The objective or goal of any good carpet cleaning method, is always, to remove as much soil or foreign material as possible, from the carpet fibers. This should be accomplished without causing any damage or harm to, the carpet, humans or pets, or the internal or external environment. Deep steam or hot water cleaning with a truck mounted extraction system, has been almost universally acclaimed as the best method to accomplish all of this. But there are four essential elements of this procedure that should always be considered.
1. Chemical Type & Concentration The wet cleaning process is in reality a reaction or interaction of some sort, between one or more chemicals. This is true even where water alone is used. The more heavily soiled the carpet is, the more concentrated the chemical reagent will have to be, in order to complete this reaction in a reasonable amount of time. That is one reason why even deionized water with zero conductivity, will never be sufficient to remove really tough stains.
Many kinds of chemical reagents have been developed in this modern era, that have specific applications for particular cleaning situations. A good carpet cleaner will know how to choose a suitable detergent for prevailing conditions.
2. Temperature This is probably the most important aspect of the cleaning procedure. Chemical reactions are usually accelerated by elevated temperatures, and vice versa. See what happens to water when it reaches the boiling temperature. Carpets will require less chemicals, and a shorter time to clean up, when the cleaning solution is hot enough. Some people fear that hot water will cause damage to the carpet. This is possible where the carpet cleaner is uneducated and uninformed, but even the most powerful truck-mounted heater equipment can be regulated to deliver a maximum of 150 degrees F at the carpet surface. That will be quite safe, even for wool textiles.
Another advantage of using a hot solution, is that the fabric will dry faster. Also, heat also helps to reduce the surface tension of the cleaning solution, thereby facilitating soil removal. It has been determined that cleaning efficiency doubles with every 18 degree rise in temperature.
3. Time Chemical reactions require time for adequate completion. Of course the time required will vary according to the situation, but for most carpet cleaning conditions, a reaction time of ten to fifteen minutes will be quite sufficient. One problem that may occur is a reversal of sequestration if the carpet dries before the emulsion is washed out. Again, a well-trained technician will be fully aware of this, and will make the necessary adjustments.
4. Agitation. The main purpose for agitation is to spread the chemical uniformly and completely over the carpet fibers. A secondary purpose is to dislodge and soil particles that may be adhering to the fabric. But agitation also helps to speed up the chemical reaction of the cleaning solution.
Agitation may be accomplished by using various device. On the carpet, this is usually done with a grooming rake, especially for high density, plush pile carpets. A bonnet machine with rotating brushes is also very effective. Agitation on fabrics during upholstery cleaning is usually done with a horse hair brush, a sponge or a terry cloth towel.
Careful attention to these four elements during any carpet cleaning process will ensure that the cleaning procedure will be most effective.
