CalClean is a formulation of liquid detergents, containing a perfect balance of surfactants, grease solvents, alkaline cleaners, corrosion inhibitors and water conditioners. It is a concentrated detergent designed to be diluted with four to ten parts of water; best results are obtained when applied with one of the Nu-Calgon sprayers. It is also NSF Registered A1/K4 and is safe for Cleaning HVAC/R Coils in Food Processing Areas.

Greasy dirt and dust in the air can collect on air-conditioning and refrigeration heat exchange units. If these finned heating or cooling coils are left unclean, heat exchange is cut down, compressors have to work much harder, costs go up and often valuable equipment breaks down when it is needed most. In addition, clogged and dirty permanent filters cut down air flow and do not filter air, allowing dirt to contaminate rooms and stain walls around air ducts.

Regular cleaning with CalClean protects equipment and helps it to operate to peak efficiency.

This product must be used in accordance to the following directions by HVACR professionals only.

On heavily soiled coils or filters, CalClean is most effective if it is mixed with four parts of water and sprayed on both sides of coil or filter. Permit the detergent solution to remain in contact with the dirty surfaces for about 5 minutes, then flush off with water from a hose (with as high a pressure as possible).

When cleaning permanent filters or other greasy parts in a tub, use 1 ounce of CalClean for each gallon of water. Allow to soak for 15 minutes and then flush, preferably with water from a high-pressure hose.

CalClean can be used where there is sufficient condensate being pulled from the air. The cleaning solution should be mixed at a ratio no stronger than 10: 1.
