Washing your car is important. It keeps your car clean and shiny. But, many people do not know what kind of soap to use. Using the wrong soap can hurt your car’s paint. So, it is good to know which soap is best.
Why Use Soap to Wash Your Car?

But not all soaps are the same. Some soaps are too strong. They can damage the paint or make it dull. So, choosing the right soap is very important.
Can You Use Dish Soap to Wash Your Car?
Many people use dish soap to wash cars. It is easy to find and cheap. But dish soap is made for dishes, not cars. It can remove oils that protect your car’s paint. This can make the paint dry and crack over time.

So, it is better to avoid dish soap for car washing.
