Wax on, Wax off.
This is when I like to use Dawn before a full detail (and only before a full detail). But, if I feel that the vehicle doesn't have much wax on it anyways, which should be the case if you're doing a full detail anyways, than I'll go on with my 'standard' wash and than proceed to clay.
What do you like to use for a regular wash?
I'm in love with Chemical Guys Maxi-Suds II, myself. It works great for foam with the gun and excellent in a bucket, too. It won't strip wax or sealant either and smells fucking great.
