You can just skip the towel dry step if you wash/rinse with filtered water.
I've been using the car wash for maintenance washing to get big crap off, but frankly no amount of water pressure measures up to just taking your MF mitt and wiping it once. So that's great, but if you do it at home you then have to towel dry which is a) a pain in the ass b) nearly impossible in the desert where water dries instantly c) uses a ton of towels
I started looking up water filtration and additives to prevent hard water spots, and it's all complicated or expensive. Then I noticed my grocery store sells reverse osmosis water for 30 cents/gallon. Just buy 5 gallons for $1.80, which I can wash my car like 3 times for, and enjoy the air-dry lifestyle.
