I go with the hairspray also. It took sharpie off a linen jacket of mine years ago. Tell you what. I have a mark on a table right now. It is old and I never bothered to get it off, let me try and see what happens. Be right back
Yep, that mark has been there for about 6 months. It took some scrubbing, but some aerosol hairspray and it came off and did not hurt the wood.
