Carpet Cleaning Methods
|
|
|
|
Hot
Water Extraction (HWE)
|
|
|
After the preconditioner
is applied through a pump
sprayer, in-line
sprayer or rotary shampoo machine, it is flushed
from the carpet, along with the soil using a detergent
and either a portable
or truck
mount. This process can be repeated several times
depending on how heavily soiled the carpet may appear
to be.
It is recommended that heavily soiled carpet may need
several flushing passes, followed by overlapping extraction
only passes. Carpet should be completely dried within
6-8 hours, not exceeding a 24 hour period. Multiple
extraction passes, good ventilation and air
movers can help to speed up this process.

Encapsulation
|
|
| This
method of carpet cleaning is becoming more and more
popular in commercial carpet maintenance. It should
be used as an interim maintenance method and should
be followed periodically (every 2-3 cleanings) by a
thorough hot water extraction.
The encapsulating chemical (a liquid cleaning agent) is sprayed on and then brushed into the carpet using a cylindrical or rotary brush
machine or bonnet. The encapsulation chemistry surrounds each soil
particle and crystallizes it so it can't attract other soils. The
encapsulated soil particles release from the carpet fiber and are
removed by normal vacuuming which will generally be done by the
janitorial staff at regularly scheduled times.
Since its a low moisture system, carpets can be put back into use
promptly. This process allows maintenance companies to provide a
continual high level of appearance at a lower price than other
traditional methods while generating high levels of productivity.
Encapsulation is designed for commercial maintenance only. |

Shampoo
|
|
| A
high-foaming
carpet detergent is applied to the carpet though
a shower
or channel-feed, nylon bristled brush at a speed
recommended by the manufacturer of the equipment in
use, safe for the carpet that is being cleaned. The
agitation of the brush on the surface of the carpet
creates a foam that pulls the soil from the carpet.
Depending upon the detergent used, either a wet
vacuum extracts the soil upon drying or other detergents
require that detergents are dry vacuumed. A preconditioner
may or may not be used prior to application. |

Absorbent Pad (Bonnet Pad) |
|
Dry-solvent based or carbonated or non-carbonated water-based carrier is sprayed onto pad and the carpet. The pads can be square or round and may contain fabrics such as cotton, rayon, synthetics or any combination. Instead of spraying, the pad can be dipped in a bucket of cleaning solution. During the agitation (spin buffing/oscillating) phase, the bonnet (pad) will attract and absorb the soil from the carpet. It is the job of the technician to monitor how dirty the pad is getting to replace or flip it as soil accumulates for maximum soil removal. A preconditioner may or may not be used prior to application. |

Dry Foam |
|
|
| Dense
foam, produced by a dry foam machine through
mechanical aeration of a liquid detergent is distributed
and agitated via machine brush action. The soil
within the carpet and foam is then extracted by
wet
vacuum or using the same machine. A preconditioner
can be used prior to application. |
|
|
|
|
Absorbent Compound |
|
|
|
Normally incorporates the use of an organic
or synthetic carrier that contains detergents,
solvents and some form of moisture.
This compound
may be preceded by a preconditioner and spread
on by hand or a machine specifically designed
to apply absorbent compound.
Brushing is used to spread and agitate the
compound evenly so that is absorbs the suspended
soil. After the compound dries, it is removed
by dry
vacuuming.
