PRACTICAL CARPET CLEANING
At this stage you will have a reasonable knowledge
of your cleaning machine and suitable chemicals to
achieve the best results. If you have carpet
cleaning background knowledge or you have
attended a Prochem Training Course, you will
also have an understanding of carpet construction,
types of fibres and related problems. The following
is a summary of the techniques using your
Prochem Soil Extraction Machine.
Using the cleaning wand
The procedure for using the carpet wand will vary
slightly from carpet to carpet depending on profile
and soil content. The effect of using a lightweight
wand as a scrub wand is to introduce a certain
amount of mechanical agitation that undoubtedly
helps to clean better by agitation of the pile fibres.
On the majority of normal soiled carpets no pre-
spray cleaner will be necessary (except in problem
areas) and a normal mix of 10 ml. S775
EXTRACTION PRO per litre of hot water can be
used. Prochem can advise you on the various
alternative systems and methods that can be
applied for varying soil conditions and carpet types.
These are all referred to in the Prochem Training
Course Manual that is supplied with the course.
PREPARATION & FINISHING PROCEDURE
Clear area of all small items and breakables then -
1.
Dry vacuum (dust removal) open areas of
carpet - before moving furniture.
2.
Move all furniture to areas that you have just
vacuumed.
3.
Dry vacuum remainder of carpet and edges
(optional depending on condition).
4.
Pre-spray heavily soiled areas and treat spots
and stains.
5.
Clean carpet using cleaning method as
described below and subject to dye bleed test
being carried out.
6.
Reset pile with carpet pile brush.
7.
Replace furniture in original position, placing
Prochem waterproof carpet protectors under all
legs and feet of furniture.
8.
Use Prochem foam blocks under PLINTH
furniture to allow airflow.
When using the carpet soil extraction cleaning
method, there are certain basic rules of operation to
follow in order to achieve the best results and to
avoid over-wetting the carpet. The following is an
effective wand cleaning technique -
1.
Switch on pump and vacuum.
2.
Starting at right hand corner, extend wand
approximately 18" in front of operator to the
base of the skirting board.
3.
Operate solution trigger to apply spray cleaning
solution whilst simultaneously drawing back the
wand toward the operator thus allowing the
Steempro Manual.doc 1/8/09
vacuum nozzle to extract the emulsified soil
and excess moisture.
4.
The distance on this movement needs to be no
more than 18". Release the solution trigger to
stop spray.
5.
The wand is then pushed back over the same
path giving the vacuum a second chance to
retrieve more moisture.
6.
DO NOT apply more solution during the
vacuum only pass.
7.
The wand head is now moved far enough to
the left so as just to cover the left-hand edge of
the first cleaning pass and the procedure is
repeated.
8.
Spray and vacuum then on return pass,
vacuum only.
9.
Carry out a total of 4 spray and vacuum passes
overlapping each one by approximately 1".
10. At this point the wand head is passed back
over the area cleaned, using the vacuum only
to recover excess moisture.
11. When sufficient carpet has been cleaned and
vacuumed, the PILE can be reset using a
Prochem Pile Brush lightly brushing the pile
toward you as you move backwards.
The speed at which the wand head is drawn back
on the cleaning stroke is usually governed by the
degree of soiling, for example, the slower the
cleaning stroke the deeper the penetration of
cleaning solution. The same effect, however, can
be achieved by several quicker passes and not
allowing the cleaning solution to penetrate too far all
at once, and at the same time, using the movement
of the wand to agitate the cleaning solution which
does help to produce a better cleaning result.
The choice of technique is left to you, but it must be
pointed out that when using the slow technique,
there is a danger of wetting down to the backing of
the carpet and thereby risking a shrinkage problem.
Certainly, on all light to moderately soiled areas of
carpet, the wand movement should be fairly fast to
avoid over-wetting and extended drying out.
Remember that in the early stages of getting used
to your extractor, it is far better to re-clean a
patchily cleaned carpet than to have a bad
shrinkage problem on your hands. You will be
surprised how quickly you will master the cleaning
techniques.
If you have under-estimated the degree of soiling in
a carpet, you can always revert to one of the heavy
soil cleaning operations such as pre-spraying with
S709 MULTI PRO.
NEVER FORGET - a few extra minutes spent on
preparation and pre-treatment can save you
hours on a return visit.
