Quoted from PinballFever:
I decided these clean metal parts would look out of place against the dirty frame so it needs to be cleaned too.
I tried toothpaste with toothbrush, simple green and citrus degreaser but the frame still looks grimy as you can see.
Any tips? I may try Awesome or whatever that stuff is at dollar tree. There has to be a solution that will clean this grime off the zinc coating. (I want to clean around the labels so I can leave them original on the frame)[quoted image]
With most nickel plated parts I normally do an initial parts wash to clean off grime/grease then give a soak in evaporust. I find the evaporust gives a really nice original sheen on the whole part.
