Gilbert's Hull Cleaner & Brightener

• Advanced Oxalic Acid Formula: The active oxalic acid component targets and dissolves organic stains, rust, and tea-staining on contact, lifting them directly out of the porous fiberglass gelcoat.
• Integrated Surfactant Boost: Engineered with built-in surfactants (surface-active agents) that break down oily scum, road grime, and greasy exhaust residue that standard acids leave behind.
• Stay-Put Smart Gel Technology: Our slightly gelled consistency clings tightly to vertical surfaces and overhead hulls. This maximizes contact time and prevents wasteful run-off, meaning less scrubbing for you.
• Cleans & Brightens: It doesn’t just remove dirt—it chemically brightens yellowed fiberglass, making older hulls look crisp, clean, and revitalized.
• Fresh Orange Aroma: Say goodbye to choking, acrid chemical smells. Enjoy a refreshing, crisp citrus scent while you work.

1. Apply: Brush or roll Gilbert's Hull Cleaner onto a dry hull, starting from the bottom and working up.
2. Dwell: Let the smart Cleaner work its magic for 5–10 minutes (do not allow it to dry). Watch the yellow stains disappear.
3. Rinse: Agitate lightly with a soft brush if needed, then rinse thoroughly with fresh water to reveal a dazzling, bright finish
