What kind of car wash detergent should be used for a new car?
3 Answers
It is best to use a specialized car wash detergent for new cars. Dedicated car wash liquids are neutral cleaners that are gentle on both hands and paint, primarily composed of natural plant-derived surfactants. Precautions for car washing: After high-speed driving or prolonged exposure to intense sunlight, the surface temperature of the car paint becomes very high. If cold water is used to rinse at this time, the paint surface may be damaged, and in severe cases, it could lead to cracking. Frequency of car washing: There is no need to wash the car too frequently. Generally, washing the car once every 7-10 days is sufficient, as frequent washing can accelerate paint oxidation. However, this is not absolute. If the car body is contaminated with mud, rainwater, bird droppings, etc., the owner should clean the vehicle as soon as possible to prevent corrosion of the paint.
When I first got my new car, I made a point to research car wash soap. New car paint is much more delicate than older cars, so never take shortcuts by using household dish soap or soapy water—those contain high alkaline levels that can dull the paint and strip off protective wax layers after just a few washes. I recommend specialized pH-neutral car wash soaps, as they clean without damaging the paint and even add a bit of shine. It’s also best to avoid washing under direct sunlight to prevent water spots from quick evaporation. Regular use of proper car wash soap can reduce long-term maintenance hassles, saving you money on waxing and paint correction. New car owners should definitely give it a try—it’s easy to do yourself with a basic car wash kit.
As a DIY car washing enthusiast, it's essential to choose professional car shampoo for new vehicles. Ordinary dish soap leaves excessive residues that can corrode the paint surface, so I recommend using pH-neutral car shampoo with palm wax ingredients, which leaves a protective layer after washing. The washing method is equally important: adopt the two-bucket method - one bucket for shampoo solution and another with clean water to rinse the sponge, preventing scratches. Don't slack off during the first few months of ownership; thorough washing each time extends paint longevity. Pro tip: avoid directing high-pressure water jets into seams to prevent water intrusion risks. When purchasing car shampoo, don't compromise on quality - opt for reputable brands for peace of mind.
