KOIL KLEAN is formulated to penetrate air-conditioner coils and fins to remove all types of soils. Upon contact with the surface of the coil, KOIL KLEAN begins to react and flush soil to the surface. It is not necessary to rinse if applied in place to a functional unit that produces moisture. The moisture produced will rinse product from contacted surfaces. Rinsing is required on units that have been removed for repair or do not produce moisture during operation. An excellent product for air conditioners, central cooling systems, and auto air conditioners. For use in hotels and motels, homes, office buildings, air conditioner services, and auto repair services.
