I wash my car with blue dawn dish soap or something high in ammonia. Then I use a meguiars clay bar kit then I wash it with blue dawn again. Then I use a product made by blue coral for professional detailling called SEALTEK to paint seal the paint. Then I do 2 coats of meguiars NXT (or your favorite synthetic wax) then 2 coats of Meguiars Gold Class (or your favorite carnuba wax). Then I would simply wipe down my car with a microfiber towell, and if it gets a tad dirty I use meguiars NXT quick detail. After all that I wash it once in awhile with Meguiars Gold Class car shampoo.
