It is best to use a microfiber cloth and either soap & water or an isopropyl 50/50 mixture. Harsh chemicals may adversely affect the surface.
GF 111 is a 2.0 mil clear polypropylene film coated with a permanent acrylic pressure sensitive adhesive on a smooth paper liner. This laminate can turn any printed graphics into a writeable dry erase surface and is designed for use with dry erase markers. GF 111 is best suited for short-term or promotional indoor graphics, where long-term durability is not required.
For best results, we suggest the following dry erase brand marking pens: Avery Marks-a-lot® (chisel point), Expo Scents® (chisel point), Expo Bold color® (chisel Point), Expo regular® (chisel point) brand dry erase markers.
