Alcohol seemed too risky for me. My two and a half year old just did this to my lcd computer screen. I know alcohol gets sharpie out of couches and carpet… but I went first for the solution and cloth we use to clean our large flat screen tv. We got it with the TV. It is labeled Vizio screen cleaning kit. Worked like charm and I know it is safe. … and so is my daughter. Who is mad at me for putting her in time out while I figured out how to clean it. 🙂
