Because of dense pile construction of area rugs, dirt particles work their way down through the fiber, to the foundation of the rug where they cannot be removed by ordinary vacuuming.
This loose grit wreaks havoc on you rug’s delicate fibers, causing a cutting abrasive action as you walk on the rug. This is called abrasion. Abrasion accounts for fiber loss and embedded soil stains.
Spot and Pre-Conditioning Treatments
After dry soil removal, spot and pre-conditioning treatments are applied. It is important to pre-condition so that oils and spots can be easily removed.
The difference between a spot and a stain…
A spot is a foreign substance in the fabric that can be treated and removed.
A Stain is something in or on the fabric that has added a dye that cannot be completely removed.
