The YachtGUARD® Premium Boat Wash System is a state of the art high pressure boat wash and spot free rinse system all in one. The YachtGUARD® System uses clean clear soft water for your initial rinse and soap application. By removing all the minerals typically found in dockside water and using the supplied Foam Cannon, you will use 80% less soap and loosen more dirt without brushing or scrubbing and damaging your wax finish. Once you rinse off the soap with the soft water, with the turn of a valve you can do a final spot free rinse using the built-in high capacity Deionized Water system. Then just walk away and let the boat dry to a sparkling spot free finish. No drying needed. When you're finished, switch back to the soft water and fill your holding tank with clean sparkling fresh water.
