I use a whole bottle of hair spray. In my dryer, I can hand turn the drum until the ink is at the bottom and then use paper towels to mop up the hairspray after letting it sit on the ink for a bit. Take frequent breaks since the fumes can give you a headache. Hope you have a light when the dryer door is open as it makes it easier to see where the ink is. I get as much ink off as possible and then wash and dry a load of towels before using it to dry clothes again.
Depending on the ink, you can try nail polish remover as well.
