Are the QWall easy to clean and keep clean? How long do they last? What products to use to clean to prevent staining, mold, mildew, scratches?

If installed and maintained properly, the QWALL products should last for many years. The product does carry a limited lifetime warranty. Guidelines for cleaning can be found in the back of the installation manual and are as follows, "To ensure long lasting life for your acrylic back walls: wipe them off after each use with a soft cloth. To clean the acrylic back walls use non-abrasive sprays or cream based cleaners. Avoid the use of aerosol spray cleaners. Never use abrasive cleansers, metal brushes or scrapers that could permanently scratch or dull the surface."
