Heavily soiled fringes, especially those with oily, greasy, parking lot or kitchen oils should be pre-treated with Sublime to liquefy oils and break oily bonds, spray apply or brush on Sublime to fringe, knots and kilim strip. Since Sublime is an anhydrous solvent, it should not be damaging to rug pile yarns, but avoid pile yarns so you do not end up with a cleaner end on your rug. Allow one or two minutes of dwell time, then use one of the techniques listed above to complete cleaning. If fringes still look bad after cleaning and drying, Fringe Whitener can make them look better and whiter.
Fringe Whitener covers over discolorations without damaging the cotton fibers. Some rugs have fringes that are henna, antique or tea dyed.
Sometimes this color is removed during cleaning. You can replace this color loss with Tea Dye, or use it when white fringes are not wanted by your customer
