 A small whiteboard with pen and eraser clipped to top A whiteboard (also called a dry-erase or dry-wipe board) is the name for any glossy surface, most commonly coloured white, where markings can be made. Whiteboards operate analogously to chalkboards in that they allow markings to temporarily adhere to the surface of the board. These markings are removed more easily than if one were to use a chalkboard. The popularity of whiteboards increased rapidly in the mid-1990s and have become a fixture in many offices, meeting rooms, school classrooms, and other work environments.[1] I took this photograph of a whiteboard myself on an Olympus C-60 Zoom digital camera, and I reduced the size in Microsoft Photo Editor This image has been released into the public domain by its creator and original copyright holder. ...

Instead of using chalk (as on chalkboards) to make the markings, a special whiteboard erase marker containing removable ink is used (see non-permanent marker). Whiteboards are normally constructed using porcelain enameled steel. Steel whiteboards are magnetic, so one can use magnets to affix notes or a magnetic eraser to them. Porcelain boards are more durable than painted steel and standard melamin boards. Melamine resin and painted steel will fade to a slight gray color over time, as ink of the dry markers enters into the pores of the material. Porcelain, or vitreous enamel, is practically impermeable for dry marker ink and will remain white throughout the lifespan of the whiteboard. Both porcelain and melamine exhibit ghosting. Ghosting occurs as a result of the solvents (usually alcohol) in dry markers that effectively make the board cleaner where there has been writing. This remains visible after the ink is wiped off, but ghosting disappears after a short time. The term whiteboard is also used metaphorically to refer to features of computer software applications that simulate whiteboards. Virtual whiteboards allow one or more people to write or draw images on a simulated canvas. This is a common feature of many virtual meeting, collaboration, and instant messaging applications.

Advantages
Whiteboard ink markings are less susceptible to external factors, such as water or accidental erasure, because the ink adheres slightly better than chalk does to chalkboards. Using markers does not generate the dust that comes from using and erasing chalk, allowing their use in areas containing dust-sensitive equipment. Anybody that is allergic to chalk or is asthmatic can use whiteboards as an alternative. This article needs cleanup. ...

A whiteboard can be used as the background for a presentation from an overhead projector. This allows the person giving the presentation to fill in blanks or make comments by writing on the whiteboard. For instance, a form can be copied onto a transparency and projected, and the presenter can demonstrate how to fill it in on the whiteboard. Even so, projecting onto a whiteboard produces much more glare than onto a projection screen, making it difficult to read. An overhead projector is a display system that is used to display images to an audience. ...

Disadvantages Whiteboards are slightly more expensive than blackboards. In addition, only special whiteboard markers are suitable for use on whiteboards. Using other markers that resemble whiteboard markers but contain the wrong kind of ink creates markings that are hard or impossible to remove. However, some techniques have been developed, which include filling over them using a marker with the right type of removable ink and then erasing the ink; wiping the marks with acetone or alcohol; or by using board cleaning sprays or prepackaged wipes commercially available from the whiteboard manufacturers. In chemistry, acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and β-ketopropane) is the simplest representative of the ketones. ...

The white background can cause contrast problems for people with vision impairment.
Some people are sensitive or allergic to the strong odour of most whiteboard markers. Reduced-odour markers are available.
Whiteboard markers may create a more persistent mess than chalk, as the ink is difficult to remove from anything other than the surface of the board; dry-erase ink causes stains in clothing.
