how do you clean up a used engine

Oh my. Gasoline?
Yes, I've done it but it isn't a good idea.
The story back in the day is that someone used a synthetic brush and the static actually ignited the gas.
I don’t know about that.
But the fumes of gasoline are very flammable.
Remember the people on camera who get in and out of their cars and the static ignites the tank?


the flammable part might not be a bad thing .....last winter i was cleaning up an engine and there was a spot of really stubborn grease so i soaked it with carb cleaner and lit it on fire and the heat made the grease come off easier and some of the grease burned off.......


i set off the smoke detector and my dad said i was crazy but it got the job done.
