Let's fix 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 linesMany people start experiencing dark lines in their carpet next to or near baseboards, furniture, and doors. This is called filtration soiling. It happens when air attempts to pass through carpet while 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. Depending on the severity, it can’t always be removed. 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.
