If you live by a feed store, I am sure you can find this wonderful product called, "Orvus." It is used to cleanly and safely wash animals. It has no harmful products inside and is safe to use on your clothes and all quilting materials. A lot of professional quilt appraisers suggest using this products to clients and museums for quilt care. A little bit goes a very, very long way, and this product is usually sold by the gallons, so split the cost and share with other quilters! I just use a tablespoon or so for a large load. Very cost effective and safe...also environmentally safe, no phosphates.
