How do you get permanent marker stains out of white clothes?
Try to treat with a bleach pen. Apply bleach pen directly to the stain and wait a minute or two before laundering. Don’t let it sit for too long before washing (like over a 1/2 hour or so) or the stain will yellow. Then launder with cold water. Inspect the stain and let hang dry. If stain is out, great! If not, try the bleach pen again. If it doesn’t come out the second time, it most likely won’t. I did this on my nieces pants and my sister’s track suit and it worked fine. Also, my sister had already washed and dried her suit before noticing the pen and coffee stains on the white part of it!!! Hope it works for you!
