Hi! I'm still a bit confused about degreasing - whether it needs to be done before using shampoo, exactly what gets degreased (just tyres or paint as well), and which degreasers are safe to use on paint. I would really welcome contributions on this topic. Thanks!
I like to degrease after an initial rinse with my pressure washer and before foaming the vehicle down. I usually use a mixture of CWC, Strong Wash and/or MS SGS in the foam cannon as well.
