A manual car wash allows you to easily clean your car and almost any surface from most contaminants. But if you need to remove corrosion, old paint, or prepare the surface for primer application, then the sandblasting attachment will come to your aid, which will significantly expand the functionality of a conventional car wash. Suitable for Karcher car washes, the advantages of the device are the ability to quickly and accurately clean objects of any, even the most complex shape.
