NU-CALGON 4166-75 Evap-Fresh No Rinse Evaporator Coil Cleaner and Disinfectant is a ready-to-use aerosol formulated to clean, deodorize, and disinfect evaporator coils in one simple application. This no-rinse solution is designed for use on small air conditioning cooling coils, refrigeration equipment, and refrigerator or freezer evaporative coils where effective sanitation and odor control are required.

Evap-Fresh produces a penetrating foam that clings to coil surfaces, cutting through dirt, grease, and organic buildup while eliminating odors at the source. The disinfectant formulation helps control bacteria, fungi, mold, and mildew on hard, non-porous surfaces, making it suitable for environments where cleanliness and cross-contamination control are critical, including homes, schools, hotels, hospitals, nursing homes, and food processing facilities.

The aerosol can is engineered to spray in any position, including upside down, allowing easy access to hard-to-reach areas inside HVAC and refrigeration equipment. Once applied, the foam penetrates the surface and remains wet for the required contact time, then breaks down without leaving grit, residue, or soap scum. In most applications, rinsing is not required. A fresh lemon scent helps neutralize unpleasant odors during and after use.

This product is EPA registered and provides bactericidal, fungicidal, and mildew-control activity when used as directed. It must be applied in accordance with label instructions and is intended for professional HVAC and maintenance use.
