+1 for Bilt Hamber Auto Foam
I also have a bottle of Autobrite Magifoam that came with my Autobrite Direct snow foam lance. It's supposed to be decent stuff but as of yet I've not got round to trying it because I'm more than happy with the Bilt Hamber foam.
AD magifoam is the worst i've tried imho! yes it clings to the car and thats about as good as it got for me, was absolutely dire at cleaning and stayed on the drive for days after every use or until washed away! also known for clogging lance gauzes up due to the amount of soap fats in it and even rinsing my bottle with hot water every use i had to replace/clean the gauze yearly and it got that bad i gave 5l of it away!
OK. Maybe I'll pour it down the sink then. Actually, maybe that's not a good idea based on what you just said Maybe I'll give it away to someone I don't like I got it free anyway as part of a promotion so thankfully I haven't thrown away good money.
meguairs hyper wash works well as a snow foam. 200ml in a 1ltr snow foam gun and your good to go.
how much?!?! you must be loaded to justify that haha!
