Anyone use snow foam on their car?

[JohnnyMcGrathSaysFuckOff]

We have just brought home a new car. The old car got washed about once a month with Autoglym or whatever car shampoo was on offer in the supermarket.

But a guy down the street uses snow foam and his car looks great. If you use it, can you talk me through it in short words?

My DH washes his car with snow foam (not mine, it is the poor relative 😂) - he attaches the bottle to the pressure washer. He probably secretly bought another attachment for the pressure washer.

There's loads of YouTube tutorials- I can't remember if he rinses before/after etc and I don't want to ask in case he thinks I'm interested!
