Star Brite 98932 Ultimate Fiberglass Stain Remover Gel Spray 32 oz

The Star Brite Ultimate Fiberglass Stain Remover (98932) is a marine-grade, gel-formula stain remover engineered to tackle the most stubborn stains on fiberglass and painted surfaces. Unlike thin liquid spray cleaners that run off before they can work, this gel formula clings directly where applied — maximizing contact time and cleaning power without dripping or wasting product.

Formulated without caustic acids or phosphates, it safely penetrates and dissolves yellowing, rust stains, waterline deposits, dried fish blood, and leaf tannin stains. The gel fully covers the stain surface to lift and break down even the most set-in discoloration. Its thick consistency makes it especially effective on vertical surfaces such as hull sides, transoms, and RV sidewalls.

Key Features:

• Gel formula clings to surface for maximum contact time and cleaning power
• Removes yellowing, waterline stains, rust, dried fish blood, and leaf stains
• Completely covers and penetrates stains to dissolve them at the source
• Free of caustic acids and phosphates
• Works on all fiberglass and painted surfaces
• Ideal for vertical surfaces — gel won't run or drip
• Suitable for boats, RVs, and other outdoor fiberglass applications

Directions: Spray directly onto the stained area and allow the gel to soak in until the stain disappears, then rinse thoroughly with fresh water. For stubborn stains, allow additional soak time, then apply light scrubbing before rinsing. Always test on a small, inconspicuous area before treating large surfaces.
