My daughter's class uses dry erase markers and white boards on a regular basis, so she's constantly coming home with dry erase marker on her clothes (an errant mark on the front of a dress, smudges on her sleeves). So far, nothing I've tried has worked to get it off her clothes. I understand why her teacher uses them, but I'm frustrated at having her clothes ruined. If you've had success in getting it out of clothes, please share!
