Cleaning the outside, '85 Rebel 250

[w8lifter21]

New to me today 1985 Rebel 250, looking for some advice on how to clean the engine and maybe the chrome. Sure I could just pull it and repaint, but it'd like to see what cleaning would do first . Thoughts on what or not to use on the outside of the engine? If anyone has any good products on cleaning the chrome, I'll take that too lol!

Here's what I'm working with, basically 16 years of garage storage.....
