Couldn't agree more - I must look into filtration tooHello Fast Freddie,
I also use a pre wash snow foam but only when it is caked in grime and when the car is able to stay wet. I am sure that you are already aware but I have noticed that it can leave marks if it either drys on or isn't thoroughly rinsed off.
Also, because we live in a hard water area, I also do a finish rinse using filtered water. I filter it through a meter long inline filter. It leaves the van in a good state for toweling off. Less water marks and easy to get a spot free finish. The trouble with these filters is that they are expensive, degrade quickly if exposed to direct sunlight and don't last that long. It might sound rather fussy but calcium water marks can be difficult to shift especially on dark paint colours.
