Hi all. I have a very old cast iron tub on which the finish (porcelain?) is worn off in one spot that has been dripped on for years, and worn flat all over. Because it's lost all shine, the stains from rust and soap scum just won't come off. I've tried all kinds of cleaners and scrubbing. I've even dumped a whole gallon of bleach into the tub full of hot water and let it soak for hours. No good.
However, a few months ago, we had a slow drain. I poured a foaming drain cleaner into the drain, and the foam kind of built up on the tub around it. Lo and behold, it was pure white where the drain cleaner had foamed.
So, I'm wondering if it's a good idea to pour drain cleaner all over the tub and let it sit for a while, then rinse it off. Or would I be doing more harm than good? This tub's days are numbered, as we're hoping to renovate in the next few years, and I'm tired of looking at gray stains everywhere. But.....I don't want to do anything stupid. So what do you think? Is it a good plan? :help:
