Look at a large whiteboard bought ten years ago and it rarely looks the way it did on day one, staining, ghosting, a surface that has visibly aged faster than the room around it. What separates a board that still looks new from one that does not usually comes down to surface quality and how it was cared for, not just how long it has been in use. Knowing that difference is what actually improves the next purchase, not just the next cleaning routine.
