yea i have tried that simple green in the foamy spraycan on my engine. amazing stuff! works so much better than gunk on my engine and is much safer for the engine too. gunk just smells like its not good for your paint or engine parts, and is toxic and bad for the environment
although i was in home depot the other day and now(i dunno how long its been out lol) simple green has this stronger purple stuff in a concentrated jug im going to try. its for automotive and it overall stronger degreaser stuff thats still safe on everything. i mgonna try it on my engine and undercarriage
