Keeping your components Dust Free

If you feel anxious and the equipment is vented (holes or slots on the top of the case), just remove the top cover every few years and vacuum the dust out.  Make sure you unplug first!  If equipment isn't vented, don't worry about it; it'll be cleaned if you ever have to have it serviced.

I use a natural China bristle paint brush lightly sprayed with Pledge all surface dusting fluid to get in the nooks and crannies.  It is as soft as a make up brush but much larger.

Keeping dust covers over all my gear and speakers always, except when listening

I cover the vents on all of my gear with a piece of suede fabric to keep the dust out  and I remove it when the component is in use..

I still do most of the things that have been mentioned by others, including taking the top of the component every year or two.
