Traffic Lane Gray is an uncorrectable condition that often causes carpet to "Ugly Out" long before it is "Worn out". This is caused by worn fibers failing to reflect light from the high traffic areas in the same way it is reflected from the other areas. this results in what appears to be soiled areas even though the carpet has been thoroughly cleaned. Dinge-Away Reflexive Enhancements are liquid sprays that adhere to and modify the reflexive properties of the damaged fibers. Carpets that have been declared "uncleanable" and that "must be replaced" can now be restored to serviceable condition.
