The carpet should be inspected and tested so the technicians can inform the expected results and any potential challenges. This inspection should include identifying the fiber type as well as any potentially permanent stains.
Up to 85% of soil in a carpet is dry particulate soil that has bonded to the surface. Household vacuum cleaners do not always remove all of the dry soil. If not completely removed, it may “wick” back upon drying.
In this step, a solution is applied that loosens the soil and spots for more effective removal.
Some spots require special solutions and special care for complete removal and to avoid the stain“setting.”
The carpet is gently massaged to further loosen the soils so that aggressive, harmful cleaning is not needed.
Now that the soil has been properly “suspended,” it can be extracted without over-wetting or leaving a sticky residue behind.
A common problem is that some carpet cleaners do not neutralize the carpet. Not balancing the pH can cause the carpet to be stiff and attract dirt like a magnet.
Stubborn stains sometimes require specialty stain removal processes. Because many cleaners do not train themselves, they do not know about these processes.
The pile of the carpet should then be “finished” so it dries and cures in the proper direction.
Proper drying should be insured with high velocity airmovers.
A thorough walk-through is done to insure that the customers are completely satisfied with the cleaning job.
