(Those ugly black lines around the baseboards and under doorways)
If you have light colored carpet, you may have experienced these dark lines that appear on the carpet. 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 build-up has occurred.
This type of soiling is difficult to remove because the soil particles are so fine that they penetrate deep into the carpet pile, sometimes into the backing of the carpet. Can it be removed? Our professional technicians using Chem Dry Filtration Line Remover solution, with time and effort, can achieve reasonable results. Call Chem-Dry Merrimack Valley for a free phone consultation and estimate. To help prevent filtration soiling, vacuum and wipe the edges of the carpeting on a regular basis.
