Cal-Brite is a low-pH or acid-based product developed for cleaning evaporator coils, air-cooled condensers and other finned cooling and heating coils. It is based upon glycolic acid and ammonium bifluoride. The activity between the glycolic acid and the ammonium bifluoride produces a synergestic cleaning effect, resulting in a clean, brightened coil but with the utmost in safety to the applicator and the job site as compared to HF-based products.

Shake before using. Also, wear safety goggles, gloves and personal protective equipment. Do not mix chemicals.
If the coil is heavily soiled with lint, hair and other heavy soils, use a brush to remove this matter prior to using Cal-Brite.
For normal to heavy soils and grease, dilute 3 parts water to 1 part Cal-Brite. For light soils, dilute 6 parts water to 1 part Cal-Brite. Also, when cleaning evaporator coils be sure the condensate pan and drain are clear to insure proper draining of cleaning solution and rinse.
Shut off the system as well as blowers or air handling equipment prior to cleaning. If using indoors on an evaporator coil, be sure nearby registers are closed. Although the blower was turned off, natural air currents could pick up and entrain droplets of cleaning solution and this should be controlled.
Spray diluted Cal-Brite onto coil with a low pressure sprayer. Avoid back spray.
Wait 5-10 minutes, then rinse coils thoroughly with water. Take your time to insure complete cleaning.
After cleaning, treat coil with Cal-Shield® coil protector (4148-08).
