WHAT ARE SPOT-FREE RINSE?
Water treated with reverse osmosis and ion exchange systems for vehicle washes exhibits special properties - unlike normal municipal water, it doesn't leave scale deposits on vehicles when it dries. We can provide your washing facility with the materials necessary to turn it into a spot-free wash, dramatically improving your ability to clean.
ROTEK has been supplying RO systems for such spot-free rinse applications for the past 2 decades. Our RA series Reverse Osmosis System is the most economical match for this specific application. Moreover, we are also open to custom-made systems for special applications such as fighter jet rinse and high-speed train rinse.
WHY DO WE NEED RO WATER FOR SPOT-FREE RINSE?
A spot-free rise differs from a standard rinse in the sense that spot-free systems use water that has been softened and/or filtered through reverse osmosis, distillation, or deionization. These processes remove contaminants and particles that can harm your vehicle, otherwise known as Total Dissolved Solids or TDS.
TDS can include a number of minerals and metals, such as calcium, aluminum, sodium, magnesium, nitrates, phosphates, and others. If TDS are present in the rise used during a car wash, they tend to leave behind unsightly and hard-to-remove spots after they evaporate.
Spot-free rinses prevent spots on any vehicle, but if you already have spots, it’s important to remove them as quickly as possible.
Leaving TDS spots can lead the minerals and metals to bond to the vehicle’s exterior, causing damage to the automobile’s surface. At the very least, these minerals and metals can cause your car to appear lackluster. However, at worst, TDS can corrode the protective clear coat on your vehicle. Corrosion only gets worse over time. Eventually, the protective coat will be completely dissolved. Once that happens, your car’s actual paint finish will deteriorate.
