I know this thread is a bit old, but thought I'd throw in my two cents. I'm a bit of a fanatic when it comes to cleaning my car. As hydbob said, you can spend a lot of money on this! I have a Kranzle pressure washer, a foam cannon, lots of chemicals, clay bars and microfiber towel, heck, I even have an 8ph warm filtered air car dryer and a wall mounted garage vacuum! I know, I'm an idiot, but with the kids grown I have more time on the weekends. I will say that my favorite drying towel is the Luxury Microfiber Sucker drying towel. This thing is amazing and I highly recommend it. If you want to go down a rabbit hole on this topic, there's a professional car detailing guy out of Canada who has an awesome YouTube channel with all kinds of helpful information. His name is Pan the Organizer and he has tons of content.
