What's the best way to remove rust stains from a bath tub? I think its porcelain.?

Question

It has built up rust on it too.

Answer 1

Bleach will not remove rust stains -- bleach is an oxidizing agent, and rust is fully oxidized iron. Vinegar, however, may, as vinegar contains acetic acid and iron acetate is soluble. So try scrubbing with vinegar. There are also proprietary products available intended to do the job; find them at a hardware store if the vinegar trick doesn't work.

Answer 2

Periodically I fill my tub with water and add bleach to it and let it sit for a few hours. My tub is also porcelain. It whitens the tub and disinfects it too. I'm not sure about it removing rust stains, but it's worth a try. If it doesn't work, ZUD will.

Answer 3

BarKeeper. You can buy it at Walmart around $1.59. You'll never use Ajax again. It will remove rust and bleach out the tub. Damp the tub then just sprinkle on and smear around. Let it set and it will be white and rust free.

Answer 4

For the environmentally healthy option:

Use half a lemon and sea salt to scrub the tub.

Less smelly than vinegar and you won´t´need a sponge since you are scrubbing with the lemon.

Answer 5

CLR works well to get rid of rust stains.

Answer 6

CLR
c-calcium
L=lime
R= RUST

Answer 7

I would try comet or ajax. I use them on my sink and it is porcelain. Try to find the less abrasive kind. Hope that helps.
