Powder used for fingerprinting are extremely fine. They work by sticking to the organic materials which are in the suspect's sweat when they touch an object.
DO NOT USE ANYTHING MOIST TO WIPE OFF THE POWDER. It will create a kind of paste or tacky paint. Instead, use a dry cloth or dry paper towel to try and collect as much of the powder as possible.
After you do that, if you have any kind of handheld vacuum try giving that a shot. Once you are satisfied that you have collected as much powder as possible using dry paper towels/cloths, then you can go ahead and use a damp cloth to wipe off the surface. But remember, do this AFTER you have used dry cloth or towels.
