Absolutely. The all-purpose boat soap's wash-and-wax formula works excellently on any vehicle. It's gentle enough for clear coats and gel coats while providing UV protection and water beading. Many customers use it as their go-to cleaner for boats, cars, RVs, and even aircraft.
After every saltwater use, flush your engine with fresh water mixed with salt remover concentrate. For boats kept in saltwater, flush weekly even without use. This prevents salt crystallization, corrosion, and cooling system blockages. One gallon of concentrate typically provides 8-16 flushes depending on engine size.
