What is the problem with washing the car with hard water?
Hard water causes two main problems: debris and spots. If the water is hard, the nozzles of the device will quickly clog, and the vehicle will leave a residue. The main goal of a car wash company is to paint the customer's car clean. Therefore, removing hardness from the water used in this cleaning process is an important part of customer satisfaction.
Commercial water softening system is the recommended solution due to its ability to balance the two culprits of hardness (calcium and magnesium) by adding sodium. This process enables the water to leave a spotless surface behind. This system is engineered to produce 35,000 GPD or 24 GPM.
In general, there are three types of water used for washing cars: Hard water, soft water, and Reverse osmosis (RO water).
Those who are dissatisfied with water stains may be careful to wash their cars with hard water after seeing the mess of appliances. However, hardness represents only part of the mineral content of water: calcium and magnesium ions. The total mineral content, called TDS or "total dissolved solids" in water treatment, is a true indicator of the spotting potential of water. The higher the TDS, the more spotting will occur.
1-Car wash with hard water
Car scale:The hardness of water is related to the content of calcium and magnesium. Hard water creates cleaning and rinsing problems when used with detergents and pre-soaks by consuming or reacting with some components in detergents. As a result, the amount of soap used might need to be increased to clean a car properly. In addition, there are chemical components in detergents that can react with untreated water hardness minerals to cause other problems.
2-Car wash with soft water
So, is soft water cleaner than hard water?
The answer depends on the situation.
Water softeners cannot remove dirt-causing minerals from water. Rather, the water softener exchanges sodium for hardness minerals, calcium, and magnesium ions. Soft water TDS is basically the same as hard water TDS. Soft water is low in calcium and high in sodium. Softening is beneficial for car washes, as minerals in softened water are more easily removed and do not form hardness-related deposits, but water with a high TDS, whether softened or not, creates stains. In contrast to the hardness ions, these sodium ions do not adversely affect detergents or dipping agents. Soft water is ideal for laundry detergents and dipping agents as it can be rinsed clean while reducing the amount of soap used.
It is advisable to wash your car with soft water.
