Steam Cleaning is the process of injecting Hot water and Steam into the carpets fibers and the vacuuming up the hot water and moisture.
Steam Extraction cleaning is a diverse method and can be adapted to incorporate several different approaches.
Different approaches may include using cleaning solutions in the form of a liquid spray applied to the carpets first – this is a pre conditioner or pre-soak solution.
A pre conditioner is generally a blend of products which help to break down soils, dirt and stains in the carpets fibers. After applying the pre conditioner, a steam cleaning or Hot water extraction machine is used to flush out the cleaning solutions and remove the soils along with it. Using a pre conditioner, means the operator does not need to include cleaning shampoos or chemicals in the Steam/Hot water used to flush out the soils in the carpets.
This process leaves little or no chemicals in the carpets after the clean. There are no residual cleaning shampoos or chemicals left in the carpets to contribute to re soiling or the process which means carpets may get dirtier faster after cleaning.
The steam/Hot water may have a textile rinse added, this is an acetic solution which aids the removal of detergents such as shampoo and other DIY chemistry from the carpets, thoroughly rinsing out chemical and cleaning residues. The textile rinse fully evaporates after the carpets dry leaving the Carpets pile free of soils, chemicals and indoor air pollution.
The Steam Cleaning machines used for the Carpet cleaning process vary widely as do the tools used to extract the steam and soils from the carpets.
Vacuum machines may be a portable type. These machines are essential for High rise apartments, Commercial buildings or Buildings with closed door security policy. Portable vacuums are limited to the amount of vacuum which can be produced as well as heat to develop constant steam. Because they are electric they are limited to how much power can be run through a single 15amp power point.
However, portable Steam cleaning machines have come a long way in recent years with mainly American, Canadian, Italian and Australian manufacturers competing to develop machines that clean more efficiently and leave carpets drier.
Truck Mount machines usually petrol and sometimes diesel powered platforms produce heaps of steam and heat and excessive vacuum power.
Truck mounted carpet cleaning machines work very well for residential properties up to three levels high and for commercial premises with one or two levels high. They however do require access to the building with a vehicle and do not suit buildings with limited access, no available parking spot or where buildings have security concerns and the building entry point must remain closed and secured.
