How to Clean a Fiberglass Boat Deck

You likely take pride in keeping your boat’s interior and hull clean, but have you paid enough attention to your deck? Cleaning a fiberglass boat deck doesn’t have to be a tedious or back-breaking task. With the right preparation and cleaning methods, you can achieve a spotless deck in no time. Here’s a step-by-step guide to make the process simple and effective.

Prepping the Deck

Proper preparation is the key to a clean, streak-free deck. Follow these steps to ensure your deck is ready for cleaning:

• Brush off debris: Use a push-broom or a microfiber dusting glove to remove loose debris from the deck. Removing dirt before applying cleaning products will prevent streaks and scratches.
• Rinse thoroughly: Rinse the deck with freshwater to loosen any remaining grime. Allow the deck to dry completely before stepping on it to avoid slipping.

Cleaning the Fiberglass Deck

After prepping the deck, it’s time to clean. Using the right materials will make the process easier and more effective. Here are some cleaning tips:

• Choose a non-phosphate cleaner: Opt for a marine-safe, biodegradable cleaner designed for fiberglass. Mix it with water to cover larger areas efficiently.
• Tackle adhesive residue: For tough adhesives or sealants stuck to the deck, use an adhesive remover specifically designed for fiberglass. This will safely lift stubborn residue without damaging the surface.

Use a long-handled squeegee or soft-bristled brush to clean the deck systematically. Start at the edges and work your way inward, ensuring safe and stable footing throughout the process. Be cautious when cleaning near edges to avoid slipping.

Maintaining a Pristine Deck

Regular cleaning is essential to keep your fiberglass deck in top condition. Incorporate these habits into your maintenance routine:

• Rinse the deck with freshwater after each trip to remove salt, dirt, and debris.
• Inspect the deck for scratches or stains and address them promptly to prevent permanent damage.
• Use non-abrasive cleaning tools and products to preserve the deck’s finish.
