They're called filtration soil stains. Carpets are often subject to black soil lines at doorways, along the sides of stairs, and along the baseboards, and in my experience, most homeowners and businesses place the blame on the wrong causes.
What Causes Filtration Soil Lines?
Filtration marks are the result of oils and fine particulate molecules that bond to carpets, furniture, walls, and ceilings because of an electrical charge. The old adage, opposites attract is certainly true in this case.
The lines are created because as your furnace or heater runs, the air being loaded with added pollutants, rises and cools, then falling back down and depositing itself on cooler surfaces. This is because warm air is attracted to cooler surfaces.
The air seeks out cooler surfaces like outside walls, other rooms, or passage to cooler places like in the walls or under floors. A building breathes through these cracks and crevices, and as it passes from one place to another, carpeting acts as a trap for the pollutants.
Most homeowners and business people have never really considered that the largest air filters in any building are the carpet, upholstery, and drapes. This is why the lines appear at doorways where the doors are always closed or along the baseboards. As the air passes through the fabric, the oily particles are trapped and the black soil filtration appears. This is very hard to remove. But we can significantly improve filtration lines at Carpet Cleaning in Boulder, CO 80302.
Why Is It So Hard To Remove?
The oily soils are so small, that they not only form an electrical bond, but they may also fit very nicely onto the very sites on the fiber designed to hold the color of the carpet, also known as "dye sites". It makes the filtration soil hard to remove with carpet cleaning solutions alone.
What's even worse than incorrectly placing the blame for those black lines though, is the manner in which home owners attempt to remove them. The end result is damaged carpets, furniture, woodwork, and baseboards.
The best way to remove the lines and black streaks from soil filtration is to call in a professional. The work is time consuming and labor intensive. You can expect to pay more for this service, especially if done well.
Even professionals may have limited success removing the lines completely, but if they are allowed to persist, the damage can become permanent, greatly reducing the value and longevity of your carpets. Don't wait any longer to address this problem. We can help at Carpet Cleaning in Boulder, CO 80302.
