Keeping school and business equipment sanitized means having the right material best suited for this process. Porcelain and vinyl are both non-porous and easy to disinfect, which is why they are commonly used to make dry erase boards and tack boards, respectively. Non-porous means air and liquid cannot pass through. Bacteria, virus, mold and other microorganisms will remain on the surface and be eliminated when the surface is properly cleaned with a sanitizer. Porous surfaces allow these germs to become lodged in spaces that a sanitizer may not be able to reach, leaving the potential for germs to multiply and spread. School Outfitters carries porcelain dry erase boards that are double-sided, mobile and magnetic. We also carry vinyl tack boards in a multiple of colors and sizes to fit any sized space.
