HDPE fabrics require very little maintenance, but should be kept clean to ensure they look bright and attractive throughout their service life. To clean our fabrics, use a power washer or water hose with a light (diluted) detergent. Spray the fabric from the underside, starting at the top or peak, and then working down each side of the structure so the dust and debris will be washed off. If using a power washer, take care not to get the spray head too close to the fabric.
