I really need to look into the fully ONR offering as currently no hose option as inbetween houses.
My fortnightly wash method involves the local Tesco jetwash:
- Snow foam user my hand Foamer and Bilt Hamber AF and Korrosol on the wheels
- Rinse with pressure/cold shampoo
- Hot foam brush - don't touch the car but drip this over so the whole car covered in shampoo
- Wash mitt hand wash
- Cold rinse
- Dry using Aquawax and microfibres
Works pretty well and can manage it with 2 or sometimes 3 £1 credits in the machine
