Hello, I used this on my 2 stroke snowmobile to remove exhaust soot from the side of my machine. 92% of it melted right away and hosed off with water . The most stubborn part was right next to exhaust pipe and needed to work at it with a brush to remove soot. Only thing Ive found that works for this exhaust stains. Thanks Don St.Onge

Used it full strength to remove stains and soot build up. Took some scrubbing and multiple applications but was a able to bring the finish to the paint. Need some wax after. I’ll stick with this product, enviro safe, non corrosive and no bad chemical smell.

Excellent product. Soot just runs off the aircraft when you spray it on.

This product works wonders, even diluted. It is great at removing bugs and even fragments of wax that get stuck around rivet heads. The price cannot be beat. I use it on all my vehicles and recommend it.

Tried this product to remove the exhaust stains on the paint and the results were even better than I expected, much better than using other means.
