CAN I USE TOWELS TO DRY MY CAR?
For the most part any towel can be used to dry your car, but not all towels can get it dry without leaving swirl marks. Clean chamois, 100% cotton terry cloth and microfiber cloth are the safest towels to use for car care, as they've been tested to treat your finish without creating abrasions.
When you use an old t-shirt, shop rag or cloth diaper, you're risking abrasions with towels that may have embedded dirt particles. They may be of a fabric blend that's not soft on your paint. The best way to dry your car and minimize the risk of scratches is to get a set of safe towels that you keep clean and separate from the rest of your rags.
