Carpet should be deep cleaned periodically, in addition to vacuuming regularly. Particles like bacteria, dirt and dander will cling to carpet fibers and cannot be removed by vacuuming alone. A professional deep cleaning not only removes these particles, but it will also preserve your carpet and prevent it from wearing out prematurely. Under normal circumstances, a deep clean should only be needed once or twice a year. However, some situations may call for immediate professional cleaning. You might have pet odors or stains that need to be removed. If you have experienced flooding in your home, flood water extraction will need to be performed as soon as possible. Some stains may be so severe that they call for carpet replacement.
The two primary methods used in carpet cleaning are dry cleaning and hot water extraction. Out of the two, hot water extraction is used the most because it leaves less residue therefore re-soling is less likely to occur. Hot water extraction can also be done on all types of carpet. Dry cleaning is more expensive but takes less time to dry. However, it does leave behind more residue than hot water extraction, meaning carpet will need to be cleaned more frequently.
While it is important that you vacuum and spot clean regularly, how often a deep cleaning is needed will depend on whether you have kids or pets, and how busy your house is. There are steam cleaners available to rent, however it is best to leave deep carpet cleaning to the trained professionals.
