When you use a Snow Foam Lance as part of your pre-wash process you reduce the risk of swirl marks and scratches. Snow foam works by loosening and lifting contaminants away from the surface.
There are a variety of different pressure washers on the market and they all need different adaptor types to fit to a snow foam lance.
This listing is for a Kew/Alto/Nilfisk
Please note: Adaptor only (Snow Foam Lance not included)
