We recommend the use of a good PH neutral car shampoo to wash your car, we also recommend hand wash only.  Using a pressure washer is ok but try to keep the spray away from the edges as best as possible as this could lift the PPF if at a certain angle.  Also make sure you have the correct pressure washer nozzle that is designed for washing cars and not the removal of patio dirt.  The correct nozzle is a fan shape and not a point style dirt killer nozzle as these can damage the paintwork.  Using an automatic car wash or ‘waterless’ washing could result in your car taking damage to the PPF and its self healing layer.  We can advise on what products to use and how to use them.
