Sheldon,
I am litteraly addicted to Brake Cleaner, on any given night I can go through about 3 cans of Brake cleaner. And I’m only spraying 2 cans on the kart 😉 :oOo :oOo .
Super Tech also sells a Engine degreaser I like a lot.
For me its,
1. Brake Cleaner
2.Simple Green (Not dilute)
3.Super Tech Engine Degreaser
4.WD 40 for bearings and stuff like that
Hope that helps 🙂
