Always spot test before use.
Surfex HD can be used diluted from 1 part in 100 for light cleaning up to 100% concentration for maximum grease and oil removal.
Light degreasing
For use as a pressure washer shampoo, ensure that your lance is discharging at a concentration of 4% onto the surface (click here to find out how you can test your pressure washer and calculate the correct concentration)
For even lighter cleaning, such as interior upholstery, dilute surfex HD at 1-2% in water.
For heavier soil, for example around the wheel arches or tyres, 5-10% dilusion will be suitable.
Heavy degreasing
Saturate cool, greasy surfaces leave 1 to 5 minutes.
Agitate heavy soil with stiff bristled brush.
Rinse surface with clean cold water.
