Star brite 1 Gallon Heavy Duty Boat Bottom Cleaner

The one-gallon Star brite Boat Bottom Cleaner is an acid-based formula for staining and mineral deposits on hull bottoms. It targets the yellowing and waterline buildup that conventional soap may leave behind. This is a specialty hull cleaner, not an everyday wash for all surfaces.

Remove the boat from the water and let the deposits dry before applying cleaner to the bottom. An all-plastic sprayer or compatible non-nylon brush can be used to keep the stained area wetted while it works. Foaming indicates the cleaner is reacting with deposits. The chemical should be kept off finishes not approved for this type of acid cleaning. After roughly ten minutes of foaming action, rinse the surface with water. Thick deposits may need another application and light scraping.

Because the chemistry is aggressive, follow the label for personal protection, ventilation, surface compatibility, rinsing, and waste disposal. Do not combine this cleaner with bleach or other chemical products. Test a small appropriate area first if the finish or coating is uncertain.
