Soil found on a carpet can be classified as spots and stains; surface litter (paper, threads, lint, etc.); gritty unattached particles; and that which is adhering to the fibers. You can check out our others posts to see how to get rid of some specials stains and spots. But for the most part, your rug or carpet will always be getting soil trampled into it, and in high volume walk ways, such as hallways, and entrances, your carpet will start to show signs of distress very quickly if the carpet is not cared for properly.
Surface litter can be picked up with a vacuum. And a vacuum with an air purifier is also very helpful for those with allergies to dust mites and other common substances found on rugs and carpet. Although the surface litter is unsightly, generally this material does not soil or harm the carpet. Most of the gritty, unattached soil is tracked in on the feet, and is common in all households. But the longer the surface litter remains on the carpet, the more damage it will cause.
Gritty soil will scratch and produce pits on fibers to dull them, making them appear even more soiled than they may be. It also produces a cutting action, which removes fibers and shortens the life of the carpet. Remove this soil by daily vacuuming high traffic areas, and overall vacuuming at least once a week.
Soil, which gives the carpet its dirty look, is composed of sticky oils and greases containing tiny pieces of soil materials. By professional cleaning, this type of soil can be most thoroughly removed. The longer oily soil remains on the fiber, the more difficult it is to remove. Some oily type soils change chemically and produce a yellowish film on the fiber, which is impossible to remove. Other oils actually dissolve into some of the synthetic fibers, becoming part of the fibers themselves. These can not be removed without damage to the fibers.
For proper carpet maintenance, remove spots immediately, vacuum high traffic areas daily, vacuum thoroughly once a week, and have a professional cleaning done when main traffic areas in the house begin to show soil. In addition it is very important to make sure any spills or other stains get cleaned up quickly, set in stains are incredibly hard to remove, and can cost a lot of money to get them professionally cleaned.
