Those ugly black lines around the baseboards and under doorways.

How to Take Care of Carpet Filtration Lines

dark lines in carpet along the baseboard are filtration linesIf you have light colored carpet, you may have experienced dark lines that appear on the carpet near baseboards or doors. 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. 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 fibers, sometimes into the backing of the carpet. Can it be removed? Sometimes. With special products, time and effort, reasonable results can be achieved. To help prevent filtration soiling, vacuum and wipe the edges of the carpeting on a regular basis.
