STAR BRITE Instant Hull Cleaner - Easily Remove Stains, Scum Lines & Grime for Boat Hulls, Fiberglass, Plastic & Painted Surfaces - Wipe On, Rinse Off Formula

Q: Hi, we have what appears to be a calcium buildup on our carbon fibre kayaks with a painter gel coat, would this be ok for use on those?

I have to say, even though this product had great reviews. I was unimpressed. Our boat had yellow staining and even with several applications it didn’t help.
