doing an upgrade and i knowwww the thermalright ultra extreme 120 is gunna be a bit dusty 
now going to do the usual can of air and a paintbrush and clean off all my components....but how do you guys (and gals
) get the nitty gritty off the heatsink fins?
the canned air well get rid of most but there's always that thin layer of particulate that is like film covering them... what's the best way to get rid of this muck?
chuck it in a bowl of hot soapy water? xD (semi serious about it....)
what ya think? bowl of water? cleaning agent on a wool string and pull it between all the fins? just keep using my lungs on it?
