also depends on which snow foam you are using? some are just a foam that pretty much do nothing, stuff like the AB magifoam etc does a great deal and lifts a huge amount of dirt
like has been said before snow foam is only a PRE wash not a alternative for washing or a good cleaner. it does make washing the car with a mit SO much easier though. did you not jet wash the car first before snow foaming?
Yes that was my point, I was just doing a little experiment to prove it. No, I find the snow foam works better putting it on a dry car.
Use Autofinnese avalanche, doesn't cling for very long which is the reason I don't jet wash first, seems to stick a bit better on the dry. It does however seem to do the job, I'll probably try a different kind when its done though.
This is good to know as I just got Autofinesse Avalanche and the AutoBrite snow foam lance last week but haven't yet tried them. Hopefully I'll have time this weekend, I looking forward having ago with the foam lance as I've never used one before.
Report back with how you get on! The lack of thick foam and cling could well be down to me!
