If you have to get the junk out from under components, a
vacuum cleaner just doesn't work. However, an air gun with 100psi
behind it will remove the dust and probably some of the paint.

As will the same gun with anything over 13 PSIg... which is high
enough to produce a sonic flow... any higher pressure will give
more massflow, being the same velocity at higher density... but
the cleaning effect doesn't increase much... unless your nozzle
has a CD orifice to produce a supersonic flow.
