Not only was this carpet excessively soiled, it was also very abraded. Abrasion occurs when dirt “sands down” carpet fibers in a high traffic area. Most of the time, it happens where a hard surface floor meets a carpet like a kitchen floor, a bathroom floor or any hardwoods meet up with a carpet.
How to avoid abrasion? The answer is to vacuum very often. Also clean the hard surface floors more often. This keeps the “sanding” of the fibers to a minimum. Also, it is recommended to have the high traffic areas cleaned at least once a year.
In this picture, I was able to remove the dirt, soils and spots. However, the abraded high traffic pattern remained. These areas are permanent but can be avoided.
