West Marine Salt-Off is a powerful engine flush and corrosion inhibitor designed to combat the harsh effects of saltwater exposure on marine equipment. This concentrated formula effectively removes salt deposits from multiple surfaces including fiberglass, aluminum, stainless steel, rubber, plastic, magnesium, and painted surfaces. What sets this product apart is its unique PTEF protective coating technology, which creates a durable polymer barrier to prevent future salt accumulation and corrosion. Perfect for boat maintenance, it can be used as a motor flush for I/O and outboard engines, helping extend the life of marine engines operating in salt water environments. The 1-gallon size provides ample solution for treating boats, fishing tackle, dive gear, trailers, and other marine equipment. Laboratory testing, including the rigorous Humidity Cabinet Test (ASTM D 1748), demonstrates Salt-Off's superior performance in preventing surface corrosion compared to competing products. This biodegradable formula offers comprehensive protection for all your valuable marine investments, making it an essential addition to your boat maintenance routine.
