The Pros and Cons of Touchless Car Washes: What You Need to Know

Many people believe that automatic car washes, particularly those with large circular brushes, can damage a vehicle’s paint and clear coat, or even break components. Some argue that these washes are only worth considering for cheap rental cars. However, among automotive enthusiasts, touchless car washes are often seen as a more favorable option.

It’s important to note that touchless car washes have their advantages and disadvantages. Depending on your specific detailing needs, a touchless car wash may or may not be suitable for you.

Touchless car washes have been around for quite some time, and while their basic principles are not new, advancements in technology have improved their effectiveness. These systems do not use brushes that come into direct contact with the vehicle. Instead, they rely on high-pressure water jets and specialized cleaning chemicals to remove dirt and grime.

The process involves directing jets of water onto the vehicle’s surface, often preceded by the application of soap or other strong chemicals to loosen contaminants. However, while high-water pressure and potent cleaners are essential for removing stubborn dirt, excessive pressure or overly harsh chemicals can lead to issues.

Touchless car washes often struggle to thoroughly clean vehicles. The reliance on strong chemicals and high-pressure water may not adequately remove stubborn contaminants such as tar, bugs, or bird droppings. In many cases, vehicles exit the wash with dirt still clinging to hard-to-reach areas, and the chemicals used can be harmful to the environment.

For example, residues from love bugs or bird droppings left on the vehicle can cause significant damage over time if not properly cleaned. Ultimately, the best approach for maintaining your vehicle is to use trusted detailing and sealant products, applied by hand with a high-quality microfiber cloth. This method allows for greater control and better protection against potential damage.

While touchless car washes are generally safer than conventional automatic washes that utilize brushes, they still pose risks. The chemicals used can be abrasive and toxic, containing volatile organic compounds (VOCs) that may irritate skin or damage certain vehicle surfaces over time.

Additionally, if the water jets are not calibrated correctly, the high pressure can be problematic. Any remaining dirt or grime on the vehicle after a touchless wash can lead to damage, especially if it includes acidic substances like bird droppings.

Furthermore, touchless car washes may use recycled water that contains minerals, which can leave hard water spots on your paint and potentially etch the clear coat.
