There are many drivers do not pay attention to the car wash wash car chassis, likes only the surface of the car to clean it. As everyone knows, the car's chassis is the worst conditions, most in need of protection and care of the place. Undercar Cleaner is for cleaning car chassis or undercarriage, use this attachment with pressure washer, make the undercarriage cleaning easy and fast.
These are attachments of Pressure Washers, please note that all these cleaners can not be used without pressure washers.
