Why Is My Whiteboard So Dirty?

The video explains the phenomenon of ghosting on whiteboards caused by dry erase markers. It details the composition of dry erase and permanent markers, highlighting the role of solvents, pigments, and polymers. The key difference lies in the polymers, with dry erase markers using oily silicone polymers to form a barrier on non-porous surfaces. Over time, whiteboards can develop pores, leading to ghosting. The video also provides solutions for cleaning ghosting using solvents like rubbing alcohol.
