I came to live in my stepmother’s mobile home to care for her. The toilets are brown. They look filthy when they are clean. Is there any way to get them white again, or do I have to replace them? New toilets are expensive, and I’m afraid used ones will have the same problem I already have.
If acid does the trick, is it safe for a septic tank? Better to remove the toilet and clean it outside? Can they be enameled to make them white again? I really know nothing of plumbing stuff.
