I was using my shop vac in blow mode. But it seems I never go all the dust out of the hose, and it would blow some dust. So now, I use my electric leaf blower. Of course, I always get really strange looks from my neighbors.
IMHO, I would be hesitant to use an air compressor, as I think the concentrated air blast could force water in places you don't want it. Just MHO...your mileage may vary.
The heated air dryers are nice but a little to pricey.I use my electric leaf blower to get most of the water off,followed by a soft towel for the remainder of spots.
