I made my daughter a cedar lined hope chest about 5 years back and about a year ago her daughter of 2 years old thought it was a good idea to decorate the top with a black sharpie. The original finish is stain with spar urethane and I am looking for recommendations on removing this art work without having to strip off the entire finish. The only thing I can think to do is to wet sand the top and reapply urethane. any other thoughts.

Sorry, no answers here, but a bump is a bump. Also, you may have better luck if this was a forum question. And the word “help” in the title has worked for me in the past. Have you tried “Goof Off”, or Xylene?

I don’t know if this will work on spar urethane, but when people use permanent marker on dry erase boards, (I travel for my job and see that more than you would think) I get it off by marking over top of the existing marks with a dry erase marker, then quickly wiping off. The solvent takes a second or two to evaporate and returns the permanent marker to the original state when it left the marker. You can mark over a small area at a time then wipe off, but not the whole top it dries too quickly.

You might also try denatured alcohol. It removes permanent marker. It shouldn’t affect the poly, but try it in a test spot first. If the marker hasn’t worked itself into the poly, it will wipe right off. Should make it easier to fix any spots where it doesn’t come off the finish. I make a lot of stuff for family and friends with kids, so I’ve been through this before.

Get a can (not bottle) of original Coke. Pour a little bit on let set for 1 or 2 minutes, wipe off and rinse. I observed someone do this before at a workshop a couple years ago. I do not know what the what finish was. But the it worked just fine.

Good luck

I use sharpies for labeling glassware in the lab and remove it after washing the glassware. I can tell you that alcohol won’t remove black sharpie but it will remove blue or red. To remove black you need acetone. It’s available in the paint section of any Home Depot or Lowes. Put it on a rag and rub the marks off. If you use a light touch I think you may get away with it without damage to the polyurethane. If it does fog the existing finish I think you’d be able to apply one more finish coat on top of it to clear it up.

Speaking of acetone, the wife’s fingernail polish remover is acetone.

Funny follow-up. Just 2 weeks after the conversation above my 3 year old daughter scribbled all over our kitchen table with magic marker, and water wasn’t removing it. I had refinished this table with polyurethane a couple of years ago. This wasn’t sharpie in this case, but acetone on a paper towel took it off fine. Doesn’t seem to have harmed the finish.

That’s one of the things about polyurethane—it’s just about bullet proof!
