Why Do People Use Dish Soap for Cars?
- Dish soap is cheap and easy to find.
- It cleans dirt and grease well.
- People think it can do the same on cars.
- It makes lots of foam, so it looks like it cleans good.
The Problem with Dish Soap on Cars
Dish soap is strong. It removes grease on dishes but can harm your car’s paint. Car paint has a special layer called clear coat. This layer protects the paint underneath from sun, rain, and dirt.
Dish soap can strip away this clear coat. This means your car paint may fade or get damaged faster. The paint may lose shine and look dull. Over time, small scratches and cracks can appear.
Also, dish soap can dry out the rubber parts on your car. It can make tires and seals crack or become weak. This can cause more damage and cost you money to fix later.

What Happens If You Use Dish Soap Once?
If you use dish soap one time, your car may not get much harm. But using it often is not good. The damage comes from many washes over time.
Think of it like this: washing your car with dish soap is like washing your hair with dish soap. One time is okay, but doing it every day can hurt your hair. The same goes for your car.
What Should You Use Instead of Dish Soap?
It is better to use soap made for cars. These soaps clean dirt but are gentle on paint and rubber. They keep your car safe and shiny for a long time.
Car soaps are easy to find. They do not cost much more than dish soap. They are made to protect your car’s surface.
