Rule of thumb. Never dry something in the dryer if it has a stain on it. The heat sets the stain in. What I do is spray with Oxi Clean and let it set a few minutes. Put a drop of Dawn liquid on it and rub it in then throw it in the washer. It works like a charm. Took ink out of my husbands shirt, grease and hydrolic fluid out of his clothes, blood out of clothes. I haven't run accross a stain yet that I haven't been able to get out. If the stain doesn't come out in the first washing I do not dry it in the dryer and hang it up to dry. Next time I do laundry I treat it again. Marker usually takes about three washings to come completely out but it will come ou.
