Hey everyone! As the title states, I'm interested in the best way to thoroughly clean an old (~5 years) motherboard. I just built a new rig and want to use my old one as a test subject for things I haven't tried yet in my 22 years of building. I have yet to delid a processor or run a custom loop - I'm not sure I'll waste the money to run the custom loop on this (i5-4670k, Maximus VI Hero), but I just ordered my Rockit 88 and some CLU to attempt my first delid. The plan is to completely disassemble the old comp, clean EVERYTHING to like-new condition, delid/relid the 4670k, put new thermal and thermal pads on the GTX 770 and use it as a Linux box. I have read dozens of articles, watched dozens of videos, etc. I'd rather have a discussion here with user's actual experience and opinions. The board is not bad, but it's not great either. It's past the point of blowing everything off with my Metro Datavac. I'm currently considering the Hosa CAIG DeoxIT 5% Spray Contact Cleaner, WD-40 Specialist Electrical Contact Cleaner and CRC QD Contact Cleaner. I would like the board to look as new as possible without having to use a brush on the PCB. I think a soft nylon brush will be okay for a few of the components but I'd rather not take a brush to much else. Does anyone have experience with any of these products? It seems simple enough - you get as much off as you can with air, then use contact cleaner to saturate the motherboard and let dry completely. Any advice would be greatly appreciated! One of the videos I watched, the guy was Australian and unfortunately I can't order what he used. He finished everything off with this board laquer that really made everything look like new. I can't find anything like it on Amazon. Hope to hear from you guys soon! Have a great day and Happy Mother's Day!
