Spray the rags with a pre-wash stain removing liquid. Make sure all oily areas are completely dampened by the pre-wash liquid. Allow the pre-wash liquid to remain on the rags for an hour.
Wash the rags in the washing machine with regular laundry detergent. Use the "Heavy Wash" setting and hot water. Add 1 cup of white vinegar to the rinse cycle.
Dry the rags in the dryer on a setting suitable for the type of fabric the rags are made from.
Things You Will Need
