Although hand washing is the preferred cleaning method, pressure washing may be used under these conditions.
- Ensure the water pressure is kept below 2000 psi (14 MPa).
- Keep the water temperature below 80°C (180°F).
- Use a spray nozzle with a 40-degree wide-angle spray pattern.
- Keep the nozzle at least 1 foot (300 mm) away from and perpendicular (at 90 degrees) to the graphic.
Important Note! Holding the nozzle of a pressure washer at an angle to the graphic may lift the film’s edges.
