Dish Soap vs Car Soap – What’s the Difference?

A common beginner mistake is grabbing a bottle of dish soap to wash a car. After all, soap is soap, right? Not exactly. While dish soap might seem like a cheap alternative, it can actually strip away protection and damage your car’s finish. Let’s break down the differences between dish soap and dedicated car wash soap so you know which one to use.

Why People Use Dish Soap on Cars

Many beginners choose dish soap because it’s cheap, widely available, and makes suds. Some even like that it cuts through grease and grime quickly. But here’s the catch: dish soap is designed for kitchenware, not automotive paint.

The Problem with Dish Soap

  • Strips protection: Dish soap is formulated to remove oils and grease. On cars, this means it strips wax, sealants, and ceramic sprays.
  • Harsh on finishes: It can dry out rubber, plastic, and trim.
  • Low lubrication: Dish soap doesn’t provide the slickness needed to safely glide dirt off paint, which increases the risk of swirl marks.

Why Car Wash Soap Is Different

A dedicated car soap like The Super Soaper is specifically designed for automotive finishes. Here’s what sets it apart:

  • pH-balanced: Safe on waxes, sealants, and ceramic coatings.
  • High lubrication: Dirt glides off instead of grinding into paint.
  • Foam-rich: Creates a thick pre-soak layer that loosens grime before contact washing.
  • Safe for trim: Won’t dry out rubber, plastics, or vinyl.

When Dish Soap Might Be Useful

There is one scenario where dish soap can be used intentionally: stripping old wax. If you plan to polish or apply a ceramic coating, dish soap can remove existing waxes and oils. However, a dedicated panel prep product is safer and more effective.
