How to remove furniture dents from your rug
Drop one ice cube into each dent. Let the ice cubes melt. As they melt, the nap of the carpet will begin to fluff back up, reducing (and eventually removing) the dent. Check the results the next morning. If necessary, blot up excess water with white paper towel or colorfast cloth. If the nap hasn’t recovered completely, use a fork to gently lift remaining carpet fibers.
Be careful if you have wood floors underneath. Test a less visible spot first to make sure moisture does not damage the wood. Do not use this method on hand-dyed rugs, antique carpets, delicate or valuable rugs, or on fibers not compatible with water cleaning.
