2. Initial Preparation: Cleaning & Drying

Think of winter storage as giving your pontoon a “deep clean” before tucking it in. The steps you take here will impact how well your boat holds up in storage:

1. Clear the Deck: Remove all personal items, coolers, fishing gear, and seat cushions if possible. Store them in a dry, indoor space.
2. Wash Thoroughly: Use a mild marine detergent to remove algae, grime, and salt (if you boat in saltwater). Don’t forget the underside of the deck and the pontoons themselves.
3. Clean Upholstery: Scrub and rinse any seats or cushions that can’t be removed. Let them fully dry to avoid mold.
4. Dry Everything Completely: Moisture is the enemy in winter storage. A leaf blower or shop vac can help remove water from crevices.

Tip: Novelli Boats feature foam-filled hulls and corrosion-resistant 5083 aluminum, which both reduce the risk of water intrusion and long-term damage. Still, it’s essential to ensure that all surfaces are clean and dry before your pontoon goes into hibernation.
