Carpet Filtration Soiling

Posted on February 18, 2018

Do you notice Dirty Dark Lines Around the Edges of your Carpet?

If you have light colored carpet, then you have came across these dark lines that show up on the edges of the carpet. This soiling known as Carpet Filtration Soiling because it appears from air passing through the carpet as it is working to get within the seams of the carpet, wall, baseboard or closed door. This occurs over a significant time period and isn't noticeable until a build-up has occurred.

Dark, grey or brown lines under doors, around walls, underneath draperies and along the edges of stairs are problems of an aggravating problem. This post explains the cause of the issue and suggests effective methods of prevention and correction. The removing of filtration soiling won't be successful with normal rug cleaning procedures. The removal of filtration soiling is another process which may take up to 40 minutes per room. Filtration soil removal this is definitely time intensive and oftentimes expensive exercise and you have to consider the price of filtration soil removal to carpet replacement.

What is Carpet Filtration Soiling?

Carpet Filtration soiling is the buildup of airborne soil—dust, smog, tobacco smoke and other pollutants—where airflow is concentrated and directed over or via a carpet’s pile. The rug “filters” out these pollutants and gradually becomes soiled and dark. The commonest area you notice filtration soil ranges from and shut to walls. Filtration soil is more evident on white or cream colored carpet.

In addition to the areas shown in the accompanying photographs, filtration soiling may appear anywhere air flows over or within the pile, including places where the carpet’s back is punctured or torn by installation tools, along seams that abut baseboards, around railings on stairs, together with other areas. You will even view it as around the holes produced in carpet’s backings by the pins of tackless strip. In these cases, the trail taken by the air differs, but the reason for the thing is the same.

Carpet Filtration Soiling may appear during a period of only weeks, or it may take months or even years to become visible. The severity no matter what the soiling might be proportional to the amount of airflow and of course the relative dirtiness no matter the air. Its color will possibly vary in accordance with the kind of contaminants present. Auto emissions are grey to black; tobacco smoke is tan to brown (and much better to remove by cleaning).

It very visible on carpet of lighter colors, such as off-whites, light grays, beiges and pastels.

Is the Carpet Considered Defective when Carpet Filtration Soiling Occurs?

No. Filtration soiling is not the results of any defect in your floor or its components, neither is it a sign of low quality. It'll show on any carpet regardless of price, style, color, construction or face fiber. Since it is caused by airborne pollutants being deposited on your floor after it's installed, filtration soil is just not full of anything done when carpeting or its pile fibers are manufactured. While fluorochemical soil retardants (e.g., Scotchgard, Teflon, etc.) could make it somewhat less troublesome remove, no fiber modification or protective finish can prevent filtration soiling from going on.

What Causes the Airflow?

Normally, the airflow is created by hvac air conditioning systems, thermal expansion and contraction of air, or natural convection currents within the structure. Additionally it may be brought on by wind blowing through windows that regularly remain open.

Can Carpet Filtration Soiling Be Prevented?

Leaving inside doors open whenever possible will assist in preventing filtration soil from accumulating in doorways. In other areas the airflow itself needs to be stopped. Along walls and staircases, the carpet will need to be disengaged and the gaps through which air flows needs to be completely sealed off. (Silicone caulking and polyurethane foam insulation are ideal for this purpose.) However, if any gaps remain, air will find them. Sealing off some gaps may simply force air to search out another route—possibly through the carpet in a different area.

Can It Be Corrected?

Usually filtration soil is no less than partially correctable by knowledgeable cleaner; however, it rarely responds completely to routine cleaning. Filtration soil consists primarily of extremely fine particles—slightly smaller than soil from different sources—which can be really tough to remove. It is assumed that because of their small size, the particles are held stubbornly besides the fiber's and are not easily removed in the conventional carpet cleaning service process. Some sections of filtration soil—auto emissions, for instance—are oily naturally and has an affinity for synthetic carpet fibers. These characteristics, mixed with the proven fact that the soil typically remains on the fibers for months or years, make filtration soil highly proof against ordinary cleaning. Natural fibers like wool cannot tolerate the chemically aggressive cleaning techniques usually required to remove filtration soil.

This sort of soiling is difficult to remove since the soil particles are so fine that these penetrate deep into the rug pile, sometimes into the backing no matter what the carpet. Can it be removed? Sometimes. With special products, effort and time, reasonable results could be achieved. Call The Carpet Cleaning Co. at 916-706-3211 for a free consultation and estimate. To assist with the prevention of carpet filtration soiling, vacuum and wipe the perimeters of the carpeting on a daily basis.
