pressure washer or bucket and sponge?

[sawman]

Typically cleaning the car for me involves buckets, sponges and mitt, using autoglym shampoo and the occasional super resin polish and once a year HD cleanse and wax all by hand.

I have recently acquired a karcher pressure washer (it came with the garage of the house we are renting) . and I wonder if snowfoaming might be an improvement on the start of my washing ritual.

Any thoughts/tips or recommendations on products? I have just read that bilthamber products scored well in an auto express test
