Recommended carpet cleaning process
Vacuum frequently. By vacuuming carpet you remove
damaging grit that wears down carpet it also removes soils before they build
up. I still prefer a bag based vacuum over a bag less and a well made
lighter unit. My personal choices are a Sanitaire for work and a Riccar for
home. But really most issues are from having an older broken unit and even a
new 60.00 vacuum will beat an older poorly maintained unit.
Truck mounted steam or hot water extraction (same thing) is
recommended once per year. Hot water extraction is the proper name for steam
cleaning and the industry has been trying to change it for years but it is
the same thing. Its actually hot water that hits the carpet not steam and
its extracted through a strong truck mounted vacuum not left on the carpet.
So the name makes sense its just not in full use yet. And truck mounted hot
water extraction is a pretty big mouthful.
So what is the recommended
carpet cleaning process? The cleaning industry allows numerous cleaning methods
so does not discriminate. To get a quantitative answer we must go to the
carpet manufactures websites directly. They have the most to gain as
they are protecting their product. While some list processes other then
steam they are the smaller carpet manufacturers which generally make specialty rugs
and not wall to wall residential carpet. There are 3 carpet
are responsible for about 90% of all US carpet, so they are the three to pay
All three recommend hot water
extraction (steam) as their preferred method. Here are the links to the actual
carpet manufacturers to see
(calls it deep cleaning).
The carpet and rug institute (CRI) which was founded by carpet manufactures
developed a standard for carpet cleaning and maintenance and can be
found here CRI 205 standards
document only mention HWE as a cleaning method and wants all chemicals to be
rinsed/extracted which is my method.
