The one thing all chalk markers do have in common, regardless of who manufactures the marker is the fact that they use pigment based ink. Fine ground powder suspended in liquid solution makes pigment ink. When dry this chalk liquid provides the characteristic look of chalk markers, resembling the look of chalk. Pigment is good for many reasons, the greatest, but unseen one is that pigment is resistant to UV light. For this reason they do not fade as fast as dye based markers. Dye based markers include the classic whiteboard marker and permanent Sharpie brand marker. Both work well for indoor applications they are intended for, they will fade quickly when exposed to the sun.
Even though they make a strong bold mark, waterproof chalk markers are semi-permanent removed with Windex. The marks made are resistant to UV light, so they will not fade. Both the Zig Posterman Waterproof and Markal Pro-Wash D (detergent) remove with high pH cleaners. Though our testing has found that the Markal products, as industrial level markers tend to take a bit more effort to remove.
