Dusting tube amp


I know a lot of people recommend canned air, which I will use as step two, but I worry about blowing dust into the amp.

Does anyone use a small duster like a swiffer to dust the surface of the amp and maybe run lightly over and around the tubes to remove dust?

Try a small paint brush approximately 1 inch wide. Brush the dusty areas while holding a vacuum cleaner hose directly over the area being dusted. No dust will go inside of your amp using this method.

The vacuum technique is an excellent idea. To take it a step further, have it performed by your personal french maid. Or in Elizabeth's case, personal pool boy.
