How do I deep-clean a whiteboard that has heavy ghosting?

For heavy ghosting on melamine boards: apply isopropyl alcohol (70%+) with a soft cloth, let sit 30 seconds, then wipe in a circular motion. Repeat as needed. For porcelain boards: use a dedicated whiteboard cleaning spray or diluted hand sanitizer — porcelain's non-porous surface responds well to mild cleaning. For glass boards: glass cleaner works perfectly. Avoid abrasive pads on any whiteboard surface — they create micro-scratches that accelerate future ghosting. Very heavily ghosted melamine boards may need to be replaced rather than restored. Call OfficeFurniture2go.com at 1-800-460-0858.
