What to use when drying off car after wash?
I have been using the same chamois for the last twenty years or so. When I'm done with it, I run it through the rinse cycle only of the wash and then fold it nicely on top of the dryer. When it's dry, I put it back in a small box that I keep in my trunk. It's nice to have at shows in case of a pop up shower.
At work (customer cars), we have silicon squeegees that work well, and then follow up with a microfiber. I also vote for the Costco brand microfibers. They are cheap but the quality is great. I've got one I keep right here at the computer to clean my glasses every morning.
