I've read this is the best/easiest way to clean my engine. It's covered in water spots and sand and just general garbage from years of trail riding and being driven. I dont need it to look like it just came off the showroom floor, but I do want to get my engine atleast looking decent.
So, cool engine, engine off, spray on simple green (do you dilute it? I've read some do it either way), let sit for a moment, and then spray off. That's all there is too it?
