Are you curious about how a “spot-free rinse” is created? Total Dissolved Solids (TDS) refers to anything dissolved in water, including the minerals that create hardness. If a TDS is higher than 50 parts per million (PPM), it may cause water spotting or streaks from water runoff. Stonebridge Car Wash uses a filtration process called Reverse Osmosis, creating what the car wash industry refers to as ‘spot-free water’ or a spot free rinse.
