What's the best product to clean a whiteboard?

The best products for cleaning whiteboards depend on the situation. For daily maintenance: a dedicated dry-erase board cleaner spray (available at any office supply store) or plain water with a soft cloth. These remove fresh marker residue without residue of their own. For stubborn stains or ghosting: a whiteboard conditioning spray (which contains a mild cleaning agent and a conditioning oil that rejuvenates the surface) is more effective than plain cleaner. For deep cleaning or permanent marker removal: 70% isopropyl alcohol on a cloth removes most stubborn residue safely. Products to avoid: glass cleaner (leaves a silicone residue that interferes with future erasing), abrasive cleaners, or rough sponges that scratch the surface.
