Concentrate | Gallon Designed to safely and quickly remove scale, calcium deposits, corrosion, salt, and carbon buildup in your raw water-cooled systems. These deposits can cause your engine to run hot or result in AC system inefficiencies by restricting water flow through the cooling jackets, tubes, and heat exchangers. Calcium and scale buildup also may damage your water pumps if debris is dislodged and allowed to flow down into the pump housing. Descaling Fluid WILL NOT damage seals, gaskets, rubber impellers, or hoses. Can be recirculated through any system where descaling is needed. Recirculation allows for minimal dismantling and a faster return to service for equipment. The product can also be used as a soak by submerging components in the fluid to eliminate deposits. NOTE: Marine Descaling Fluid may discolor some metals, chrome coatings, stainless and alloys. Proper education on how each system operates is critical before using Marine Descaling Fluid. Star Brite is not responsible for damages due to improper procedure or use of the product. Mix 1 part Descaling Fluid concentrate for every 4 parts fresh water for all applications, including recirculating and soaking.
