Interim cleaning methods for textile flooring are
33powder cleaning (granulate cleaning),
33fiber/yarn pad cleaning,
33cleaning with roller brush machines,
Carpet cleaning powder (carpet cleaning granulate) is a moist
coarse powder (corn cob granulate or wood flour are often used)
with good dirt-binding properties. Its active substances contain
solvents (mostly alcohols) and surfactant solutions as active
cleaning substances. These days, however, surfactant-free carpet
cleaning powders are also available; these have the advantage of
reducing the resoiling potential of the floor. With powder cleaning,
dirt is captured in the carrier substance, which are later vacuumed
up. Because the carpet cleaning powder remains embedded in the
textile surface structure during cleaning and can no longer be
completely removed by vacuuming, this method is not suitable for
33rustic loop pile (Berber carpeting),
33woven flooring made of sisal or coconut fiber.
Cleaning with carpet cleaning powder leads to increased dust
in rooms, which means that these rooms must be
mopped more often. The increased dust formation can be
problematic for allergy sufferers! Professional cleaners use this
cleaning process less and less.
With the fiber/yarn pad procedure, fiber pad discs in combination
with one-disc machines are employed. Optimal cleaning results
are achieved when using fiber pads with machines that feature
eccentric rather than solely circular movement (classic one-disc
machines). Fiber pads made from active fibers and microfibers are
available. The fibers in microfiber pads are much finer than those
in active fiber pads. The fiber pad discs are dampened with water
and/or the floor is sprayed with aerosol.
Instead of water, surfactant-free detergents (like phosphates or
citrates) can be used. In many cases, however, no cleaning agents
are needed. Nearly all flooring can be cleaned with fiber pads.
They are ideal for loop pile, thick and thin velours; their cleaning
success with fiber-bonded flooring, however, is limited.
When using a roller brush machine, a suitable cleaning solution
(such as surfactant-free cleaners on complexing agent basis or
special cleaners that use encapsulation technology) is applied to
the textile surface and worked into it using a roller brush machine
with soft roller brushes. Depending on the machine type, the
dirty solution is vacuumed up by a transport system in the same
or by an additional vacuuming unit, which also enables
a two-workstep process.
If the brush roller machine has no transport system or suction
unit, residues are vacuumed up with a high-performance vacuum
brusher after the surface is completely dry.
For the dry shampooing method, dry foam is created with the
help of blowers or compressors attached to the one-disc machine
as accessories, and worked into the pile of the surface with the
After drying, during which the surface should not be walked on,
the dry crystalline particles of the shampoo that have captured the
dirt are vacuumed up with a vacuum brush. The dry foam method
is suitable for all textile flooring, but shampoo residues can lead to
faster resoiling and impair the factory-implemented impregnation
the carpet came with.
Before basic cleaning, loose dirt must be removed by vacuuming
or vacuum brushing. Basic cleaning also removes stubborn stains
or other residues that mar the appearance of the textile surface.
Fundamentally, basic cleaning is a wet cleaning.
Depending on their composition, textile floorings are more or less
sensitive to moisture and dampness. This makes it advisable to
test the planned cleaning method on a less visible spot first (such
as under a radiator). Before carrying out basic cleaning, the surface
must be thoroughly vacuumed with a vacuum cleaner or brusher!
Heavy wetting during basic cleaning can cause, for example:
33lack of fixation to the undersurface (e.g. due to the
emulsification of dispersion adhesives),
33discoloration/bleeding of non-colorfast textile floorings
(e.g. by the use of alkaline cleaners),
33stain formation through migration of natural dyes from the
basic fabric or subsurface (like with wood flooring).
Basic cleaning methods for textile floorings are
33combination: spray extraction/fiber pad cleaning,
33combination: wet shampooing/spray extraction.
Only spray extraction removes dirt that has penetrated to the
of carpet flooring. Here, after removal of loose dirt by
the cleaning solution is pre-sprayed onto the surface
with a pressure sprayer, which gives the cleaning solution some
time to penetrate it. Surfactant-free cleaning agents based on
agents are particularly suited for this because they
