What it cuts, in plain terms.

Removes the brown stain, oxidation and buildup at the waterline.

For marine fiberglass, gelcoat and painted hulls above the waterline.
Work In Sections

Where to use it — and where not
The specifics: Boat and RV hulls collect a brown waterline stain regular soap won't move — mineral scum, oxidation and organic staining baked in at the waterline. This is built to cut it. Confirm it's right for your hull's finish, work in sections, and rinse.
This is purpose-built chemistry — that's the point. On the surfaces it's made for, it cuts grime gentler products can't touch. On the wrong ones it can do harm, so we're specific instead of vague. Work a manageable area, don't let it dry, then rinse or wipe thoroughly.
