I currently use 2 sponges (1 for upper parts of the car, 1 for side skirts, front and rear bumpers), 1 bucket for BMW shampoo, 2 Autoglym Aqua Dry (synthetic leather), Autoglym H-Tech Wheel Brush, BMW Wheel Rim Cleaner, and Karcher Jet Washer/hose. The steps are as follows:
(1) Spray BMW Wheel Rim Cleaner on the wheel, wait/rinse/brush/rinse until wheel is clean. Repeat the same process for other wheels;
(2) Wet the whole car, then use small paint brush to clean small areas with shampoo, e.g. front grilles, badges;
(3) Wash bonnet, bootlid, headlights, rear cluster lights, windows, windscreen and rear screen with sponge, then rinse;
(4) Wash front wings, door panels, rear wings, then rinse;
(5) Use the 2nd sponge to wash side skirts, front bumper, and rear bumper, then rinse;
(6) Rinse the whole car again from the top to the bottom;
(7) Dry the car with 1 Aqua Dry, and wheels with old Aqua Dry.
Advise me if I do anything wrong. What is the 2-bucket method? Do I need 2nd bucket for clean water if I use jet washer/hose to rinse?
