During this time of year, understanding how to care for your car is more important than ever. Stonebridge Car Wash uses the best solvent on the planet, water, to optimize protecting your car from dirt and grime. Stonebridge Car Wash considers water hardness in determining which chemicals are right for your car. Hard water is created by the presence of Calcium and Magnesium and, to a lesser extent, Iron. These minerals are dissolved in the water. Stonebridge Car Wash uses chemicals that work best with the level of water hardness found in Aurora to create an optimal clean for your car.
