filtration line

What are those black lines along the baseboards?

You may have seen dim, dirty-looking lines in the carpet along the baseboards, under doors, and on the stairs in your own house, or in the home of a neighbor or acquaintance. What exactly is it? Is it possible to remove it? Will it reappear?

The dark greyish or black discolorations that appear along the perimeter of rooms and in the doorways of certain homes can be embarrassing and frustrating at times. Not only do our clients trust us to clean their carpets, but they also trust us to advise them about how to care for them. We’ll talk about what these curious dark lines aren’t until we clarify what they are.

It has little to do with residual dust from sloppy housekeeping, contrary to popular belief. There isn’t a flaw in the carpet. No, contrary to popular belief, it is not mold. And pest control firms have been accused of wrongfully causing these unsightly lines with their treatments. So, what exactly is it? Filtration soiling is the term for it.

Filter soiling is most prevalent in homes with forced-air HVAC (heating, ventilation, and air conditioning) systems, though it can occur in any household. Air is pulled into the fabrics at some points in the carpet due to friction and temperature differentials. Pollutants in the air are trapped by the carpet fibers, which serve as a shield.

All of these emissions are carbon-based and are the product of combustion. Automobile emissions, factory air pollution, cigarette smoke, and even natural gas or oil furnaces are all common causes. This biomass, when mixed with oily residues from cooking and other causes, forms very strong electrostatic and chemical bonds with the carpet.

The particles themselves are microscopic and impossible to extract. Prevention is the safest course of action. Here are several suggestions for avoiding gray edges:

Check that all sources of combustion in your households, such as gas or oil heaters, cooking equipment, and water heaters, are working properly. Carbon levels are higher when incomplete combustion occurs as a result of malfunctioning equipment. This can lead to a lot of soiling.

An HVAC specialist should inspect heat exchangers, flues, and chimneys for leakage or unsafe operation. If you like burning candles, keep the strongly scented ones to a minimum. These candles’ oils do not entirely burn, leading to contaminants in the air and hastening filtration soiling.

Replace the air filters in your heating and cooling system with high-quality ones. This will necessitate machine changes. Consult a reputable contractor. Air purifiers should be used, particularly if there are smokers in the house. Tobacco smoke leaves one of the worst residues to get rid of.

Whether you’re going to use a fireplace or a wood stove, make sure there’s enough fresh air coming in to give the fireplace enough of an updraft. Otherwise, some of the smoke could enter the air and aid soil filtration. It’s possible that you’ll need to open a window with a crack. Ceiling fans should not be used in places where a fireplace is burning. Smoke can be drawn into the living room by air currents.

To clean soil filtration lines, Bluegrass Company & Hardwood Refinishing Company employs advanced cleaning agents and techniques. While we might not be able to completely remove the discoloration, we will normally change the look. Of course, the best line of protection is still prevention.

I’m a repeat customer with them and again they met my expectations! I think one reason is they’re attention to detail as well as not taking advantage of me as a senior citizen.. They advised me what they thought and I totally agreed instead of charging me for more than I needed. Highly recommend for homes in the Andover area. Will call them again!

Amazing work!! Their pricing was fair, their expertise on the matter was very obvious, and the efficiency of their work is unmatched! They were able to get me an appointment the day after calling, and seeing the carpet after their work was the difference between night and day. I moved out of an apartment with old 60’s carpeting, so I am being totally honest when I say I was astounded by how nice the end-product was. I also greatly appreciated the simplicity of the process and the consistent communication. If you need your carpeting cleaned, especially for move-out, these are your guys! I wiIl definitely work with them again if I ever need professional carpet cleaning in Lexington!! 👍
