A purpose-built exterior hull cleaner that cuts through the grime most freshwater rinses leave behind. Lippert's 2022013934 tackles scum lines, rust stains, lime deposits, gas exhaust residue, and yellowing on fiberglass and painted boat surfaces -- no acid, no bleach, no solvents required. Spray it on, scrub, and rinse for a noticeably cleaner hull without damaging your gelcoat or topside paint.
Waterline scum, exhaust soot, mineral deposits, and oxidation-driven yellowing are some of the most stubborn stains a boat owner deals with. Many cleaners that cut through those deposits do so with strong acids or solvents that risk dulling gelcoat, stripping wax, or leaching harmful compounds into the water. Lippert's hull cleaner uses an environmentally friendly, acid-free and bleach-free formula that loosens and lifts deposits without attacking the underlying surface.
At 32 oz in a ready-to-use spray bottle, it is a practical size for dock-side touch-ups, seasonal cleaning sessions, or keeping aboard as part of a regular detailing kit. The spray-on application means no mixing, no dilution math, and no separate applicator pump.
Formulated to cut through scum lines, rust streaks, lime scale, and gas exhaust residue that accumulate at and below the waterline on boat hulls.
Works on gelcoat, fiberglass, and painted hull surfaces without etching or dulling. Acid-free and solvent-free chemistry protects your finish.
Penetrates and loosens oxidized yellowing and tough mineral deposits, making them easier to scrub away without aggressive abrasion.
Ready-to-use 32 oz spray bottle. No dilution needed. Apply directly to the affected surface, scrub lightly, and rinse clean.
