There are many different methods used when it comes to carpet cleaning. At times it can be hard to decide which method is best; it really comes down to which is best suited for the particular job in hand. In this article we will look at some of the dry cleaning methods.
The term dry cleaning is actually a misnomer – it should perhaps be called ‘low moisture carpet cleaning’. It is known as dry because the carpet can be brought back into use very soon after cleaning.
Absorbent Powder / Dry Extraction Cleaning
This method uses an absorbent substance such as sponges or powder which have been impregnated with water, solvent and detergent (small amounts). The soil is absorbed (once loosened) and held there until it is removed by vacuuming. This method enables the carpet to be used pretty much straight away; however, it is not great for heavily soiled carpets.
Bonnet Pad Cleaning
In this method a cleaning solution is sprayed over the surface of the carpet. The bonnets (absorbent pads) are then used to buff the carpet. These are attached to a mechanism and absorb the soil in the carpet. Big areas can be cleaned swiftly using this method. However, as with the absorbent powder / dry extraction method it is not particularly good for very dirty areas as the cleaning does not involve any rinsing action.
This is a traditional carpet cleaning method which makes use of a rotary floor machine. The machine is fitted with a solution tank and a shower feed brush. A shampoo solution is fed through the brush; at the same time the carpet is scrubbed. This is followed with a thorough vacuuming in order to remove any loose soil. This method provides a very good deep clean and is also fairly economical. Unfortunately, pile distortion can be a problem as a result of all the scrubbing.
Encapsulation is a fairly new method of carpet cleaning. It utilises a cleaning agent as well as a crystallising agent. The cleaning agent suspends the dirt which is then encapsulated by the crystallising agent, and in turn forms a crystal. This can then be vacuumed away. This method has the advantage that it does not leave behind much residue. However, it does not work well on carpets that have a lot of grease on them.
Before the cleaning is carried out a thorough inspection should take place in order to ascertain which method should be used. Regardless of the method, the carpet should be vacuumed thoroughly before any work is carried out. It is a recognised fact that a huge amount of dirt can be removed by vacuuming alone!
