Why does sand damage carpet?
Hard grains of sand and dust sink between fibres and grind against them with every step. This friction slowly cuts the pile, dulls its sheen and makes walking paths look faded and flat before their time.
The damage does not show in a week. You see it after months, when the entrance path looks lighter than the rest of the room and the pile there feels shorter and rougher to the touch.
So removing grit before it works its way deep matters more than trying to restore appearance after the fibres have flattened. Vacuuming is the everyday tool for that.
