Which items should never be used during a vehicle wash?
Cleaning your car seems like a simple weekend task, but using the wrong supplies can lead to permanent paint damage. Many common household items are too aggressive for automotive finishes. To keep your car looking new and to protect its resale value, avoid these common mistakes.
Stop using dish soap
It is a common myth that dishwashing detergent is a good substitute for car soap. In reality, dish soap is designed to strip away grease and food from ceramic plates. When you use it on a vehicle, it strips away the protective wax and sealants that keep your paint safe from the sun and road salt. Over time, this leaves your clear coat exposed and can lead to a dull, faded look. Always use a dedicated car wash soap that is pH-balanced to safely lift dirt without removing protection.
Skip the car wash brush
Many self-serve stations provide a large scrubbing brush. While they are convenient, these brushes often hold onto rocks and grit from the muddy trucks that used them before you. Using these on your paint is like rubbing sandpaper over your car. If you want to keep your finish smooth, only use those brushes for your wheels and rims. For the body of the car, a soft microfiber wash mitt is a much safer choice.
Avoid hot water
You might think hot water cleans better, but high temperatures can actually be hard on your car. Extreme heat can cause plastic trim pieces to warp or degrade over time. It is always best to use cool or room temperature water. This is safer for the delicate sensors and plastic components found on modern vehicles.
Is a magic eraser safe for car paint?
You should never use a magic eraser to remove scuffs or stains from your car’s exterior. These erasers are actually made of a very fine abrasive foam. Using one on your paint will quickly sand down the clear coat and leave a hazy, scratched patch that often requires professional repair to fix.
A note on DIY “Quick Fixes”
When you are trying to fix a small spot, you might be tempted to use whatever is in your cabinet. For example, some people try to hide scratches with nail polish. This is a mistake that can actually lower your trade-in value because it is very easy for buyers to spot. If you want to maintain your investment, stick to professional products or services.
