Steam cleaning method involves hot water being fed to a spray-extraction tool or wand, coupled with a pump-vacuum power unit. The cleaning solution is injected under pressure into the carpet through water-jet nozzles. In fact, this water gets into the fibers all the way down to the primary backing.
The process loosens:
- embedded soils
- removes oil and grease deposits
- as well as re emulsifies detergent residue
All of which is immediately extracted by powerful vacuum systems.
There are many types of steam cleaning carpet cleaner on the market. Ranging from small portables up to the extremely powerful. Definitely effective truck-mounted units. The principle is similar to whether using a portable or truck mounted unit. Hot water or solution is injected into the carpet using high pressure. Then extracted almost instantly. Removing soils, residues. Including spots and some stains.
The truck-mounted units are made so only the hose and wand are taken into the building cleaned. These incredibly powerful steam cleaning units deliver hot water and generating a high vacuum recovery. They are 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, very proficient at high production with less residue. As long as the proper chemicals are used and the operators are adequately trained for carpet maintenance.
Two methods when steam carpet cleaning:
1) First, it involves a traffic lane cleaner sprayed onto the traffic lanes and agitated into the fibers. Each area is then cleaned by hot water extraction. It has a cleaning solution injected into the fibers through the wand. This method isn’t going to rinse the fiber. Surely leaves more cleaning solutions residue behind.
2) The second method involves a free rinse along with emulsifying pre-sprays. Definitely sprayed over the entire carpet. This is then agitated into the fibers then areas are extracted with a specially formulated rinsing agent. Injected into the fibers through the wand. Likewise, this method works more effectively at achieving a cleaner fiber.
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 rinsing capacity enhances by:
- Neutralize any alkalinity contained in the pre-spray
- Lock migrant dyes back into the fibers
- Ceases soils from redepositing back onto the fibers.
When rinsing carpet fibers with plain water, calcium/magnesium particles contained in the water cause the detergent molecules to drop the soils emulsified. These detergent molecules then begin emulsifying the particles. The soils redeposit back into the carpet fiber thus bringing about resoiling.
Tip: When the rinsing agents are 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 more thoroughly rinse from the carpet fiber.
Steam 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). Mix the rinsing agent (follow manufacturer’s advised dilutions) in the solution tank of the extractor.
- In case the area has furniture, remove as much as possible.
- Thoroughly vacuum the carpet.
- Pre-spray an ample amount of the emulsifying pre-spray
- 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.
- Repeat steps 5 to 7 until the entire area is completed.
- Groom cleaned area.
- Replace any furniture taken out. Place protective shields under any legs that may cause rust.
- Finally, thoroughly clean up all equipment.
