Thanks for your reply to my posts. I got so many good suggestions that I don’t know which one to try first. I guess I’ll try the one that easiest to come by.
Oooops. I don’t know about Denture Adhesive remover. I was just thinking of the tablets like Efferdent that remove stains. I heard of using them for stained toilets. A bathtub would be on a larger scale so I don’t know how many tablets it would take.
