Question: What are the main steps I can expect a certified professional to take when cleaning my carpet? [Note: Ad or content links featured on this page are not necessarily affiliated with IICRC (The cleantrust) and should not be considered a recommendation or endorsement by IICRC (The cleantrust)].
The principles of carpet cleaning are listed in the IICRC S100 Standard and Reference Guide for Professional Carpet Cleaning. These include:
- Dry Soil Removal - thorough vacuuming using an upright vacuum with brush agitation and a high-efficiency double-lined collection bag or final filter.
- Soil Suspension - There are four fundamentals in soil suspension: application of preconditioning Chemical cleaning agents to separate soil from fibers prior to extraction; using Heat or temperature to speed chemical reactions; Agitation for proper chemical distribution, and dwell Time (allowing the cleaning agents time to dissolve soil) so desired chemical reactions can optimize soil extraction. The acronym "CHAT" makes the fundamentals of soil suspension easier to remember.
- Soil Extraction - Any method of cleaning must physically remove soils if it is to be successful. Soil removal takes place with dry vacuuming, wet vacuuming, absorption, and rinsing. The most popular deep cleaning method for soil removal among professionals is hot water extraction.
- Grooming, as necessary - Grooming has little to do with physical soil removal; however, it is needed to eliminate pile distortion and matting, to properly distribute additives, such as carpet protectors, and to create a consistent appearance.
- Drying - Damp carpet resoils rapidly, creates potential for slip-fall problems and ultimately, can grow bacteria and mold with associated odor.
