While I have the engine out of my car for my beta swap I'd like to clean up the engine bay a little. My first step is to remove some of the oil/grease/whatever that has built up over the years but all of the degreasers I have handy aren't recommended for use on paint.

Anybody know of one that will be okay to use on my paint?

 

Simple Green and a nylon bristle brush. What I use.

For really tough stuff, you can use WD40, then Simple Green.
