Car windshield washer fluids can be mixed, but it is not recommended. When mixing different types or brands of windshield washer fluids, due to variations in their chemical compositions, chemical reactions may occur, leading to the formation of sediment impurities. Over time, these impurities can accumulate in the rubber tubing, clogging the spray nozzles and affecting normal spraying. Long-term use of mixed fluids can also increase friction between the glass surface and the wiper blades, potentially causing scratches on the glass. Car windshield washer fluids are widely used for quick dirt removal and bright cleaning on various glass surfaces, including car windows, rearview mirrors, as well as household, office, door, window, and decorative glass, offering comprehensive performance.
