(Solved) - Best way to clean aluminum heatsink?(11 posts)
Brushing can create static so, though it will be a PITA, it may be necessary to remove the heatsink, then brush, wash, whatever it takes to get it clean. One possible reason the dust is sticking so tenaciously is it may be a bit corrosive and is etching into the metal (aluminum is especially susceptible to this). Once clean, more frequent dusting with compressed air or “canned air” may be able to prevent this. Another possible reason for the dust sticking like glue is tobacco smoke residue may be gluing it down. The only cure for that is to not smoke in the same room as the computer (even that may not help if smoke is circulated through the house by the heat and or air conditioning system).
Once I use up the last of my “canned air”, I'm going to get the same blower Xhi has.
No. But if it has already started to oxidise, Then I would do that, and then spray it with black satin HT teflon paint.
You could give it a clean inbetween those 2, with nitric acid as well.
I used to use helicopter fuel, but then I had a free source.
"Toon Brite" is an aerosol product used to clean the aluminum pontoons on a pontoon boat. Works great to clean and brighten all sorts of aluminum (I have a pontoon boat). You can also use the spray foam air conditioner coil cleaner sold at Home Depot, Lowes, and just about any other home store or hardware store.
