Blot the oil stain with a clean white cloth or paper towel. Do not rub; instead lift the cloth or towel gently up and down, pressing into the stain.
Lay the quilt on a hard, flat surface, such as a table.
Place an absorbent white towel beneath the quilt, under the stain, as protection against treatments that soak through all layers of the quilt.
Pretreat the oil strain with a pretreatment spray. If no pretreaters are available, mix powdered laundry detergent with just enough water to create a paste. Apply the paste directly to the strain.
Allow the pretreated quilt to sit for the amount of time recommended by the manufacturer, or about 10 minutes.
Launder the quilt in the hottest temperature that's safe for the quilt fabric, using a large load’s worth of laundry detergent. Be sure to use the gentle cycle, and face the pieced side of the quilt away from the washer’s agitators.
Examine the quilt when the washing cycle is complete. If the stain remains, pretreat and launder again, or try another grease removal method.
Apply a dry-cleaning solvent to the stain. Allow the solvent to evaporate.
Apply a mild hair shampoo to the stain. Allow it to sit for about 10 minutes.
Launder the quilt in the hottest temperature that's safe for the fabrics in the quilt, using enough laundry detergent for a large load. Set the washer to the gentle cycle, and turn the pieced side of the quilt so it doesn’t face the agitators.
Examine the quilt when the cycle is finished. If the stain remains, repeat the dry cleaning solvent and shampoo treatment or try another stain removal method.
Mix a little washing soda (found in the laundry aisle; washing soda is not the same as baking soda) with warm water, forming a paste.
Apply this mixture to the stain, and allow it to sit for 10 to 15 minutes.
