RUG CLEANING METHODS
TRADITIONAL HAND WASH
This procedure is the most labor intensive. A rigorous vibra vac
back and front to dislodge the deeply embedded soil particles, followed
with a pre-clean conditioning for protein based spots. After sufficient
dwell time with pre-conditioners, a rotary shampoo process is employed
to break down bonded oily soils suspending them for extraction. The
last steps are a thorough conditioned rinse extraction, this is a low
pressure, hi volume rinse wash followed with suction extraction.
Ideally the rug is clean of all residues including cleaning detergent
residues. Rugs are then transferred to a controlled dry down phase with
circulating air currents.
This process infers "steam", water temperatures above 212 degrees
Fahrenheit. The higher the water temperature the more efficient and
effective the cleaning will generally be, is the common logical
deduction. It is not quite this simple. Efficient in terms of speed
and production is indeed true and in certain conditions it is
preferred. However, woolen and cotton rugs should not be cleaned with
temperatures above 160 degrees Fahrenheit, more than adequate for
effective cleaning, yet not damaging to the structure of the woolen
fiber. Synthetic rugs, nylon, olefin and polyester are indeed qualified
for steam cleaning, yet it might be noted that the weave structure
usually will have a jute or cotton weft component. Each rug should be
carefully examined before high temperature "steam cleaning" is employed
to avoid shrinkage or warping issues.
HOT WATER EXTRACTION
This is simply using the steam cleaning equipment process but
controlling the water temperature at set points suitable to the rug
construction. It is simply a flush and extract process, relying on
detergents to breakup the soils and whisk them away under constant
vacuum and flushing.
The shampoo process requires a thorough vibra vacuuming, followed by
a rotary shampoo scrubbing of the rugs pile. The remaining shampoo
detergent and soil residues will coalesce and dry in to a powdered
residue that is then vacuumed out of the rugs pile
A detergent based high density foam that is jetted into the rugs
fiber, breaking up soil contaminates, then left to dry and vacuumed away
or better, rinse extracted leaving the pile free of detergent residues.
DRY POWDER CLEANING
This process is indeed non-water cleaning but requires a
pre-conditioner to be sprayed into the rugs pile. After a dwell time it
is followed with a powder that is solvent bearing and mechanically
brushed into the rug pile. After 30 minutes dwell time the rug is
vacuumed. The process may need to be repeated depending on initial
MOR MACHINE CLEANING
A semi-automated electro mechanical washer scrubber is used in this
process. The rug is pre-conditioned and fed into the auto scrubber,
which injects high volumes of water and detergent under pressure with
associated mechanical brushing. The rug is rinsed and placed in to a
centrifugal wringer to spin out the excess moisture. The rug is then
transferred to a dry room where it is hung with circulating conditioned
air for drying.
A process where by the rug is immersed in a containment pit and
allowed to "soak in" thoroughly. Hand scrubbing and power flushing
removes all contaminates and bonded soils. The rug is then squeezed
with a weighted roller to remove excess moisture and transferred to a
centrifuge to spin out remaining moisture, then transferred to a
conditioned dry room.
