Since using BH Snow Foam I notice that there are 'spots' left on the car where the car dries before I can get round with my wask mitt etc.
Routine:-
BH Snow Foam - set so that 4% dilution rate applies via pressure washer
Leave 5 mins
Rinse off with pressure washer
Start washing car with mitt and bucket
It's when I get round to the final part of the car, say 20 - 25 mins after the rinse, that I see the 'dried' spots. It was worse yesterday as it was quite sunny
