Black Marks in Carpet Under Doorways

Quite often when we arrive on site for a professional carpet cleaning in Tyler, one of the first questions is whether black lines under doorways will come out. The answer is yes!

The grey or black lines you see under your doorways or furniture is what’s known as filtration marks. These marks are also found along the edges of walls. Your carpet acts like an air filter for the entire house. When air is pulled under a door, dust and debris is deposited as the air is forced through the small space causing a dark line.

Using a chemical designed for carbon removal, professional carpet cleaners are able to remove these lines. It is important that the chemicals used are flushed out with the hot water extraction method of carpet cleaning.

Filter lines can be kept to a minimum by vacuuming on a regular basis. It is also important to change your air conditioners filter more often if you see these lines appearing. If you so have some filter lines and want to remove them yourself you may try purchasing products specifically made for that purpose from carpet cleaning supply shops.

As with any other spots or spills that you may be uncomfortable removing, if you live in the Tyler TX area or anywhere else please call your local carpet cleaning professional.
