If you want to reuse your driftwood, I wouldn't recommend you using a solvent even though I know that the acrylic one for our molecule pen is dissolvable in rubbing alcohol. But what you can do for what is it take sandpaper and you rub it off. So I've really rubbed off the bottom of the entrance stroke for the F here. So you can do the same for the exit stroke. And you can see that it was thought to come on. Yeah, just be patient.
