Cleaning your carpet by yourself can be a tall order and that is why commercial carpet cleaning is big business especially in cases where thorough or heavy-duty carpet cleaning. The following are some of the common cleaning methods:1. Wet cleaningThis is also known as steam cleaning or hot water extraction. Pre-conditioning of the carpet is done first, by the use of chemical reagents that liquefy soil and oil-based substances that may be in the carpet fibers. Water is heated to nearly boiling point then pressurized and injected into the carpet. The solution is then extracted by use of vacuum after roughly 10-15 minutes.Advantages of using this method include the fact that getting the soil from deep within the carpet is possible. High temperatures, chemical concentration, and pressure can be used for cleaning. There is added reaction time for the cleaning solvents to complete their purpose. Disadvantages of using this method are that it takes a long time for the carpet to dry and that the process requires expensive equipment for efficiency.2. Using an absorbent padThis is a cleaning method that is also referred to as bonnet cleaning. Is usually preferred for light maintenance. It could still be used for routine cleaning. It is a method of cleaning that is done by vacuuming the carpet, spraying a chemical solution on it through use of an electric sprayer or a hand pump. The solution is then left on the carpet for some time to allow reaction.The pad or bonnet that looks like a towel is usually placed on a drive block of a rotary floor machine and it is then spun over the carpet surface. This action is beneficial in impregnating carpet fibers with chemical solutions then removing it together with the dirt later on.The advantages of this method are that it is inexpensive, simple, and fast. It has also shown to have great results when dealing with lightly soiled carpets. The disadvantages of this process are that only the top 1/3 of the carpet is cleaned as the method is not able to reach any lower. This gives room for the accumulation of dirt and chemicals at the bottom of the carpet.3. Dry cleaning with an absorbent compoundA mixture of some solvents and cleaning agents are spread on the carpet then worked into the carpet with a machine that is fitted with counter-rotating brushes. The powder collects dirt from the carpet. It is usually left on the carpet for 10-15 minutes before it is vacuumed.The advantages to this method are that the process requires no professionals and only needs about 20 minutes to dry. The disadvantages are that the powder tends to build up with time and become excessive, because the cleaning method cannot provide for deep cleaning.4. Dry foam or rotary shampoo methodA cleaning agent helps suspend dirt on the carpet where the dirt is made into foam and worked in the carpet via rotating brushes. After some time, the foam is removed by use of a vacuum.The advantages are that it is inexpensive, simple to use, and is fast for both drying and reuse. The disadvantages are that cleaning does not reach below the surface nor are high temperatures for cleaning attained.
