After months of preschoolers with markers, slime, play dough, wet nail polish, and of course, food on my dining room chairs, I couldn't stand them anymore. (The chairs, not the kids! lol) I really needed to try to get them clean, and prefer homemade remedies to store-bought chemicals. I found this recipe posted on http://do-it-yourself.tribe.net/thread/480e9776-2d06-4ecd-b0cf-bd4fbd56d307 by Meander. I immediately tried it and it worked miracles! The nail polish wasn't affected by it, but everything else from chocolate and spaghetti sauce to colored markers came out with very little work. In fact, my 5 year old did most of the scrubbing with a small manicure brush. Remember to only use the foam, not the liquid at the bottom of the bowl, and the chairs will dry out quickly.
