The importance of removing carpet soil:
When I am estimating, or cleaning someone's, carpets they almost always ask the question, "Why are there dark traffic patterns in my carpets, and is there any thing I can do about it?" These dark traffic patterns are often the result of "carpet soil" scaring the carpet fibers. These scars permanently damage the carpet fiber and change the way carpet reflects light.
Carpet soil typically consists of dust, dander, hair, dead skin cells, dust mites, dust mite feces, oils, bacteria and various kinds of dirt. This lethal concoction can reak havoc on you, or a family member's, allergies not to mention the smell and the yucky feel of the carpets. If you have pet urine, feces, etc. the problem is even worse. This carpet soil acts like sand paper and literally grinds the carpet fibers until all of the color and texture is gone. Imagine having two brand new yellow pencils and each day you rub the pencils together for a few seconds but you never used or sharpened the pencils. What color would the yellow pencils be in 30,40, or even 60 days? If you guessed BLACK you are correct. The friction from rubbing the pencils together causes heat and the heat is what melts the color of the pencil. The same thing is happening on your carpets only on a much larger scale.
Is there anything you can do to prevent this? Yes! First of all you need to follow your manufactures recommendations concerning carpet care: 1). Vacuum your carpets at least three times per week. If you can use a HEPA filtration vacuum. This type of vacuum will pick up the smallest of particles and is excellent for people with allergies. 2). Wear socks or indoor slippers and never go barefoot. On the bottom of foot you have 250,000 sweat glands that release oil, dirt, and dead skin into your carpets. 3). Professionally STEAM CLEAN your carpets at least once per year. There are other methods available for cleaning carpets but Mohawk & Shaw (the two largest carpet manufactures in the United States) recommend ONLY STEAM CLEANING. ALL OTHER METHODS WILL VOID YOUR CARPET'S WARRANTY. 4). Make sure that the professional carpet cleaner is just that a PROFESSIONAL. A professional will have a truck mounted steam cleaning unit and they will be educated in the area of cleaning. 5). Ask and make sure the professional carpet cleaner is going to pre-vacuum your carpets before cleaning them. 80% of all dry particulates can be removed with a quality vacuum. How much better is the STEAM CLEANING going to work once this 80% is removed. IF THEY DO NOT MAKE IT A PRACTICE TO PREVACUUM THEN THEY ARE NOT A PROFESSIONAL. 6). Apply carpet protectant once the cleaning is finished. Carpet protectant prevents the fibers from scaring and being sanded down. A REAL PROFESSIONAL WILL ALWAYS APPLY CARPET PROTECTANT BECAUSE HE KNOWS IT IS THE RIGHT THING TO DO!
