Did my 3rd Rinseless wash yesterday and I'm absolutely hooked. Glen E gave me some excellent advice. Also enjoyed Gary Dean's video and tips. If done correctly, I absolutely believe rinseless washing is safer than a traditional wash, unless the car is super caked with dirt.
My best advice:
1. Use top quality microfiber towels...I use Adams double soft...can't say enough good things about them...expensive and totally worth it
2. Use a top quality waffle drying towel...get at least 2...never tried them until recently & can't imagine living without them now
3. Get a $20 garden sprayer and fill with about a gallon of wash solution to pre-treat the panels
4. Use a finishing spray before wiping away the water...allows the towel to glide more easily...might enhance gloss, too
As far as my routine, I don't rinse and reuse towels. I use one side until it gets lightly soiled, then I flip it. Once both sides are used, it goes in a dirty towel bucket to be cleaned in the washing machine. Never scrub or use more than light pressure...let the wash solution do its job. Wash the car in sections, moving from top surfaces to bottom.
Finally, have fun!
