Gunk Engine Degreaser spray 15 oz – Original formula, fast-acting rinse-away cleaner for baked-on oil & grease

GUNK Original Engine Degreaser is a professional-strength spray that dissolves baked-on oil and grease so you can rinse engine bays clean without heavy scrubbing.

This concentrated degreaser is engineered for vehicles and equipment that see serious wear and grime. Its fast-acting solvents penetrate layers of old oil, grease, and road film to lift contaminants from metal, rubber, and plastic surfaces. Designed for both professional mechanics and weekend DIYers, the 15 oz aerosol delivers controlled spray coverage and rinses away with water, making engine cleaning faster and neater than using detergents or manual scraping.

How quickly does it break down heavy oil and grease?

The formula works within minutes to soften and dissolve thick deposits so they can be rinsed away. For most heavily soiled areas allow 10–15 minutes for full penetration before hosing off. Avoid letting the product dry on hot surfaces to maintain performance.

• Action time: typically 10–15 minutes
• Effective on baked-on and fresh grease
• No aggressive scrubbing required for most deposits

Can I use it on different vehicles and equipment?

Yes—this degreaser is suitable for cars, trucks, motorcycles, ATVs, lawn mowers, tractors, RVs and many other gas- and diesel-powered machines. It’s formulated to tackle the grime commonly found on older, high-mileage engines as well as routine maintenance cleaning.

How do I apply it for the best results?

Spray evenly over the greasy surfaces, allow the product to soak in for the recommended time, then rinse thoroughly with a hose or pressure washer. For very thick deposits, repeat application or agitate lightly with a soft brush after the dwell time, then rinse.

• Shake can well before use for uniform spray
• Saturate targeted areas from 8–12 inches away
• Wait 10–15 minutes, then rinse with water
