303 Products Boat Wash 32 oz, Ultra-Concentrated Marine Wash with 30-Day UV Protection

303 Boat Wash is an ultra-concentrated marine cleaning formula built to break down dirt, grime, salt accumulation, and stains left behind after a day on the water. Each 32 fluid ounce bottle is designed to be diluted, so a small amount goes a long way across multiple wash sessions. The formula is pH neutral, meaning it cleans thoroughly without stripping wax off your boat's paint, gel-coat, or fiberglass finish. Beyond cleaning, 303 Boat Wash provides up to 30 days of UV protection with every wash, helping guard against fading and sun damage between details.

This wash is 100% biodegradable and marine safe, making it appropriate for use around water without added environmental concern. To use, add 1 ounce of 303 Boat Wash to a 5-gallon bucket, fill with clean water, wash the boat, rinse completely, and for best results hand dry surfaces with a microfiber towel. The result is a deep clean, spot-free, sparkling shine without leaving behind a greasy or hazy residue.
