Left the permanent marker out? Toddlers get a hold of it??
(This is usually only a mistake you make ONCE...)
Here are some tips to getting the marker out of different materials:
1-Clothes - use hand sanitizer
2-Walls - use toothpaste or hairspray
3-Wood - use rubbing alcohol
4-Carpet - use white vinegar
5-Dry Erase Board - use dry erase marker
6-Furniture - use milk (just make sure then you clean the milk out so it doesn't get spoiled - stinky!)
I will admit that I haven't tried any of these - but if you ever get in this situation...what do you have to lose, right?!?
