This snow foaming thing. ..... Mixing is the key for better cleansing and less chance of it drying on the panels, bilt hamber snow foam is perfect for the summer months, as well being great at cleansing, it's not a high foamer and being so slides off the car giving it less time to dry out on the panels.
In the winter months l use valet pro Advanced snow foam, it has deeper cleaning abilities and foams up like no other ideal for staying on the panels longer but
I prefer a runny mixture ie a mix you can hear plopping off onto the ground ..... These cars with the Xmas card look may look impressive but in reality the mix is more than likely too strong
Valet pro citrus pre wash, l used a 5 litre bottle through the winter months this year and to be honest l didn't see it cleaning any better than the snow foam l use, so l won't be buying it again.
And l ask myself now and again are these snowfoams really worth it ... "Placebo effect" As just blasting away the dirt off your car with a pressure washer can give similar results
