Oily soils on Oleophilic carpet fibers

Oleophilic (i.e., oil attracting) carpet fibers (e.g., polyester, olefin) will absorb oily soils over time more than nylon, leaving a yellowish look on traffic areas that cannot be removed with normal cleaning. However, with proper professional pretreatment and with maximum application of the principles of cleaning, oily oils can more effectively be removed from Oleophilic carpet fibers.
