When talking about traffic lanes, carpet cleaners are referring to the paths of wear and tear and build up of dirt or areas of the carpet walked on the most. These tend to be at entry ways to the home and in the middle of halls. Traffic lanes are one of the most difficult issues carpet cleaning professionals deal with.
The biggest problem with traffic paths comes from the damage caused by people’s shoes. Abrasion caused by shoes and sands on the carpet fibers cause a dulling effect on the carpet that cannot be cleaned out. Often this makes the carpet look dirty even though no dirt is present.
Since the carpet along the edge against the walls is not walked on once all the carpet is cleaned the traffic lanes stand out. When dirt is removed the damaged carpet is exposed and this can even make the traffic lanes appear worse than before cleaning.
