If you wash your car yourself & haven’t discovered waffle weave microfiber towels, you need to check them out. A single large (usually between 24″ x 30″ and 25″ x 36″) towel is enough to dry a small to midsize car. Two of them – one per hand – will easily dry an SUV. Plus… they won’t scratch your paint unlike cheap cotton towels or that rag you have lying on your workbench.
If you’re a golfer, throw one in your bag – if you’re caught in the rain, they’re superb at drying grips, the seat on your cart, etc.
There are a variety of sources and prices. I’ve purchased from both Autopia and Detailers Paradise and have received great service from both. As always, I have no connection to either of these suppliers other than being a customer.
