i was wondering what you guys thought of washing your car duster... the directions state : " the dirtier the duster gets the better it works", "but you can wash it if you want".... the nap is 1 to 1 1/2 deep, and their is some kind of wax or something on it to pick the dust up instead of smearing it around ( i'm sure you guys know what i'm talking about) if i wash it, wont that take the stuff off that picks up the dust ??? should i just shake it out ?? i dont want to marr the vehicle, the company claims it wont scratch, i think its the same company that makes the california water blade.. thanks
