"Used to clean the cooling fins on industrial, residential and automotive air conditioning units. Can also be used on auto radiators, small air cooled equipment, metal filters and more. Pinpoint jet force tip propels the formula to its intended target, including hard to reach places. The dual quat foaming action expands and flushes contaminants out of the coil and deodorizes drain pans. No rinse necessary. Lack of proper maintenance can have several negative effects: the unit works harder, the unit life decreases, food may spoil faster, and utility costs can increase dramatically. Regular use allows the unit to function more efficiently for longer periods of time."
