Which is the best cleaning method, Steam or Dry cleaning?
There are several methods but two of the basic methods are the wet (Steam cleaning) & dry methods. The term dry cleaning is a little bit misleading since all methods use some amount of water.
There is absolutely no similarity to the dry cleaning method that is used to clean clothing.
1. Dry Cleaning
One of the more popular so called dry cleaning methods is referred to as dry-chem or encapsulation. This process goes something like this: There is a cleaning product that is sprayed on the carpet and is then wiped up with an absorbent pad or cotton bonnet using a rotary type floor machine. (This is like a person soaping up, and then just wiping off with a towel, no rinsing with water! They get some dirt out, but will be left with a soapy residue.) This method is actually a surface or maintenance cleaning method. The down side is that it leaves a residue. The benefit is that it does dry in 1-3 hours.
2. Steam Cleaning
The most popular cleaning method is known as Steam Cleaning or Hot water extraction. There are basically two types:
A) The portable machine that plugs into your household current (like the one you would rent at the supermarket). The portable steam cleaning methods is not very good, because it is very limited in its power, and can leave the carpet very wet. Taking several days for the carpet to dry.
B) A much more preferred method is the powerful truck mounted hot water extraction unit (Truck Mount Steam Cleaning), which we use. The process works like this: Here again a cleaner is applied to the carpet, but it is then rinsed out with very hot water (you see once the water is heated up to 120 degrees, every 15-17 degree rise doubles the waters power to clean. Making the water itself a very aggressive cleaner). This method we use is the method recommended by Shaw Carpets Ind., the largest carpet manufacture in the world. DuPont as well as other large carpet manufactures also recommend Truck Mount Steam Cleaning, In fact they require it, to honour their warranty.
