(Those ugly black lines around the baseboards and underneath the doorways of your home.)
If you have light colored carpeting in your home, you may have noticed those dark lines that appear along the edges of the carpet. This specific kind of soiling is called filtration soiling because it comes from the air that is passing through the carpet as it is attempting to get through the crack between the carpet and the baseboard or underneath a closed door. This typically occurs over a significant period of time and is usually not noticed until a larger build-up has occurred.
This type of soiling is fairly difficult to remove because the soil particles are so fine that they penetrate deep into the carpet pile, and sometimes into the backing of the carpet. The effects of filtration soiling can usually be removed while achieving adequate results with the use of specialty cleaning products, and a reasonable amount of time and effort.
