Any tips for getting loose figures clean? New to the collecting so not sure about any issues. When I get one should I just leave it well enough alone? Try to remove the dirt and grim? Wondering after I just picked up a weequay what really seems to be in great condition, tight and no wear I can see at all. It just does have two small dots on the back of one of his legs. Won’t try and cover them up at all but is it ok to try and clean him and see if they come off and if so what would be the best way to do that?
