This is my basic wash, quick and easy. Hopefully, someone will tell me if something is dramatically wrong. I haven't seen any damage or downside in a year. Go to a self-wash and use pressure washer on everything that is blue. Avoid the other stuff. About four minutes of high pressure wash guarantees me there is no sand or grit left anywhere, just stuck-on fine dust is left behind. Meguiar's Ultimate Wash & Wax applied and rubbed in (no circles!) with a Wookiee-looking green mitten-you know the type. Then a rinse. Then spray Meguiar's Ultimate Quik Wax on a panel, then use a LARGE microfiber towel to simultaneously dry and spread the spray-on wax evenly. After drying the whole car with the soaked LARGE miccrofiber towel, I begin getting it really dry with small microfiber towels. Spraying the Quik Wax on any spots I see to remove them. Work from top to bottom, cuz it's always dirtiest on bottom. Don't use car rags on tires or vice versa.
