I was wondering as for cleaning the fret board, what cleaner can help get that gunky build up off the fret board? Should I use polish afterwards? I Have some string ease.

It says on the can that it also cleans, I'm not sure about that, but is it sufficent as a polish after cleaning?

And my other question is about the body. The paint on my guitar is flat. Would you clean it the same way as you would with a glossy finish?

Any help is appreciated.
