Beat the rug till no more dust flies from it, then lay it flat on the floor, and spread over it, powdered fuller's earth. Rub the powder in with a brush as if you were scouring, and then roll the rug up, and leave it for a week before brushing and beating. When well beaten and swept, take a dishpan half full of water, to which add a cup of ammonia, and dipping a broom into the pan, sweep with the broom, the wrong way of the nap. This will leave the rug looking fresh and clean.
