A shag rug traps soil deep in the pile and can distort if brushed or soaked too aggressively. Cleaning should start dry and add as little moisture as necessary, with the fiber and backing in mind.
Remove dry soil without pulling the pile
If the rug size allows, shake it outdoors. When vacuuming, use moderate suction and avoid aggressive rotating brushes that can wrap around or pull long fibers.
Blot spots from the outside inward
Blot liquid instead of rubbing and use a cleaner compatible with the fiber. Working from the outside toward the center helps prevent spreading; press with clean towels to remove moisture between applications.
Keep the backing from becoming saturated
The backing can take much longer to dry than the tips of the pile. Over-wetting during whole-rug cleaning can cause odor, distortion, or adhesive damage even when the surface feels dry.
Use professional cleaning for delicate or heavy rugs
If the label calls for specialty cleaning, color transfers during testing, or the backing would be difficult to dry at home, controlled professional cleaning reduces the risk of shrinkage and moisture marks.
