How to remove stains from a fiberglass tub
This stuff works for me in my tub: https://amzn.to/2X29pxg
There is a cleaning product called Spray Nine that works fabulously on fiberglass paired with a Mr. Clean Magic Eraser. I hope this helps!
Thanks for the suggestions..
Lysol Lime & Rust Remover Toilet Bowl cleaner, comes in a black squirt bottle. Scrub with Scrub Daddy or Mr. Clean Magic Eraser.
