Without further ado...how to get permanent marker off wood furniture and floors WITHOUT a magic eraser:
You'll need a toothbrush, some liquid comet scratch free scrub or other scrubby cleaner, a damp cloth, and a dry cloth.
Here's one chair with my son's handiwork (which is surprisingly good for a 2 year old!):
1. Put the comet onto the sharpied areas.
2. Rub it in with the toothbrush. You'll see the permanent marker coming up almost instantly.
3. Wipe it with the damp cloth and then the dry cloth. (You'll have to rinse/wring your damp cloth after doing a few spots...or just wipe it down and go back over all the chairs with a new cloth after they're all clean like I did.)
4. Go ahead and polish your furniture with Pledge or Liquid Gold so that it gets some moisture back.
Yay! Permanent markers begone! You're welcome. ;)
