Always read and follow the care instructions and any warnings on the garment label. And, follow the General Rules for washable fabric stain removal.
Use a soft eraser to remove what excess lead you can. But, be careful so you do not damage or stretch the fabric.
Spray the stain with a pretreatment product.
Rub the area with a heavy-duty liquid detergent. Rinse and launder.
There are also commericial pencil mark removers available in some quilt supply stores.
