Keeping the writing surface clean
Important
Before you clean your interactive whiteboard, turn off or disconnect your computer so that you don’t scramble the desktop icons or inadvertently activate applications when you wipe the screen.
To view dirt or streaks more easily, set your projector to standby (lamp off) mode.
With proper care, your SMART Board interactive whiteboard will provide years of trouble-free service. Follow these tips to keep the screen surface clean:
Don’t use dry-erase markers, which can be very difficult to remove.
If dry-erase ink is used, erase it as soon as possible after use. The longer dry-erase ink stays on your interactive whiteboard’s surface, the more difficult it is to remove.
If erasing doesn't completely remove dry-erase ink marks, clean the writing surface with a household glass cleaner, such as Windex, daily, weekly or as required.
Remove excess dry-erase dust with a damp cloth before using a cleaner.
Use dry-erase marker cleaner, such as Expo dry-erase cleaner, if you can still see marks after using a household glass cleaner.
Don’t spray cleaner directly onto the screen’s surface. Instead, spray a light amount of cleaner on a cloth and then gently wipe the screen.
Don’t allow excess glass or whiteboard cleaner to flow into the crack between the lower frame and the writing surface, or into the pen tray slots.
Use isopropyl alcohol for stubborn stains and ghosting.
Tip
For information on disinfecting your interactive whiteboard, see Disinfecting Your SMART Board Interactive Whiteboard.

You can use a high-odor dry-erase marker to remove marks from a permanent marker, because dry-erase ink contains solvents that can remove permanent ink. Cover the permanent ink with the dry-erase ink, and then wipe with a soft cloth while the ink is still wet. If any trace of the ink remains, spray a cloth with a glass or whiteboard cleaner and wipe the area clean.
Tip
When removing permanent marker ink, don’t use low-odor or non-scented dry-erase markers, which don’t contain the appropriate solvents.
