Lake Simcoe Boat Winterization & Hull Restoration
Chemical Acid Wash Breakdown: Restoring a Heavily Stained Hull

Before shrink-wrapping your vessel for the winter, removing the season's heavy organic growth, mineral scale, and stubborn yellow "tea staining" is critical to protecting your fiberglass. When boats sit in local marinas for months, algae and calcification anchor themselves deeply to the hull. Attempting to blast this off with brute-force pressure washing is ineffective and risks damaging the gel coat.

Watch our exact process for premium hull restoration using applied chemistry rather than damaging high pressure. In this breakdown, we utilize a specialized, undiluted hydrochloric acid-based detergent (OneRestore). By brushing the product on and allowing the correct chemical dwell time, the acid safely dissolves the mineral scale and breaks down the organic anchors. This allows us to easily melt away the grime and brighten stainless steel props and trim with a low-pressure hot water rinse.

Whether you need a standard end-of-season maintenance clean or a comprehensive two-step restoration for deeply embedded anchors, our chemical protocol ensures a factory finish. Protect your investment before the freeze—watch the full process and secure your spot on our fall schedule today.
