(Those ugly black lines around the baseboards and underneath the doorways of your home.)
If you have light colored carpeting, don’t be surprised if you notice dark lines appearing 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. Filtration soiling usually takes a significant period of time to develop and is not normally noticed until a larger build-up has occurred.
Filtration soiling is difficult to remove because of the tiny soil particles that penetrate deep into the carpet pile, and can become trapped in 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.

To help prevent filtration soiling from happening on your carpet, remember to vacuum and wipe the edges of the carpeting on a regular basis.
