Collinite 83 Boat Wash Shampoo
Use for ordinary dirt and regular maintenance. Wash from the top down, rinse thoroughly, and dry before applying wax or protection.
Start with the condition your boat is actually in. Each path explains the process first, then shows a matching Sonark Marine product when stocked; third-party options are used only when they add something different.
A regularly washed boat does not need the same products as a chalky, oxidized hull. Salt exposure, mildew, and neglected gelcoat each call for a different approach.
Use only the product needed for the condition. More chemicals do not automatically mean a better result.
Choose the condition that best matches your boat, then jump straight to the recommended process.
