Good Luck (03/29/2006)

Did you try Bleach? I would open a window and pour the Bleach wherever the rust is and let it sit. When it's done, hose it down with your shower. (03/29/2006)

There is no better product than Wink rust remover. It makes the rust disappear right before your eyes. I use it all the time and recommend it highly! (03/29/2006)

If it is enamel or porcelain, try using a pumice bar. I have an area around the sink overflow that gets rusty and the pumice bar takes it right off. (03/29/2006)

I use Clorox Cleanup. It's great for tubs and sinks and is non-abrasive. (03/30/2006)

Rust Stains in the Bathtub

I know this sounds a little crazy, but it works. It's called "The Works" toilet bowl cleaner. We have well water and it has a lot of iron in it. I just squirt The Works on it and let it sit for a minute and it wipes right out. I live in a mobile home so I have fiberglass sinks and tubs and it has never damaged them. Make sure it is the toilet bowl cleaner though. They make another product for soap scum and lime scale, but it doesn't work for rust. Good Luck! (03/30/2006)

If you live in the states there is a cleanser called ZUD, it is in a container like Comet Cleanser. We can't get it in Canada anymore, but my friend got me some in the states. Works really good and fast. (03/30/2006)

As Nana6x said, The Works, works very well. My conditions are like hers. I've left the stuff on over-night w/o problems.

Another idea, when you have the time. Use a fine/small grain of sandpaper; used it when I was out of the former and wasn't going into town anytime soon. The rust build up can be so thick but I've not seen any 'wearing' on the fiberglass tub. It does a fine job; also works on stainless steel kitchen sinks. (05/11/2009)

How do I remove rust stains from the bathtub?

By Kim from Hartford, CT


Rust Stains in the Bathtub

If this is a metal or cast iron tub, Bar Keeper's Friend (found near the Ajax, about $2) works well. (01/07/2010)

I have used a product called Whink. It works on just about anything but is pretty toxic. Can be found in most grocery stores. (01/08/2010)

I have rust stains on an old fiberglass tub. What type of vinegar do I use to remove the stains? Apple cider or white vinegar?

By Linda145 from AR


Rust Stains in the Bathtub

Not sure about vinegar, either one shouldn't hurt to try. If that doesn't work try a product called
"Iron Out" you can find it at stores like Lowe's or Home Depot. Good luck. (10/29/2009)

Rust Stains in the Bathtub

I am thoroughly amazed at how well The Works did on my tub. My husband just squirted some on a sponge and wiped the rust in one swipe. it created a very clean stripe down the wall. We have been scrubbing and scrubbing at this tub, trying to get the rust stains off the wall and tub itself. We tried Lime Away, CLR, and Kaboom. None of them worked, and you were worn out just trying. Thank you for the suggestion of The Works. I'm so glad I found this site. (10/31/2009)
