What soap are you using with your foam guns?

Just a little curious as to what everyone is using as far as a soap with the foam guns.

I'm still experimenting with my foam gun. Right now, I'm using a 50/50 mix of PB's Bug Squash and Super Slick & Suds. This solution combines two steps into one: a Bug Squash pre-wash (for loosening up massive road salt build-up) plus the sudsing and clean rinsing qualities of SS&S. If a pre-wash isn't needed, I use a 50/50 mixture of water with SS&S.
