Fleet graphics films can be easily cleaned using a pressure washer but can be damaged just as easily by improperly handling the water spray or incorrectly blending the cleaning solutions. Regular washing is highly recommended to avoid the necessity of deep cleaning and to prevent accumulating dirt. In order to keep the vinyl from degrading or lifting around the edges while pressure washing, it is important to adhere to the following guidelines:
- Nozzle pressure should never exceed 1,300 PSI.
- Water temperature should never exceed 140°F (60°C).
- Nozzle tip should never be closer than five feet from the graphics.
- Angle of water spray should be no shallower than 60° from perpendicular. Keep the nozzle spray pattern perpendicular to the overlapping direction.
- Detergent solutions should always be blended with water at the correct ratio and pH (between 6 and 8). A more concentrated solution can damage both the adhesive and vinyl.
- A post-washing, fresh-water rinse will help maintain the life of the paint and vinyl.
