30 Jan Have you noticed dark lines on your carpet around the perimeter of a room?
Have you noticed dark lines on your carpet, especially around the perimeter? These are more than likely soil filtration lines. Soil Filtration lines are dark soiled areas that develop gradually on your carpet. These can also be known as smog lines or perimeter soiling. The most common areas are around the edges of a room next to the wall, under floor length draperies and under doors. However, they can develop anywhere there is an air space such as between floorboards or spaces in the sub flooring. If you have rooms with doors that are closed at night, especially if windows are left open, are more likely to develop soil filtration lines.
The soiling is caused by the passage of air through or across the carpet. Air carries microscopic particle of dirt and soot. As air passes over the carpet, these soil particles settle and become embedded in the carpet pile yarns. In areas where the air flows over the carpet more than normal, the carpet acts as a filter, extracting the spoil particles from the air. The soil is very fine and will penetrate deeply into the yarns. Our technicians are trained to use special techniques to improve the appearance of soil filtration lines.
Unfortunately, this discoloration cannot always be removed completely. The degree of removal depends on the amount and type of soil, length of time the soil has accumulated, amount of air flow, color of carpet and type of fibers. However, in severe cases, especially on light colored carpets, traces may remain after cleaning. It is usually very difficult to remove filtration soiling completely from wool carpets.
Below is a great before and after picture of a soil filtration cleaning.
