If you rarely wash or have adherent dirt on your vehicle, we recommend a Self-Service Bay to produce the cleanest ride! This is because it offers the “human” element. Your vehicle cleaning is hand crafted to your liking! You can spend more time on areas that are dirtier than others unlike any machine that cleans all portions of the vehicle equally. Our self-service bays offer all the high-end carwash chemicals available in the industry. Most of these chemicals are applied “touch-free” with our wands and then rinsed off with a high pressure wash rinse. That being said, we do offer a single hog’s hair brush in our bays, but recommend customers to always rinse the brush off with the high pressure rinse before using it to avoid the chance of a micro scratch from a dirty brush (from prior customer). A hog’s hair brush has expensive natural bristles that cannot harm or scratch a vehicle finish if used when it’s clean. The reason some express tunnel car washes can scratch the finish of a vehicle is because the “dirty” vehicle ahead of you runs through the tunnel and some of that dirt trapped in the brush or cloth is then rubbed off on to the next vehicle, causing micro scratches.
