If the area being cleaned has furniture, you should remove as much as possible. 4. Thoroughly vacuum the carpet. If the pile is crushed or matted, use a pile brush to loosen the soils which will make vacuuming more effective. 5. Pre-spray a good amount of the pre-spray. 6. Using a grooming tool, agitate the pre spray deep into the fibers then let it sit for 10 - 15 minutes, making sure that it doesn't dry out. There are many different colored yarns being used and the entire process is capable of producing very intricate patterns from designs that are pre-determined. Normally, woven is the highest quality of carpet on the market. Tufted This type of carpet is produced on a tufting machine by using either a single colored or sometimes a non colored yarn. Antique carpets and rugs are imported mostly from China, Persia, India, Afghanistan, Caucasus, and Turkey. Some of the famous weaving areas of such antique carpets include Kashan, Agra, and many other locations. Antique carpets have a more artistic integrity, as they are exclusively hand woven. They are sold all over the world, with clients more than willing to pay whatever they have to in order to redefine their home and decorate in style. Hot water extraction The hot water extraction system is highly recommended, as it considered to be one of the best methods for carpet cleaning. Also known as steam cleaning, the process consists of spraying a mixture of water and detergent into the pile and recovering the water and soil with a powerful vacuum that puts it into a holding tank. Even with professional installation, you won't pay near as much as you would for hard surfaces. Unlike hard surfaces, carpet can keep you comfortable if you decide to lay down on it. Life span The carpets of today are very durable and can outlast most other types of flooring available on the market. All you have to do is select a type of carpet that has a life span of 5 - 30 years or more, which is very common now days. By the late 1960s, polyester was introduced into the carpet industry as a face yarn. In hand, feel, and appearance it is similar to nylon, although it doesn't possess that same resiliency. Polyester doesn't absorb water based spills, isn't affected by urine or kool-aid, but it will absorb oil based spills.
