How do you cope with dust build up ?

Over the years I am constantly battling dust build up. Although I dust with feather duster, there are places that you cannot get to unless you disconnect equipment and or move equipment ( in my case very difficult to do).
I'm pretty sure that the dust build-up is a major problem with equipment. It gets into the cases, on the drivers, on the connections.. pretty much everywhere.
What do most of you do about this?
My LP collection suffers same fate and it's in a cabinet..
Not a sealed cabinet however. Yes the Lp's are in sealed covers( mostly) but dust builds up on covers etc.
Any suggestions?
