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, and it incorporates two surfactants, including duPont's Merpol®. 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.
Features and benefits:

• High hard water tolerance
• Deep penetrating, foaming cleaner
• Safer and less corrosive than HF-based cleaners
• Low odor
• Biodegradable
• Safe for use on indoor coils
