If you use whiteboard markers at work or school, then the ink may stain your clothes occasionally. It might not go with ordinary washing. However, you can use some special agents to get it off easily, like, a combination of vinegar and rubbing alcohol. You can also run murphy oil on the surface to get rid of the stain and then wash it with mild dishwashing soap. However, the agent may vary depending upon the type of cloth and marker ink. The above solution might not suit all the types. So, it depends a lot on upon type of marker you use.
