I Tried 10 Car Washes in Miami - Here's What I Found (And Why I'll Never Go Back)
I've been detailing cars professionally in Miami for years, and I've always heard the same complaints from new clients. They tell me their paint looks dull, they're seeing swirl marks under the sun, or their car just doesn't shine like it used to. When I ask where they've been getting their car washed, the answer is almost always the same: a cheap automated car wash or a quick hand wash spot.
So I decided to run an experiment. I spent two months visiting ten of the most popular car washes in Miami and Fort Lauderdale, from the big chains to the local hand wash spots. I brought my paint depth gauge, my inspection light, and my camera. What I found shocked me, and it's probably happening to your car right now.
The Experiment: 10 Car Washes, 1 Mission
I visited ten different car washes across Miami-Dade and Broward County. Some were automated tunnel washes, some were hand wash locations, and a few were "express detailing" spots that promised a full wash, wax, and interior clean in under 30 minutes.
I used the same vehicle for each test: a black 2019 Honda Accord. Black paint shows imperfections more clearly than any other color, making it the perfect test subject. Before each wash, I documented the condition of the paint. After each wash, I inspected the vehicle under direct sunlight and with a high-powered LED inspection light to reveal any new scratches, swirl marks, or damage.
Here's what I discovered.
The Results: A Breakdown of What I Found
Automated Tunnel Washes (4 Locations Tested)
Automated car washes are everywhere in Miami. They're fast, they're cheap, and they're incredibly convenient. You drive in, you drive out, and your car looks cleaner. But here's the problem: every single automated wash I tested caused visible damage to the paint.
The brushes used in these tunnels are rarely cleaned properly. They accumulate dirt, sand, and debris from hundreds of cars every day. When those brushes make contact with your paint, they're essentially dragging that contamination across your clear coat at high speed. The result is a spiderweb of fine scratches called swirl marks.
After just one wash at an automated location in Aventura, I counted over 50 new swirl marks on the hood alone. Under my inspection light, the paint looked like it had been buffed with sandpaper. The worst part? Most car owners don't notice this damage until it's too late. Swirl marks accumulate over time, and by the time your paint looks dull and hazy, the damage is already severe.
One location in Brickell advertised a "touchless" wash that used high-pressure water and strong chemicals instead of brushes. While this method didn't cause scratches, the chemicals were so harsh that they stripped away any existing wax or sealant on the paint. After three washes at this location, the paint felt rough to the touch and had lost all of its protective coating.
Hand Wash Locations (4 Locations Tested)
Hand washes sound like a safer option, right? Someone is physically washing your car with a sponge or mitt, so there's no risk of aggressive brushes damaging the paint. Unfortunately, that's not how it works in practice.
At three of the four hand wash locations I visited, the workers used the same dirty buckets and towels for every car. I watched as they washed a muddy pickup truck, rinsed the mitt in a single bucket of soapy water, and then used that same mitt on my freshly rinsed Honda. The dirt and grit from the previous vehicle were now being rubbed directly into my paint.
This is called cross-contamination, and it's one of the most common causes of paint damage at hand wash locations. Even if the workers are using soft mitts and gentle soap, if those mitts aren't clean, they're doing more harm than good.
At one location in Coral Gables, I watched a worker dry my car with a towel that had been used on at least five other vehicles before mine. The towel was visibly dirty, and when I inspected the paint afterward, I found dozens of new scratches and swirl marks. The worst part? The workers had no idea they were causing damage. They were simply following the process they'd been trained to use, which prioritized speed over quality.
The fourth hand wash location I tested was slightly better. They used a two-bucket wash method, which helps reduce cross-contamination, and their towels appeared to be clean. However, they still used a harsh all-purpose cleaner on the wheels and tires, and some of that cleaner splashed onto the paint. Over time, this type of chemical exposure can dull the finish and weaken any protective coatings.
Express Detailing Spots (2 Locations Tested)
These locations promise a full wash, wax, and interior clean in under 30 minutes. It sounds too good to be true, and in my experience, it absolutely is.
At both locations, the "wax" they applied was a spray-on product that provided almost no protection. I tested the water beading on the paint immediately after the service, and the results were mediocre at best. After one week of exposure to Miami's sun and rain, the wax had completely disappeared.
The interior cleaning was equally disappointing. At one location in Miami Beach, the workers used a strong chemical cleaner on the dashboard and door panels. The cleaner left a greasy residue that attracted dust, and within two days, the interior looked worse than it did before the service.
The speed of these services is their biggest selling point, but it's also their biggest flaw. There's simply no way to properly wash, decontaminate, and protect a vehicle in 30 minutes. Corners are cut, products are rushed, and the results reflect that.
The Hidden Costs of Cheap Car Washes
Most people choose cheap car washes because they seem like a good deal. You pay ten or fifteen dollars, your car looks cleaner, and you move on with your day. But what you don't see is the long-term damage being done to your paint.
Swirl marks, scratches, and oxidation don't appear overnight. They accumulate slowly, wash after wash, until one day you notice that your car's paint looks dull and faded. At that point, the only way to restore the finish is through paint correction, which can cost hundreds or even thousands of dollars depending on the severity of the damage.
In other words, those cheap car washes aren't saving you money. They're costing you money in the long run.
What Makes a Car Wash Safe?
After conducting this experiment, I can confidently say that not all car washes are created equal. A safe car wash follows a specific process designed to minimize the risk of damage. Here's what that process looks like.
Pre-Rinse and Foam Application
Before any physical contact is made with the paint, the vehicle should be thoroughly rinsed to remove loose dirt and debris. A thick layer of foam is then applied to the surface. This foam acts as a lubricant, allowing dirt to slide off the paint without being rubbed in.
Two-Bucket Wash Method
One bucket contains soapy water, and the other contains clean rinse water. After each pass with the wash mitt, the mitt is rinsed in the clean water bucket to remove dirt and grit. This prevents cross-contamination and reduces the risk of scratching the paint.
Microfiber Towels and Proper Drying Technique
The vehicle should be dried using clean, soft microfiber towels. These towels are designed to absorb water without scratching the paint. Each towel should be used on only one vehicle and then washed before being used again.
pH-Balanced Soaps and Gentle Chemicals
Harsh chemicals can strip away wax and sealant, leaving the paint vulnerable to UV damage and oxidation. A safe car wash uses pH-balanced soaps that clean effectively without damaging protective coatings.
Regular Maintenance and Protection
A truly safe car wash doesn't just clean your vehicle. It also applies a protective layer of wax or sealant to shield the paint from the elements. In Miami's harsh climate, this protection is essential for maintaining the longevity and appearance of your paint.

The Bottom Line
I started this experiment because I wanted to understand why so many of my clients were coming to me with damaged paint. After visiting ten car washes and documenting the results, the answer is clear: most car washes prioritize speed and profit over quality and safety.
If you care about your vehicle, if you want to preserve its value, and if you want it to look its best for years to come, you need to be selective about where you take it. Cheap car washes might save you a few dollars in the short term, but they'll cost you much more in the long run.
