Carpet Soil Filtration Lines

Soil filtration lines are distinct lines of discoloration caused by fine particle soils in the air and oily vapors being drawn through the nap of carpet and other fabrics. The source of these soils can be exhaust emissions from automobiles, coal or wood burning heaters, candles, fireplaces, cigarette smoke, volatilized cooking oils, decomposition of organic materials, carbon particles escaping through the filter of heating/cooling systems, and various light weight particulate matter.
