^ awesome reply!
Just a couple other things, try and get a good wash mitt. This will make the world of difference in protecting the car. For the interior, you can use Cockpit Premium or 303. I like both honestly but 303 is a 2 step.
-Clean wheels first to avoid getting it on the car
-Use a blower to help dry the car (helps with crack and excess water. Got mine for $25 a home depot)
-Do both the Rejuv. Oil and PC for the leather, leather will feel very clean.
-Try collinite as a second layer of protection on top of the sealant (optional but i love collinite
Hope this helps
