I can't get the mechanical pencil to come out. Must not be #2 lead. I made a white on white hand embroidered handkerchief for my DIL and the marks never came out. I have used everything I could think of. Oxi, Zout, peroxide, bleach, everything anyone suggested. At least the fabric and the embroidery are still there. I only use a regular sharpenable pencil now. I thought maybe it was because it was under the embroidery that it wouldn't come out.
