Star brite Marine Descaling Fluid Ready to Use 3,78L

When a boat or motorboat is operating on lakes or seas, its engine uses external water for cooling. Over time, a thick layer of limescale, minerals, saltwater salts and corrosion deposits inevitably accumulate in the internal channels of the engine block. This deposit narrows the channels, impairs cooling and can cause dangerous engine overheating. This fluid effectively dissolves even stubborn limescale and salts, but is factory-designed so that it does not damage rubber seals, gaskets, cooling hoses and plastic parts.
