After washing your car, let the water flow heavily over the car. The water will sheet off and it will be much easier to dry as well as help avoid water spots.
Recommended: Heavy flowing water will help the excess water dissipate faster, making it easier for drying.
More quick wash tips:
• Don’t skimp on your wash mitt. If it is getting old or dirty, replace it. The cost of a mitt is not worth the time and labor to remove swirl marks in your paint.
• To avoid swirls, only use quality microfiber towels for cleaning and drying. Never use terrycloth, diapers or t-shirts.
