To me depends on the parts.I clean my PC regularly but I am curious what is the best way to clean off baked dust as that never comes off when using compressed air?
I've not used anything else because of static being a concern.
So something like this?I use the above and for really dirty stuck on dust,I use a good OIL base paint brush. Sometimes called chip brushes.
Mode from pigs hair so it is non static building.
works wonders with compressed air.
