A pressure washer (sometimes called a water blaster) might seem like an easy way to wash your car, but it can actually cause more harm than good. While it removes dirt fast, it can also damage your paint, cause scratches, and even lead to rust.
Here’s why we don’t recommend using a pressure washer on your car — and what you should do instead.
The high pressure can strip away your car’s clear coat or even chip the paint if used too close. Once the paint is damaged, it becomes easier for scratches, rust, and fading to start.
If your car already has small scratches or swirl marks, blasting it with a pressure washer can make them deeper or more visible. We often get calls for car scratch repair after months of improper washing.
Pressure washers can push water into your car’s door seals, windows, and sensors. Over time, this can cause leaks, foggy lights, or even electrical issues.
Dirt should be gently lifted using a soft mitt and car shampoo. A pressure washer just pushes dirt around at high speed — which can grind grit into the paint and cause micro-scratches.
This method protects your paint and helps avoid the need for future car scratch repair.
Pressure washers are great for cleaning driveways — not for car paint. They can damage your car more than they help, especially if used incorrectly.
