You may have seen those black strips on carpet against walls or under doors. Better known as “filtration soiling,” these lines occur when air passes through the carpet as it attempts to get through the crack between the carpet and the baseboard or under a door. As the air passes through the edge of the carpet fiber, the sediments are deposited there. This process is gradual and only noticeable over a significant period of time and after the buildup has already occurred.
Can it be removed?
The appropriate word for the process is “difficult.” The reason the treatment is this way is because the soil is so fine that it penetrates deep into the carpet fibers and sometimes even into the carpet backing. These lines along the edges and doors will not be removed with our deep cleaning process. With time, effort and special treatment with products, reasonable results can be made.
What can I do?
To prevent these lines, it is best to vacuum and wipe those edges on a regular basis. Changing your air filter monthly will reduce the appearance and buildup of these lines. If you already have filtration soiling built up around your house, call Preferred Carpet Care to remove these lines.
