Encapsulation
Commercial carpets present
many challenges – this method may be what you are looking for.
It’s
a familiar story of commercial carpet cleaning:
You do a
fantastic job and are told the carpets have never looked better.
You go home
satisfied with a job well done.
The next
morning you receive the disturbing “morning after” phone call: “Something’s
wrong. The carpet looks worse than before you cleaned it!”
What
happened? Didn’t you do a good job?
Commercial carpet is just not the same as residential
Commercial
carpet is not the same as a carpet installed in a residential setting.
Those
handsome 75-ounce plush nylon carpets installed over 8-pound pads clean very
differently with hot water extraction than a typical commercial carpet in a
flat, glue-down construction.
With the
residential carpet, there’s plenty of airflow.
With
commercial carpet, there’s essentially no airflow, so hot water extraction can
become more challenging.
Commercial
carpets are often loop construction. The densely-packed loops can trap a
tremendous amount of dry soil.
A
considerable amount of commercial carpeting is olefin and olefin can be
difficult to clean.
There are a
number of reasons why commercial carpet can present a set of conditions that
could frighten even the most savvy residential carpet cleaners.
The road
to encapsulation
I started
Pioneer Maintenance in St. Petersburg, FL in 1982, and spent the past 21 years
in the commercial cleaning industry.
During the
past two decades my company tried every method of carpet cleaning. I kept
investigating different methods in my search to find a system that could produce
consistently good results.
I continued
my search because I found each of the methods in our industry fell short in some
area at one time or another.
My efforts
finally paid off.
We
presently maintain thousands of square feet of commercial carpet every day, with
a system that overcomes the common commercial carpet problems and produces the
kind of results we expect.
The system?
Encapsulation cleaning. (See “Benefits of a good encapsulation system” in the
sidebar.)
It’s a
low-moisture method that traps soil particles in suspension, drying to a crystal
and then vacuuming soils away.
We can now
service commercial carpeting and not have to worry about what the carpet will
look like the next morning, the next week, or even the next month.
Our carpets
are staying cleaner longer than they ever have before. Our clients are happier.
Our system is simpler and our techs love it. And we’re able to offer a fair
price and still maintain a decent profit. (See “Is it for you?” in the sidebar.)
Is this
the end of other cleaning methods?
At this
point I need to stop and clarify there are situations requiring using various
cleaning systems.
Encapsulation is an ideal method for the majority of commercial applications.
Yet encapsulation also has its limits.
We don’t
recommend it for grease impacted carpets. We find it works especially well for
maintaining what makes up 99 percent of commercial carpet. Encapsulation aptly
handles the “grayed-out” dingy commercial carpet with abundant drink spills –
that’s where it excels.
It’s
coming out of the closet…
Encapsulation is not just a solution that has worked well for our company.
Major companies throughout the country have begun recommending and using encapsulation for their commercial carpeting.
.
A number of the largest commercial carpet manufacturers in the country are recommending and/or using various forms of encapsulation cleaning to maintain their commercial floor coverings.
In the past
year or so there has also been a rapid influx of encapsulation cleaning products
produced by several leading manufacturers of carpet cleaning products. It’s
clear the industry is quickly becoming aware of encapsulation.
Why the
insurgence of interest in encapsulation? Simply, encapsulation successfully
addresses many of the problems commonly associated with commercial carpet care.
How
encapsulation works
This system
is built on new technology.
The better
encapsulation products we’re now seeing are built with new crystallizing
polymers. Whereas some of the old style carpet shampoos may have employed an
acrylic copolymer, the new products utilize new polymer technology that forms a
distinct crystal.
Some of the
new products also contain fluorochemicals.
Defining
types of soil to contend with in commercial carpet settings helps understand the
principle of encapsulation. While it’s true there are a plethora of contaminants
a carpet can be exposed to, on the most basic cleaning level we can narrow it
down to just two types of soil: Dry soil and sticky soil.
Most dry
soil in a commercial setting can be readily removed by routine dry vacuuming.
It’s the
oily and sticky soils that attract and hold dry soil to the surface. The result
is a dull, gray and ugly appearance.
The
encapsulation process does a wonderful job of counteracting the sticky soils.
The key to effective carpet cleaning is to remove the sticky soils. The
encapsulation chemistry surrounds soil particles in the carpet and forms a
crystal that can't attract other soil.
The
encapsulated soil particles release from the carpet fiber and are extracted with
normal vacuuming. And since there's no dirt attracting residue left behind, the
carpet is able to stay clean longer.
Agitation + crystallization = encapsulation
There are
two recommendations I make when it comes to encapsulation carpet care.
First, the
equipment: We’ve all learned we clean with TACT – temperature, agitation,
chemical and time. The encapsulation method utilizes all of these cleaning
elements. With encapsulation it’s vitally important to recognize the agitation
component of the cleaning pie. It is imperative the scrubbing equipment you
choose can scrub deeply.
Next, the
chemistry: Good crystallizing chemistry is important. With encapsulation it’s
critical the detergent forms a true crystal as it dries.
The level
of crystallization that occurs will directly affect a detergent’s ability to
hold soil. Crystallization is a primary part of what should be accomplished with
a good encapsulator.
As the
carpet is scrubbed the soil is released from the fiber and is now suspended in
the detergent. As the detergent dries it forms a crystal that breaks away from
the fiber.
The
crystals contain the encapsulated soil particles. These soil-laden crystals can
then be extracted from the carpet with vacuuming.
It’s
important to make certain the product you choose will form a true crystal. An
encapsulant’s ability to crystallize can easily be tested by simply drying a few
drops of the product in a dish overnight. The next day you should see a very
distinct, brittle crystal.
The cost of
this method is low. You generally spend less than .05 cents per square foot in
cleaning commercial carpet. Eight ounces of solution mixed with one gallon of
water will cover approximately 300 square feet, depending on conditions.
Encapsulation cleaning steps
The first
step is achieving the best possible pre-vacuuming.
Remember
that we want to remove the 79 percent of dry soils first. (See “Ratios of soils”
in the sidebar.)
As the
carpet is thoroughly scrubbed the encapsulator is applied and worked evenly
through the carpet fiber. It’s helpful to use the detergent’s foaming ability as
an indicator of how much solution is being applied to the carpet.
You simply
want to whiten the surface of the carpet; a heavy foam is not desirable.
Vacuuming can be performed at the next scheduled vacuuming. No rinsing is
required. Rinsing actually defeats the purpose of the encapsulation
technology.
Encapsulation is a simple, cost-effective way to maintain commercial carpeting.
The encapsulation method, when performed correctly, can produce extremely
pleasing results.
It’s a
win-win situation!
Carpets
look exceptionally good on a day-in and day-out basis. Recurring spots and
wicking problems are essentially eliminated.
Large areas
of carpet can be serviced quickly.
Since it’s
a low moisture system, carpets are put back into service promptly. And there are
no more haunting “morning after” phone calls.
Clients are
happy, funds are deposited, referrals are generated, and business is good!
