Before delving into carpet cleaning it is helpful to have a better understanding of the different methods that are employed. Generally speaking there are two broad categories of carpet cleaning: wet cleaning and dry cleaning. Each of these two can be further subdivided into basic methods which are: hot water extraction cleaning, bonnet cleaning, absorbent compound cleaning, and dry foam .
Hot water extraction is a method often referred to as “steam cleaning” although that is not completely accurate. This method involves very high temperature of water around 220 °F with high pressure application between 400 – 1200 PSI depending on the surface that is being treated. This is the method used by Green Zone, Our multi step procedure as outlined here results in the best clean. Hot water extraction is the cleaning method recommended by a majority of carpet manufacturers as outlined by the Carpet and Rug Institute and will help maintain the integrity of your carpet for the lifetimes of its use.
Dry Cleaning is a cleaning process that is most divergent from traditional in that a very small amount of water to extract the solvent. The term “dry” cleaning is a bit of a misnomer as this is mot accurately described as a low-moisture cleaning. The solvents utilized in this process are usually petroleum based making them similar in composition to other solvents such a paint thinner. This process results in fumes that can be quite hazardous to breathe. Professionals must be certified in order to offer this method. Dry Foam is a method that offers essentially an instant dry after cleaning. This process involves specialized crystallizing shampoo that is applied to the carpeting and dries. As it crystallizes it grabs onto the dirt and debris and these crystals can be picked up with a vacuum. There are some high end shampoo formulations that work effectively while there are others that can leave behind a sticky residue. Bonnet Cleaning involves the use of a machine with a rotary head with a removable absorbent bonnet or cleaning pad affixed to the bottom. The surface to be cleaned is treated with a cleaning solution and the rotating pad is moved across the surface to be cleaned. The further agitation from the spinning head allows the dirt and soil to be broken down for easy removal. One downside to these method is that if the absorbent pad is not frequently exchanged for a clean one the debris from one area can be redistributed to other and in other cases can cause it to be further embedded into the carpet.
