The majority of oriental rugs use acid fast and natural rug dyes. When adding the white vinegar to carpet washing water, the solution is given a higher acidic rating, which strengthens the bond between the dye and the fibers of the rug. This process creates better protection against color running or fading.
Whether a liquid spill or a pet accident involving solid matter, always finish by sponging the area with cool and clean water. Absorbent towels or a non shedding brush is best for this part of the process, though a soft bristled brush may also be used.
Push in the direction of the nap, but bear in mind that scrubbing too hard could cause the fibers to loosen. Towels should be placed under the rug to keep the underlying floor and any padding from soaking up the water (though we do strongly suggest that you remove the under pad before you begin cleaning your rugs).
Be sure that the backside of the rug is completely dry, before removing the towels…. both the nap and underlying side of the rug should both be thoroughly dry.
