I’m sure you’ve seen plenty of older generations just using dish soap to wash their car. In this post, I’ll show you whether dish soap is good for washing cars, and what’s a better alternative.

Key Takeaways:

  • Dish soaps are bad for your vehicle and will cause the paint to look dull and oxidize quicker.
  • Dish soaps shouldn’t be used to wash your car unless you’re using them to remove old waxes and sealants.
  • Always use dedicated automotive soaps that will allow you to gently remove all the dirt and grime from the car.

Can You Use Dish Soap To Wash a Car?

You shouldn’t use dish soap to wash a car. Dish soap ingredients can do more harm than good to your vehicle’s finish, and in almost all cases, using dish soaps should be avoided altogether.

Few reasons why I don’t recommend you use dish soaps to wash your vehicles:

  • Dish soaps aren’t made for cars. They’re intended to use for greasy dishes, thus being too aggressive for the car’s paint.
  • Dish soaps will strip waxes and sealants. Washing your car with dish soap causes waxes and sealants to wear quicker and leave your car’s finish unprotected.
  • Bad lubrication properties. All high-quality automotive shampoos have great lubrication properties, which isn’t the case with dish soaps. Without enough lubrication, you’ll cause swirl marks and scratches on your vehicle while washing it.
  • Causing the car’s paint to oxidize. If you constantly use dish soap to wash your car, they’ll cause the paint to oxidize quicker.

When You Can Use Dish Soaps For Washing Cars

Even though I never recommend using dish soaps, they can be effective at removing old waxes and sealants.

Washing your car with dish soap will strip old waxes and sealants so that you can apply new protection to the car’s paint.

However, the best option is to buy a specialized pre-wax cleaner. It will permanently remove waxes and sealants, while dish soaps may not.

What Soap To Use To Wash Your Car?

I hope that by now, you already know that you shouldn’t use dish soap or any other non-car soap (hand soap, etc.).

It would be best if you always used a high-quality pH-neutral car washing soap. My recommendation is Meguiar’s Gold Class Car Wash Soap and Conditioner.

It creates a foam that removes all the dirt and grime without removing waxes and sealants away from the car’s paint.

Of course, it’s not the only high-quality car wash shampoo. You can check other best car wash shampoos here.

Key differences between car wash soap and a dish soap

You see how many important differences are there. That’s the reason why you should always use car shampoos instead of any other type of soap.

Why Do People Still Use Dish Soaps To Wash Their Cars?

Well, I think that the lack of knowledge is the main reason for that. Many people don’t educate themselves enough.

Also, some people use it when they’re in a rush, and they don’t have any of the car products at home but still want to clean their cars. 

I can’t entirely agree with that too. Nothing will happen if you don’t wash your car for two days more until some car wash soap arrives. Also, you can buy car wash soaps in almost any more extensive shop.

Even the cheapest car wash soaps (that are pH-neutral) are better to use than dish soap. At least, they’ll be easy to rinse off, which is not the situation with dish soap (check the table above).
