Wicking after Cleanng Carpet
Wicking is the upward motion of water and cleaning solution during drying from the base of a tuft to its tip carrying with it any remaining soil and contamination, which is then deposited on the tips of the tuft.
To reduce wicking, pre-vacuum thoroughly, make extra dry strokes, and use air movers.
The biggest cause of soil wicking is overwetting due to technician error. Soil wicking can be caused by slow drying, overwetting, overuse of pre-spray, and heavy accumulation of soil at the base of yarns.
Wicking is the cause of "reappearing spots and stains." Most of a spill is not on the fibers, but is instead in the backing. Drying time is critical to reduce this problem – use plenty of dry strokes and blowers, especially when working with heavily soiled carpet or berber.
Wicking on loop pile carpet can be greatly reduced by following hot water extraction with dry bonnet cleaning. This is especially helpful on commercial olefin loop carpet with a large number of spills. NOTE: Do not run a DRY bonnet on olefin (polypropylene) carpet or rug - olefin has a very low softening point!
Use Brown Out® to reduce wicking and re-soiling on carpet that has been improperly cleaned and is loaded with detergent residue. Our object in this procedure is to:
In this procedure DO NOT pre-spray the carpet or use any extraction emulsifier or detergent.
