Tips for Washing your Car

What is the best product to use as a car wash? The correct answer is use what you like the best. There are some drawbacks to certain products and advantages to others. Dish detergents (Ivory Liquid, etc.) may be used, but realize that these products are designed to remove animal or vegetable fat from fired ceramic. They look at your nice coat of wax with the same hungry eyes. If you enjoy washing and rewaxing weekly, then dish detergent is for you. Wax retailers love people who use Ivory Liquid (they send the Ivory Company Christmas Cards every year). 

If you prefer to have your wax last a lot longer, you may consider using a product that is specifically designed for automotive use. The quality products are based upon detergents instead of soaps. Most soaps are manufactured from rendered animal byproducts (the stuff the dog food people reject). They contain trace elements that can actually damage your paint. These trace elements are the same goodies that leave a ring in your bathtub. The exception is soaps manufactured from plant fats. (These leave mold in your tub - just Kidding)

Quality car washes/shampoos (same thing - most cars don't have hair) are usually pH controlled, contain gloss enhancers and some even have small amounts of water-soluble wax for good measure. Use only enough car wash to break the electrostatic/ionic bond between the dirt and your car. Start with a clean large bucket (preferably plastic - if you kick the metal bucket, Mr. Paint Chip rears his ugly head); add a small amount of the car wash and fill with cool water. Avoid hot water, as it will soften the wax. Read the directions on the car wash bottle and try reducing the recommended amount by half. I use less than a cap full in 5 gallons. The more car wash, the more wax you remove. Try to avoid powder car washes as the undissolved granules can lodge under your sponge or wash mitt and scratch the paint surface. Make sure that your car is in the shade and the paint surface is relatively cool. Rule of thumb #1: If you can comfortably hold your hand on the hood, you can wash/wax the car.

Spray the car with a gentle spray to thoroughly wet the surface. Don't use a 200 P.S.I. fire hydrant spray, it isn't needed and may grind the surface grime into the paint and cause scratches. Some of the concours purists will not use a nozzle on the hose at all. Start at the top of the car and work down. Rewet the top; gently wash the top and then rinse. Move onto another section, such as the trunk or hood. Rewet this area, wash and rinse. Continue on down the car, completing a section at a time. This way, the car wash does not dry on the paint.
