subject: How To Hire A Carpet Cleaning Company [print this page] The first thing to consider is the methods they will be using. Most experts agree that a truck or van powered extraction unit is the best tool for thorough extraction and soil removal. But equally important is the experience and training of the technician performing the cleaning. The technician should be IICRC certified in carpet cleaning and the company should be an IICRC certified firm. This is imperitive if your carpet has a warranty through Shaw or Mohawk. They require firms and technician to be certified for their warranty. Also check your local Better Business Bureau, angies list and ask for references. Next lets discuss the process. One of the first things they should do once on site is to identify the carpet fibers. They will most likely be nylon, polyester or polypropelene (olefin). These are durable fibers that clean up very nicely in most cases with the proper system of chemistry and equipment. The carpet could also be wool. Although wool makes up only a small percent of carpet out there it is very expensive and requires very special care. I have seen untrained carpet cleaners burn holes in wool using the same chemistry that would work great on nylon. The carpet should then be thoroughly vacuumed before any moisture is applied (this is crucial). If this is not done the preconditioner will emulsify or dissolve the otherwise easily removable soils. Once the vacuuming is performed the next step is to apply the preconditioner to the entire carpet (not just traffic lanes) and let it sit for usually at least 15 minutes. The preconditioner is one of the most important steps taken. I would compare it to the soap in a load of laundry, it breaks down all of the grease and grime. This is an area where technicians cannot cut corners the product should be certified by the Carpet & Rug Institute for the carpet fiber to be cleaned. The next step is to begin extraction using a high powered hot water (200+ degrees) extraction system. This literally flushes the carpet pile and removes the dirt and grime to the waste tank which sits in the van. The carpet should be rinsed with an acid rinse solution at around 5-6ph. This is usually mixed with the heated water in the van. This step is also critical to completely remove detergent residues and to leave the carpet fibers "slightly" acidic. Carpet will stay clean longer and resist wear if left at this ph after cleaning. Furniture should be moved, carpet should be cleaned underneath and furniture should be reset with foam blocks or plastic tabs to protect the carpet and furniture after cleaning. The technician must make dry passes to expedite the drying of the carpet. If carpet is not dried properly many issues can arise such as rapid resoiling, delamination, bacteria development, mold and odors. Carpet should be dry normally in 2-6 hours and never longer than 12-24 hours. The dry time will depend on the level of soiling (more requires more moisture), outside conditions, equipment used, and technician care. In Maine where we are based weather has a major influence on dry times. High speed air movers can greatly expidite drying. In summary carpet cleaners are a dime a dozen. A good reputable carpet cleaner that stands behind their work takes some research so do your homework. There are many good ones out there and when you find one keep them!
