Firstly I use valet pro citrus pre wash (amazing stuff)
Spray on with a pumpy pressure sprayer Leave to soak on for 5 mins then quick rinse off with hose or jet wash from a distance
Then its 2 bucket wash method with meguiars gold class and meguiars lambs wool mitt, (clean wheels last with an older mitt i have)
Followed by good rinse off then use an open ended hose to sheet the water off car which preety much dries it too
Quick 5 mins of final drying with my giant micro fibre towel and some poor boys quick detailer and im done
Whole process takes about 45 mins and results are spot on
Water sheeting drying method will only work on a well waxed car, i give mine a good waxing every couple months with Autoglym Hd wax as like to keep her minty condition
Not the cheapest products but gives great results and offers great paint protection plus i really enjoy cleaning my car every other Saturday morning
