Kilims are similar to hand knotted rugs in that they require very little maintenance to keep them in good condition and appearing as vibrant as they were when they were first woven. Regular vacuuming (without a beater bar), regular inspections (looking for any wear, holes, damaged edges, or signs of moths or carpet beetles) coupled with periodic professional kilim cleaning is all that is required.
The first step we take when professionally cleaning a kilim or a rug is to do a color run test in a small discrete area. This color run test helps us identify which kilims and rugs are too risky to clean. While the risk of color run can never be eliminated entirely, a color run test is a great tool in helping us manage poor dyes that can run during a cleaning. The next step is to brush the kilim with soap and minimal water to ensure that all dirt or particles that can be embedded within the kilim's warp and weft are dislodged. Next, the soap is removed from the kilim. The cleaning is followed by a thorough drying - a critical step to ensure that the kilim will lay flat and will not lose its shape. Undertaking a professional cleaning such as this every two years or so will help ensure that a fine kilim can be enjoyed for decades to come - if not longer. --www.traditionalrugrepair.com
