Grip 321 Non-Caustic Traffic Film Remover 20L is a safe and versatile formula with a much lower pH that most conventional TFR's on the market. Whilst still being highly effective at breaking down and removing heavy soiling and grease, this milder 10.5pH formulation will not damage more sensitive surfaces or harm skin if accidental contact is made. Safer to use on new car paintwork but equally suitable for commcerial vehicles common in the automotive industries. Grip 321 is most effective when used as a pre-spray at a dilution rate of 1:10 and then rinsed away with a hot pressure washing machine.
