MP 20th Ani Prime weathering removal

Hi,
I really want to get this guy to play around with. I'd pickup the tall smoke-stack upgrade also, but whats holding me back is what to do about the weathering?
Does anyone have experience or have any links for tips on how to DIY remove the weathering on him without harming the paint / plastics?
Cheers!
