Chalkboard Vinyl is not designed for coated/sealed/treated stainless steel, brass or bronze surfaces.
Chalkboard vinyl works with *standard chalk, soft chalk, and liquid chalk markers.
*Please note that standard chalks vary and some may mar or scratch the vinyl surface due to their hardness and density, as well as the amount of pressure applied.
We recommend you test a small section of the film first. Soft chalk and Liquid Chalk Markers are ideal for this type of surface and will clean up with water and a damp cloth. We do NOT recommend abrasive cleaners or strong chemicals as it will degrade the vinyl surface.
