Okay, so I've got this G1 Devestator. Absolutely complete, good paint, good joints, but lousy stickers. I've got a set of Reprolabels ready to go on. I've spent this afternoon carefully removing all of the stickers from every part of Devestator except for the rub-signs. The Constructicons came all dirty. Not too dirty, but look's like old dirt and dust that was never cleaned off and dirt in the cracks and just not shiny and pretty. What's the next step for this restoration? I have a soft toothbrush, and I have dishwasher hand soap. I think it's Dawn antibacterial hand soap. Can I just mix soap with warm water in a tub and soak the Constructicons and their parts over night? Will that clean em up and brighten them? Will this also remove any remaining sticker glue? Will it harm the chrome? I don't want to use Goof-Off because I notice it rubs off some of the plastic. I've got no plans to repaint these or customize them, just a good professional restoration. All stickers are off. Advice please?
