What Can Be Used as a Substitute for Car Wash Soap?
2 Answers
In the absence of car wash soap, neutral dishwashing liquid can be used as a substitute. Some car washes use laundry detergent, but cheap bulk dishwashing liquid can cause significant damage to the paint. The main cleaning ingredients in car wash soap are natural plant-derived surfactants, which are also the primary components of domestic shampoos. Additionally, car wash soap usually contains natural car wax and ingredients that naturally eliminate static electricity from the vehicle body. It is not recommended to use laundry detergent for a long time because it is an alkaline detergent that can severely damage the car's paint. If laundry detergent is used to wash the car over an extended period, the car's surface will gradually lose its shine. Dishwashing liquid, while effective in removing stains, also has a wax-stripping effect, which over time will cause the car's paint to lose its luster.
I think if you run out of car wash soap, you can easily find substitutes at home, like mild dish soap or laundry detergent. Dish soap effectively removes oil and dust from the car body, but make sure to choose one without bleach, as long-term use can damage the paint. It’s also best to dilute it with water, about a 1:1 ratio, so it doesn’t feel too sticky when scrubbing. Shampoo is also a reliable option, especially for oily stains, and leaves a light fragrance, making the car feel fresher. Just rinsing with water works too—it’s fine for mud and loose dirt, though it’s less effective against stubborn stains. I often use these methods for quick weekend car washes—it’s convenient and saves money. Just remember to rinse thoroughly to avoid residue damaging the car’s surface. Simple and practical!
