Valet Pro Snow Foam Combo 2 pre wash cleaner for car does the hard work for you, making car cleaning and maintenance pleasant. This high foaming solution enables the cleaner to penetrate the grime, with an extended contact time, thanks to its thickness and clinginess, for an efficient pre wash. As an alkaline solution, our pre wash foaming cleaner is very good at emulsifying oil, petrol and diesel stains, and at removing wax layers, dirt and grime, on every surface, being aluminium safe. Suitable for a thorough cleaning before polishing or surface-sealing. As every other Valet Pro product, it is rigorously tested before being released to insure security and to match the highest car care standards. Instructions: dilute it 1:3 when used with a foam lance and 1:10 with a pump spray. If using a lance, foam the entire vehicle, leave it to dwell, but not dry out. If using a pump spray, spray lower panels and do not allow to dry. Then, for lance and pump, rinse off with a pressure washer starting from the bottom.
