Washing Tips Oxidation (paint-starvation) occurs when paint loses its natural oils. Even the mildest soaps will accelerate this process. Commercial car washes with strong detergents can dull your car's finish even faster.
For years, Jaguar, Acura, Chrysler, BMW, Mercedes-Benz, Rolls Royce, Ferrari and most other fine automobile manufacturers have recommended using only plain cold water to wash your car. While this completely eliminates the damage soap can cause, it does not wash away surface contaminants.
The most important thing to be aware of when preparing to wash a car is the temperature of the car being washed. This is even more important than the ambient temperature, which should be between 50f and 80f. If the car has been in the sun for any time, it should be brought into the shade and allowed to cool off before dousing it with water. In addition, on recently driven cars, the brakes can be very hot, and if cold water gets onto the brake discs, they could warp. So get your car out of the garage and onto a flat, paved surface that is out of direct sunlight. Sunlight, as you know, turns drops of water into tiny lenses, burning the paint under them.
IMPORTANT: Remove your watch, rings and bracelet. Be alert to belt buckles, zippers and rivets on jeans. The first things to target are the wheels. If a car has a tendency to dust the front brakes with black pad residue, use Brite. Wet the wheels first, and then apply Brite. Allow the Brite to saturate the brake dust for a couple of minutes, and then work on the wheel with a brush and a fine spray of water to dislodge the dust. If necessary, apply a second coat of Brite; allow it to work for from two to five minutes Then repeat the process if necessary until the wheel is truly clean.
After the wheels are clean, mix some Clear in warm water in a Schpritzer bottle, soak each tyre and then scrub them with a detail brush. After the wheels and tyres are clean you can turn your attention to the lower body parts of the car. Apply a light mist of Clear and lightly wipe the panels with your hand as you rinse them off. This assures you that there is no sand or dirt on the car that might be picked up later by your sponge or towel.
After this is complete, use the hose with a fine spray to rinse the car from top to bottom. Include the doorjambs, bonnet and boot during the rinse. Use a mild solution of Clear in the Schpritzer bottle for the doorjambs, bonnet and boot edges.
Start the actual washing by working on one side of the roof, and then rinse it off. Finish the other side of the roof, and then wash all the windows, lifting the wipers and working all the way down to the front bumper. Using the hose during this step will get out any accumulations of dirt.
After the roof, then work on the bonnet. Wash one side, rinse it off, then wash and rinse the other side. Follow up with doing the boot the same way. After this is complete, work the entire upper portion of one side, one panel at a time. Rinse and re-soap as you go. It is a good idea to empty the soap bucket after you finish with the horizontal surfaces, then start with fresh soap for the upper sides. Please, use a drain; don't just dump the soapy water onto the ground. Even though Zymol products are environmentally safe, the dirt you remove from the car often is not.
Finish the wash sequence with the lower portions, including bumpers, grille and taillights. If this is the first time the car will receive the Zymol treatment, remove the license plates and the brackets to be sure the areas behind them will be properly prepared.
