One of the often used carpet cleaning methods is the carpet shampoo method. The theory behind this method is generating sufficient amount of foam in the carpet, letting them to dry, have the resulting residue attract the dirt, dust and soil as well as other pollutants and then vacuum up the residue with the soil after few hours or the following day.
Therefore, this method will heavily rely on the shampoo products for carpet. The shampoo must have the following characteristics that will be the directive of their ingredients:
- Very high levels of foam that will minimize wetting
- Foam that is very stable
- High level of lubricity to minimize damage to the fiber of the carpet from the brushes
- Dry to a residue that is non-sticky
And so, a carpet shampoo must encompass high capacity of foaming chemical. The chemical substance used for foaming usually is the sodium lauryl sulfate. Others use its derivatives.This is the same chemical that you will find as active ingredient in most hair shampoo. This chemical, Sodium Lauryl Sulfate, as well as its derivatives can provide highly stable foam while being fair detergent agent. The con is that this substance dries to a sticky and soft residue that can cause re-soiling. Hence, due to the problem of re-soiling, carpet shampoos are usually formulated with anti-re-soiling additive like the addition of resins that are capable to minimize the tendency to re-soil.
Chemically speaking, shampoos are poor detergent agents and they simply bury the dust and dirt. In this case, shampoo cleaners are also formulated with optical brighteners that take the unseen ultraviolet/UV light and then convert it to visible light particles. This is the reason why the carpet appears brighter and cleaner than it actually is for some time. The downside, the yellow cast appearance of the carpet will appear and this yellowish appearance cannot be removed easily.
There are two main types of cleaning machines utilized in this cleaning method that most carpet cleaning San Gabriel utilize and these are the cylindrical foam and rotary shampoo. The first one, cylindrical foam machine makes use of air compressor to produce dry foam before the application of the foam to the carpet. The carpet is agitated next using revolving cylindrical brush that acts to comb foam through the carpet pile. The process leaves the dirt and other pollutants trapped in the carpet pile. In this method, proper and powerful vacuuming is very important before and after cleaning. The second machine, rotary shampoo, makes use of the rotary floor machine that sprays shampoo onto the carpet coming from the dispensing tank and then the rotary brush scatters the detergent to form the foam. Most carpet fibers and mills manufacturers discourage the use of this machine on their carpet because of the possible damage that might happen. Jute straining, bad odor and shrinkage is possible to happen to the carpet if the method is wrongly applied that can result to over-wetting (which is pretty common).
