Those ugly black lines around the baseboards and doorways

How to Take Care of Carpet Filtration Lines

how to get rid of carpet filtration linesHave you noticed the black lines that sometimes appear in carpet along baseboards or doorways? These lines are called filtration lines because the soiling is caused by air passing through the carpet as it trying to filter through the crack between the carpet and the baseboard or the closed door. This buildup occurs over a significant amount of time and isn’t typically noticed until a large buildup accumulates.

This type of soiling is difficult to remove because the soil particles are so fine. They penetrate deep into the carpet fibers, sometimes even into the backing of the carpet. Is it possible to remove them? Sometimes. With special products, time and effort, reasonable results can be achieved, especially when you call the experts at North American Chem-Dry.

To help prevent filtration soiling, vacuum and wipe the edges of the carpeting regularly. The edges can be difficult to reach, so use an attachment to get all the way to the edge of the carpet. Staying on top of this will help keep filtration lines at bay.
