Some manufacturers claim that you don't need water or chemicals to clean their whiteboards. However you're probably already aware that when ink is left on a white board for long periods of time, there is faint shadow of the ink left on the board. When this happens, no amount of "dry" cleaning or erasing will remove all the ink. This is when you need to "wet" clean the board.

The first step to take before cleaning a whiteboard is to check to see if the client has the manufacturer's instructions for cleaning, and then follow those instructions. If they don't have the instructions but you know the manufacturer, contact them to get the proper cleaning instructions.

Encourage your clients to clean the boards at least once a week. If ink is left on longer than that it can leave permanent stains.

Cautions:

• Do not use dry erasers on wet ink. Make sure ink is completely dry first.
• Do not use chalkboard erasers on whiteboards. Only use erasers specifically designed for white boards.
• Do not use abrasives on white boards or you can damage the surface.
• Do not use Magic Erasers or they will scratch the surface.
• Do not use acetone or mineral spirits to clean whiteboards.

General cleaning instructions for whiteboards:

• Use a damp, non-abrasive cloth or sponge.
• Wash the board with a cleaner made especially for whiteboards, which you can buy at office supply stores. If this is not available, use a 50/50 water/alcohol mix.
• After cleaning, rinse the whiteboard with clean water. Use a squeegee to remove excess water and then wipe with a clean, dry, non-abrasive cloth.
