Why You Shouldn’t Use a Gas Station Car Wash

When your car’s covered in pollen, mud, or just the dust of everyday driving, a car wash feels like the fastest way to get it looking fresh again. And when you’re already at the gas station filling up, that glowing sign offering a quick “add-on wash” seems almost too easy to pass up.

But here’s the catch: gas station car washes are designed for speed and volume, not for taking care of your vehicle. In fact, that “convenience” could be costing you more in the long run.

Here are five reasons to think twice before rolling through the gas station wash.

1. They’re Tough on Your Paint

Gas station washes often use older machines with stiff brushes that aren’t regularly cleaned or maintained. Over time, those brushes collect grit, sand, and dirt particles from hundreds of vehicles. Instead of removing dirt, they can drag it across your car’s surface, leaving behind fine scratches and swirl marks. You may not notice them right away, but under sunlight, that dull, hazy look in your paint is a dead giveaway.

2. One Size Fits All (But Doesn’t Fit Well)

Every car is different—SUVs, sedans, trucks, and vehicles with roof racks or accessories all need slightly different attention. Gas station car washes are designed to push as many vehicles through as possible, which means there’s no adjustment for your car’s unique shape or needs. The result? Missed spots, streaks, and sometimes even awkward contact with mirrors, antennas, or accessories.

3. Low-Quality Soap & Water

A big part of a good car wash isn’t just the equipment—it’s the water and soap. Many gas station washes use strong, low-grade detergents that strip away dirt but also remove protective wax or sealants. Combine that with recycled water that may not be filtered thoroughly, and you end up with a wash that leaves behind streaks, water spots, or residue. Over time, that can dull your paint’s shine instead of protecting it.

4. Missed Details = Missed Protection

Your car’s dirtiest and most vulnerable spots are the ones you can’t always see—like wheel wells, undercarriages, and rims. This is where salt, mud, and road grime build up, and left unchecked, that buildup leads to corrosion and rust. Gas station washes rarely target these areas effectively. A quick “rinse and go” may make the outside look decent, but it doesn’t provide the thorough clean that protects your car in the long term.

5. No Pet Wash!

Let’s be honest—cars aren’t the only ones that get dirty. Your four-legged passengers bring along fur, mud, slobber, and paw prints that gas station washes can’t do anything about. At Watermill, we make it easy to take care of both your ride and your pup. While your car gets a deep clean, you can give your dog a refreshing bath in our self-service pet wash. That’s something no gas station can offer.
