A wringer should be a part of the laundry equipment, and the best on the market is always the cheapest. After a wringer is used, it should be carefully dried and the screws pressing the rollers should be loosened. When not in use, it should be kept covered with a cloth to protect it from dust and dirt. The bearings should be oiled occasionally. Oil dissolves rubber, and that property of oil is taken advantage of in cleaning the rubber rollers. They are carefully wiped with a little kerosene which eats away a thin film of the rubber, exposing a fresh surface. The operation should not be performed frequently, however, and the oil should be carefully and completely removed immediately after its use.
