The objective of carpet cleaning is removing soil. Cleaning can be accomplished by several methods , but regardless of the method chosen, These principles must be followed to achieve the best results.
Dry soil removal or vacuuming
Soil suspension-Soils that were not removed during the dry soil removal step are suspended to the fibers. This is accomplished through the fundamentals known as the cleaning pie or TACT and is the best way to get your carpet cleaned.
Time- Soil that has accumulated over months or years cannot be suspended in a matter of seconds. We pre-spray your carpet with a acid or akaline detergent depending on the type of soils. This pre-conditioner must dwell in the carpet for a period of time to be most effective . But it is very important not to let the pre-conditioner dry.
Agitiation -provides a uniform distribution of the pre-conditioner detergernt into the carpet fibers. This can be manually brushed or mechanicly and also helps lift the matted carpet fibers.
Chemicals-These detergents , builders or selected solvents must be used to suspend, emulsify or sapoify the various soils. Detergents used on stain resistant carpets must be anionic or nonionic with a ph not to exceed 10.
Tempature-Increasing tempature reduces the surface tension of the water , while it accelerates most chemical reactions ,thereby causing the carpet cleaning agents to fuction more efficiently
Finally soil extraction - Once the soil has been suspended they must be physically removed from the carpet . We do this with a powerful truck mounted machine at a tempature of 230 degrees and a high water pressure of 400 psi adding a carpet rinsing agent to remove all of the residue and lower th ph level back to it's original state.
