My 70 year old porcelain bathtub has light gray stains in the bottom.

by Plasmyer
They look like the tub is dirty, but no matter what I scrub with, ajax, tcp, bleach,etc, they don't come off. Is the porcelain damaged, any hope?

    Try Clorox toilet bowl cleaner. It worked well for me.

    Hi. Ooooohhhh my sister did the toilet cleaner on her tub and it sadly ended up scrap. I think it would depend on the what the tub is made of. But, Irene might have the answer for you. Good Luck ......Gigi

    The porcelain has been scratched and probably gone down to the metal. There is no cleaning that will solve this. The tub needs to be refinished.
