When using the foam nozzle of the car wash machine, ensure that the car wash fluid is sufficient and properly diluted to avoid nozzle blockage or damage. After use, the nozzle should be cleaned in a timely manner to remove residual car wash fluid and impurities, and to keep the nozzle unobstructed and clean. During storage and use, the nozzle should be protected from collision or compression to prevent deformation or damage.

The delicate foam produced by the foam nozzle can penetrate into the tiny gaps and depressions on the vehicle surface, effectively remove stains and impurities, and improve the cleaning efficiency. Compared with the traditional direct water spray cleaning, foam cleaning can reduce water consumption and waste of water resources, which conforms to the environmental protection concept of modern society. The detergent ingredients in the foam are fully diluted and dispersed, reducing the direct impact and wear on the paint, and helping to protect the gloss and integrity of the paint. Rich foam covers the vehicle surface, making the car washing process more intuitive and interesting, and improving the user's car washing experience.
