Title: How to remove rust stain from shell
Post by: bwspa on July 24, 2019, 11:42:37 am

I have some rust stains forming on the top of the shell above the water line near the diverter.  What is a safe way to remove this?  I do not have high iron water (actually have high hardness city water).

Tub is white so it shows very easily.  Thanks

Vinegar and baking soda

If the vinegar and baking soda doesn't work, try Goof-Off on a rag

I stuff Vitamin C tablets in a small sock and then use it like a sponge - if that makes sense - to wash them off.
