Periodic cleaning is recommended. A regular, seasonal cleaning program will dramatically help to prevent noticeable weathering and dirt build-up. To remove airborne debris and dust, a vacuum or soft brush can be used. To treat liquid stains, remove spills immediately with a clean, damp cotton cloth or with detergent soap and warm water. Carpet and fabric cleaners are usually compatible (it is advised to test on a small area prior to full application). Do not use strong solvents, highly alkaline, or abrasive cleaning agents. Do not completely saturate the material with cleaning solution or water. The slight shedding of fibers is normal and not indicative of any defect
