Will mildew grow on Sunbrella fabrics?
If Sunbrella fabrics are kept clean they will not mildew. One of the characteristic of acrylic fiber is that it will not support the growth of mildew, as a natural fiber such as cotton will. Mildew will and can grow on any surface that is dirty, so keeping your Sunbrella fabric clean will help you avoid any mildewing from growing. If mildew begins to become a problem with your cushions or umbrella please review our care and cleaning instructions.
