How do I get permanent marker off a whiteboard?
No worries if those pesky permanent markers make their way into your whitespace. Just draw over it with an EXPO Dry Erase Marker and poof! It's gone.
What makes wet erase (like Vis-à-Vis) markers different from dry erase markers?
Wet erase markers contain water-soluble dyes and are intended for acetate, film or non-porous laminated surfaces. Wet erase markers can only be removed with a damp tissue or cloth. Dry erase markers erase with an eraser on most non-porous materials, like whiteboards, porcelain, melamine and glass.
Can I use dry erase and wet erase markers (like Vis-à-Vis) together?
Yes, if you have a quality board that withstands water, you can certainly use the two together. Restaurants commonly use this combination when designing their boards that display the house "Specials." Vis-à-Vis wet erase markers are used for the more permanent text on the boards, like the board heading and the days of the week; and EXPO Dry Erase markers are used for text that often changes, like the listing of daily specials. To remove Vis-à-Vis markers from your board, simply use a damp cloth on the markings.
How long is a marker supposed to last?
As with any writing instrument, this depends upon users and frequency of use. When not in use, EXPO markers stored horizontally with caps installed tightly will last approximately 2-3 years.
If my EXPO marker dries out, is there anything I can do to restore it or is it dead?
Yes, depending on the extent of solvent loss, the markers can often be restored. Place the cap back on the marker tightly and store tip down for 24 hours. The marker should revive. Once revived, store marker back to its normal horizontal position.
If EXPO markers are dry erase why aren't they washable?
Dry erase ink contains pigments and release agents. The release agents prevent the pigments from sticking to dry erase boards and non-porous surfaces. However, these small particles of color become trapped when they come in contact with clothing fibers and other porous objects and surfaces.
Is cleaning my whiteboard really necessary? How often should I clean it?
Yes! Cleaning your whiteboard is critical to its performance. Cleaning a whiteboard removes chemical build-up associated with repeated use of dry erase markers. We recommend once per week. Remember that it is very important to thoroughly erase a board BEFORE using EXPO Cleaners.
An EXPO Dry Erase marker was accidently used on our projection screen. How can this be removed?
Many EXPO users have had success removing ink from projection screens with a product called Re-Markable. This product is distributed by Quartet. Contact their customer service for retail outlets at (800) 541-0094 or visit their website at www.gbcoffice.com.
Can the markings be removed if an EXPO Dry Erase marker is accidentally used on a wet erase board?
Because wet erase boards have a laminated surface, which is usually more porous than dry erase board surfaces, dry erase ink may be difficult to remove from wet erase surfaces. Using harsh solvents may ruin your board. We suggest that you first contact the board/surface manufacturer.
