Car Cleaning Myth: Dish washing detergent is the best car wash

Well, I guess this would be true if you want to wax and dress your tires and trim after every wash. You see, dish washing liquids, like Dawn dish detergent, are designed to remove oils, grease, food, etc., and they do a great job. They also do a good job removing waxes, polymers and silicone. That's why this myth is debunked. For best results, always use a pH balanced car wash soap or shampoo with glossing conditioners.
