How to seize rid of a hip bath ring surrounded by a topical Kohler plastic tub. Have tried Comet, bleach, scrubbers, baking soda ...
baking soda and vinegar
My mother sometimes rubs Tide with Bleach on the tub and let it sit..
Our tub is one of those old unhealthy deep tubs. I think about it may work on plastic as well.
Answers: have u tried the trickery erasers???? they are great
