| Hi Eddie, welcome.
What a grand loco you have there.
Brake fluid, Dot3 preferred over Dot4, would remove the paint, it works well on plastic and is not too severe. It is also easy to neutralize by washing thoroughly with water.
Check out a bottle at the retailer though as i don't know how it reacts to various metals; steel and brass should be ok but copper/zinc?
Hopefully one of the engineering modelers will be along to help out.
