This method involves hot water being fed to a spray-extraction tool or wand; this is coupled to a pump-vacuum power unit. The cleaning solution is injected under pressure into the carpet through water-jet nozzles. This water gets into the fibers all the way down to the primary backing. This process loosens embedded soils, removes oil and grease deposits, re-emulsifies detergent residue all of which are immediately extracted by extremely powerful vacuum systems.
There are many types of steam carpet cleaner on the market ranging from small portables up to the extremely powerful and effective truck-mounted units. The principle is similar whether using a portable or truck mounted unit, hot water or solution is injected into the carpet under pressure and is then extracted almost instantly, removing soils, residues as well as spots and some stains.
The truck mounted units are made so that only the hose and wand are taken into the building being cleaned. These incredibly powerful units, delivering hot water and generating a high vacuum recovery can be powered by diesel fuel, gas, propane or by the truck’s motor.
Majority of fibers producers, carpet manufacturers and professional cleaners endorse this process for achieving efficient soil removal. With the present state-of-the-art equipment we are proficient at high production with fewer residues as long as the proper chemicals are used and the operators are adequately trained.
Steam Carpet Cleaning: Methods
1. This first method involves a traffic lane cleaner being sprayed onto the traffic lanes and then agitated into the fibers. The whole area is then cleaned using a hot water extractor that has a cleaning solution being injected into the fibers through the wand. This method isn’t going to rinse the fiber. This way leaves more cleaning solutions residue behind.
2. The second method involves a free rinse along with emulsifying pre-spray being sprayed onto the entire carpet. This is then agitated into the fibers. The whole area is then extracted using a specially formulated rinsing agent that is injected into the fibers through the wand. This method works more effectively at achieving a cleaner fiber. The main factors behind this are the improved pre-sprays and the thorough rinsing of the fiber reduces the amount of residue cleaning solution left in the carpet.
Note: The residue cleaning solution can also cause hoses and jets in becoming clogged as well as damaging the water pumps if not flushed out with clear water following every use.
The cleaning is enhanced through the rinsing capacity to:
- Neutralize any alkalinity contained in the pre-spray
- Lock migrant dyes back into the fibers
- Ceases soils from redepositing back onto the fibers. This can be done by sequestering agents
Once a carpet fiber is rinsed using plain water, the calcium/magnesium particles (contained in the water) cause the detergent molecules to drop the soils they have emulsified. These detergent molecules then begin emulsifying the calcium/magnesium particles. The soils redeposit back into the carpet fiber which brings about resoiling.
Tip: When a rinsing agent (utilize the extraction rinse to prevent resoiling) is used, the chelating and sequestering agents hide the calcium/magnesium particles from the detergent molecules. The detergent molecules carry on holding onto the soils they have emulsified. This allows them to get more thoroughly rinsed from the carpet fiber.
Steam Carpet Cleaning: Procedure
- Get ready the equipment and supplies. In a pump or power sprayer mix free rinsing emulsifying pre-spray (comply with manufacturer’s recommended dilutions). In the solution tank of the extractor, mix the rinsing agent (follow manufacturer’s advised dilutions).
- Should there be a lot of furniture to remove, draw a floor plan.
- In case the area has furniture, remove as much as possible.
- Thoroughly vacuum carpet. If pile is crushed or matted, working with a pile brush will help loosen the soils which will make the vacuuming process more effective.
- Pre-spray an ample amount of the emulsifying pre-spray to an area 400-600 sq. ft.
- With the use of a grooming tool, agitate the pre-spray into the fibers and let sit for 10 to 15 minutes. (Make certain that it does not dry out.)
- Extract area with a portable, truck mounted extractor or an automatic carpet machine.
- Do again steps 5 to 7 until the entire area has been completed.
- Groom cleaned area.
- Replace any furniture that was taken out (place protective shields under any legs that may cause rust).
- Thoroughly clean up all equipment.
Intent behind Grooming
- It helps achieve full fiber contact.
- Begins soil suspension
- Assists in lifting crushed or matted fibers
