Air dryers aren't for everyone's wallet, but there are other alternatives that are way friendlier to anyone's budget. That's why we need to talk about The Absorber. This is a synthetic chamois drying towel product from CleanTools that does a downright amazing job.
You can use the chamois like a cotton towel to dry off areas of the car, or spread it across a larger part of the car like the roof or hood and drag it to suck up water left without swirl marks after a car wash. In both instances, the absorbency of the chamois cloth leaves a nearly dry surface that should take just a few minutes to totally clear up before you move on to claying, wax or calling it a day.
The Absorber makes drying the car a simple process and it should be on your shopping list.
