What's the best way to clean all the crud off the K5's engine? I use Simple Green usually to wash my machines, and it keeps them clean. However, since I just purchased this used K5, it has a bit more baked on crud then what I would let my machines get on them. So, Purple Power and a tooth brush? Or what about Engine Brite? Would it be to strong on aluminum parts all over?
I searched on this subject and found mixed reviews, seems like most like purple power, but haven't heard anything on Engine Brite. I want to do the best I can to make that machine look like it came off the showroom floor.
Thanks!
