Air Filtration Lines

Those ugly black lines around the baseboards and under doorways

If you have light colored carpet, you may have experienced these dark lines that appear on the carpet. This soiling is called filtration soiling because it comes from air passing through the carpet as it is attempting to get through the crack between the carpet and the baseboard or under a closed door. As the air passes through the edge of the carpet pile, the microscopic soiling is deposited there (hence the term filtration soiling). This occurs over a significant period of time and is not noticed until a buildup has occurred.

This type of soiling is difficult to remove because the soil particles are so fine that they penetrate deep into the carpet pile, sometimes into the backing of the carpet. Can it be removed? Sometimes. With special products, time and effort, reasonable results can sometimes be achieved. To help prevent filtration soiling, vacuum and wipe the edges of the carpet on a regular basis. Be careful around the tack strip on the edge of the carpeting, it could nick your fingers!
