Dry with a low scratch risk towel, we recommend the Rockcar Performer Drying towel.
You want to remove all the water to avoid water spots. You also want to ensure in drying you dont scratch the car.
One option is to use an air dryer or blower, the issue here is not all of the water is blown off, some of it evaporates and leaves the minerals in the water behind which like mini water spots dulls your paint over time.
Instead we recommend using a drying towel, but a good drying towel. So what do we mean buy that, what do you want in a drying towel?
First you want it to be a 70:30 blend microfiber cloth, that is 70% polyester and 30% polyamide, that is the sweet spot for structure, absorbency and softness. Polyamide is expensive so most drying towels are only 20%, 10%, 5% or 0% polyamide, it makes it a lot cheaper to manufacture. Don't use those.
Most important is you want realy long strands. This is so if there is any dust, dirt or grit missed or that lands from the air after the wash, that there is somewhere for this to go other than being dragged across the paint. A good way to visualise this is to imagine a polished wooden table, sprinkle some sand on it, then put something flat like a book on it and move the book. It will scratch. The sand has nowhere to go but down and accross the wood as the book is flat. It's the same when drying a car. If you use something flat like a chamois, or even worse a drying blade, and you have any tiny piece of dirt, grit or dust on the car, it will be dragged across and down into your paint and it will scratch. Instead sue something that's not just 70:30 blend but that has a long weave so that any grit has somewhere to go and not just dragged across the surface of the paint.
And last, you want absorbency. You want to dry the car quickly and easily, not just smear water around.
Pro Tip add shine while drying:
If you are doing a regular maintenance wash and not going to clay and polish the car, a great time saver is to use the Autostolz Enhanced Spray Wax as a drying aid. Spray the Autostolz onto the wet car as you dry, section at a time, and buff it off as you dry with the Rockcar performer Towel. In next to no time you have addead a layer of SiO2 and Carnaubra wax while drying, addign amazing shine, water beading and protection. if you do this with every wash you'll keep up the protection and your car will get easier and easier to clean as the layers build on each other.
