Comstar International 55-121 Grease Cutter Degreaser 16 Oz

Product Description

The COMSTAR INTERNATIONAL 55-121 is a biodegradable aerosol degreaser formulated to remove oil-based grease, tar, dirt, grime, slime, carbon, and engine deposits from a wide range of surfaces. The formula is non-chlorinated and CFC-free, air-drying after application without leaving a film behind. It is safe for use on plastics and metals, making it a practical choice for HVAC technicians, plumbers, electricians, and mechanical service pros who need a fast-acting degreaser that does not require rinsing. The citrus-scented formula is USDA authorized and will not contaminate waste oil, supporting proper waste-oil disposal procedures.

The 55-121 is suited for commercial and residential service applications where grease and hydrocarbon buildup must be removed quickly from equipment surfaces, coils, motors, and mechanical components. The no-rinse, air-dry action makes it especially useful in situations where water rinse-down is impractical. It is packaged in a 16-ounce aerosol can for controlled, targeted application in the field or shop.
