Commercial Carpet Cleaning

Commercial carpet receives many times the traffic of typical residential carpet. That's why it's important to select (fiber, construction, pile design, color) and install commercial carpet that fits a building user's needs. However, once that carpet is properly selected and installed, its durability and lasting beauty is highly dependent on the ongoing maintenance and cleaning programs.

The first critical component in programmed maintenance and cleaning is routine vacuuming coupled with rapid response to spots and spills. Carpet serves as a "sink" or collection point for everything that is tracked in or settles out of the air. Qualities such as sound absorption, slip resistance and soil-trapping ability makes it the most desirable floor covering in many buildings. Ultimately, however, even the best maintained carpet must be thoroughly cleaned to empty the "sink."

This is where IICRC-certifed technicians come in. They have the equipment, training and experience not only to empty the "sink," but also to restore the color and beauty of commercial carpet, while improving overall indoor environmental quality in the building.

What steps should I take to maintain carpet in a high-traffic area on a daily basis, and to deal with spills and stains?
  • It's a good idea to keep sand, grit and grass clippings off walkways outside entries to prevent inward tracking of these abrasive soils.
  • Purchase a properly sized entry mat, the bigger the better.  There must be room for at least two steps to sufficiently wipe soil from feet before encountering the installed carpet. A carpet with a nylon face and vinyl back is best for moisture and oils absorption, combined with the resiliency necessary to collect a quantity of particle soil. The IICRC suggests a rental mat, since that guarantees frequent maintenance. Place entry mats on hard surfaces rather than on carpet where they can trap moisture or cause plasticizer migration.
  • Vacuum, vacuum, vacuum daily, especially after major events. The sooner you collect soils from the surface, the easier it is to remove them. For most carpet, you should use an upright vacuum with brush agitation, unless your canister vacuum is particularly well designed. The wider the head, the more efficient.
  • Typically, deep cleaning should be accomplished on at least a semi-annual basis, with no more than two entry and high-traffic area "rinse" cleanings between the deep cleaning. This is dependent on traffic and daily maintenance as well. At a minimum, some attention should be given to primary entry areas on a quarterly basis.
  • If spots are treated immediately, most will respond with plain warm water and very little mild detergent added.
  • Use high-efficiency double-lined poly-fiber collection bags. This reduces periodic maintenance such as dusting of furniture, heating, ventilation and air conditioning (HVAC) filter exchange.
  • Make sure the HVAC system is slightly positively pressurized as well, which means that air is going out when doors are opened, rather than being sucked in. Proper air exchange rates can be calibrated according to ASHRAE regulations for the building with a trained HVAC contractor.
  • Ensure proper air filtration through the HVAC System. High-efficiency pleated filters, rather than inexpensive fiberglass filters, are recommended.
What is the best method of carpet cleaning: dry foam method or steam extraction?

Various methods of cleaning have different functions, both in interim maintenance and restorative cleaning. To note, both Shaw Industries and Mohawk, who together manufacture more than two-thirds of the world's carpet, recommend hot water extraction cleaning.
