I've heard of the 2 bucket method but not 3
What sort of budget do you want to work too? I'll list some products and then you can tell me if they are too cheap or expensive.
Wash
Shampoo - Dodo Juice Born to be Mild - £8.95 for 250ml or £16.95 for 500ml
Mitt - Dodo Juice Tribble Mitt - £8.95 or Meg's Lambswool for £9.95
Drying Towel - Waxamomo Deep Pile Towel - £10.95
Polish - Dodo Juice Lime Prime - £12.95 for 250ml or Poorboy's Professional Polish £13.95 (how bad does it need a polish?)
Applicator - Lake Country Polish Hand Applicator - £3.95
Wax - Depends on budget, any Dodo, Collinite, Meg's or Chemical Guys
I can add more products like glass clean, wheel cleaner, interior cleaner, dressings etc etc if you really want me too
Let me know what you think and I will adjust the list for you.
