Can laundry detergent be used to wash a car?

[DakotaLee]

It is not recommended to use dishwashing liquid to wash a car because: Car wash solutions generally have a pH value of 7-8, which is neutral. Dishwashing liquid is also neutral, so using it to wash a car should not cause any damage. However, the foaming ability and lubricity of dishwashing liquid are far inferior to those of car wash solutions, so it is still not advisable to use dishwashing liquid for car washing. For an ordinary car, it doesn't make much difference what you use to wash it. But for a high-end car, if you particularly cherish your vehicle or want to avoid potential damage, it's better to choose a neutral, environmentally friendly detergent. Car wash towels should be categorized and not used indiscriminately. Towels used to wipe the lower part of the car body contain a large amount of fine sand that cannot be washed off, and such towels can easily scratch the car's paint.
