I started my Classic last night after waaaay too long, got no bong and a simasimac-like pattern on the screen. I cracked it open and discovered quite a mess. Battery gunk and corrosion all over the place. I've got the chassis soaking in Evaporust, and I soaked the logic board in IPA overnight & scrubbed it with a nylon brush. What would be the best option to remove the rest of the corrosion on the motherboard: vinegar, WD-40, or something else? In addition to a new battery holder and recapping, I know I'll need to at least replace Y1and R85, 86, 88, & 89 on the bottom; but what about D1 and D2, do they need to be replaced? Have I missed anything else? Some of the legs on UA2/UA5 are green; are they/the rest of it salvageable?
