Avoid Dealership Car Washes—Unless You Want This Damage

The Hidden Dangers of Dealership Car Washes

Every day, car owners bring their vehicles into dealerships for routine maintenance or repairs. Whether it's an oil change, a tire rotation, or just a quick check-up, the process usually involves handing over the keys and waiting in the lobby. But what many don't realize is that this seemingly harmless step can lead to unexpected damage—especially when it comes to the dealership’s wash.

A recent TikTok video from a New Jersey-based detailing and custom shop highlighted this issue after the shop owner forgot to tell a dealership not to wash his vehicle. The result? Visible swirl marks on the driver’s side door after just one wash. One single wash was enough to mar the paint, leaving the owner visibly upset.

While some viewers questioned the timing of the warning—given that the person posting is in the detailing business—the concern raised is valid. Anyone who cares about their car’s appearance knows that swirl marks are a real problem. These fine, circular scratches may seem minor, but they can significantly dull the finish of a car, especially on dark-colored vehicles.

Why Dealership Washes Can Be a Problem

The issue isn’t necessarily malicious intent, but rather the speed and volume at which dealerships operate. Service departments often handle dozens of cars each day, with speed being the top priority. This means that brushes, mitts, and towels aren’t always properly cleaned between vehicles, leading to contamination and potential damage.

Additionally, the staff performing these washes are typically service technicians or lot attendants, not professional detailers. They’re trained to move cars quickly through the process, not to preserve the paint. Aging equipment that isn’t cleaned or replaced regularly can also contribute to the problem. Automatic wash systems, in particular, can be problematic if the brushes are worn and dragging across the clear coat.

The Internet Chimes In (As It Does)

The TikTok video sparked a wave of responses from users who had similar experiences with dealership washes. One commenter shared a story about a Volkswagen dealership that “destroyed” their Tiguan. Another viewer immediately recognized the cause of the swirl marks, calling out the use of a “noodle slapper”—a term used to describe the soft hanging strips in automatic car washes that can be extremely damaging when loaded with grime.

Many commenters shared their own strategies for avoiding dealership washes altogether. Some said they never allow dealerships to wash their vehicles, even their daily drivers or trucks. Others preferred to hand-wash their cars at home or take them to a professional detailer who truly understands the importance of proper technique.

While not all dealerships are the same, the experience can vary widely. Some luxury brand dealerships do offer hand-washes and detailed services after every visit, but this isn’t the norm. The unpredictability of the process makes it a risk that many car owners would rather avoid.

What You Can Actually Do About It

The solution is surprisingly simple: just tell them not to wash your car. When you drop off your vehicle for service, make sure to say those exact words. Most dealerships are happy to skip the wash, as it saves time and resources. If you want your car clean, consider doing it yourself at home with a proper two-bucket hand wash or taking it to a professional detailer.

For those who keep their cars detailed, ceramic coated, or simply enjoy a clean finish without the micro-scratch souvenir, this small step can make a big difference. It only takes a few seconds to mention at drop-off, and it can prevent unnecessary damage and regret.

If you’ve already forgotten to say it and come back to a car full of swirl marks, you’re not alone. Welcome to the club. It’s a big club, and while there’s no secret handshake, there’s definitely a lot of polishing compound involved.
