Star Brite 81732 Instant Hull Cleaner 32 oz Wipe-On Rinse-Off Formula

Star Brite Instant Hull Cleaner (81732) is a powerful, easy-to-use marine cleaning solution formulated to begin working on contact. Designed with a naturally effective oxalic acid formula, it quickly dissolves tough waterline deposits, scum lines, rust stains, and organic stains from boat hulls without the need for scrubbing or rubbing. Safer than cleaners containing harsh hydrochloric or phosphoric acids, this 32 oz quart is an essential part of any routine boat maintenance program.

Key Features:

• Instantly removes waterline stains, scum lines, rust, dried fish blood, grass, and leaf stains on contact
• Simple wipe-on, rinse-off application — no rubbing or scrubbing required
• Oxalic acid formula delivers strong cleaning performance without harsh hydrochloric or phosphoric acids
• Safe for use on fiberglass, plastic, metal, and painted boat hull surfaces
• Will not harm the surfaces being cleaned — ideal preparation step before hull polishing
• Apply using a sponge or sprayer; rubber gloves recommended
• For best results, use when temperatures are above 50°F (10°C)
• Proudly made in the USA since 1973

Directions: Shake well before use. Apply with a sponge or sprayer. Allow to remain on the surface for approximately 2 minutes, then rinse thoroughly with fresh water. Severely stained surfaces may require a second application and light scrubbing. Follow up with Star Brite Premium Marine Polish to restore shine and protect the hull.

Note: May cause discoloration on anti-fouling bottom paints. Also available in gallon size (81700).
