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.
Designed for use on metal and plastic surfaces commonly found in HVAC, plumbing, electrical, and mechanical service environments where oil-based contaminants require removal.
Applied by licensed or qualified service technicians during routine maintenance or equipment cleaning procedures. Power down and de-energize equipment before applying any aerosol degreaser to electrical components or motors. Allow the product to fully air dry before restoring power or reassembling components. Use in a well-ventilated area and follow all applicable safety data sheet guidance for aerosol solvent products.
