Here’s some great info that Jay found on Promethean Planet.
Do not use abrasive powders, soap, detergents or petroleum based cleanersor solvents on the Activboard surface.
Scratches cannot be repaired or removed and will make ink and stain
removal in that area difficult. Do not use metal brushes, scrapers or abrasive
cleaning cloths.
The surface of the Activboard is made to very high standards of durability. In normal use you can expect satisfactory results every time with proper
maintenance.
Due to the high quality of projection surface it is not recommended that dry wipe markers are used on a regular basis. If, however, the surface needs cleaning after the use of such markers, we recommend the following methods:
• For normal dry wipe markers use Sandford Expo Towelettes 81850.
Do not use a board rubber.
• For permanent markers use Sandford spray cleaner 81803.
You should be able to obtain these products from an office supplies company.
A polish with standard household spray polish will restore the smooth writing
surface after cleaning.
I’ve heard that using Expo dry erase spray works just fine too, just don’t put so much on the board that it runs down between the seals on the bottom of it. That could ruin electronics and that would be bad. Might work best to spray it on a paper towel and then wipe it on the board.
