Lemon works great on removing just about any pen marks. (I've had great success with it removing the ink from a permanent marker from my kitchen table). So, I tried it on my computer screen. Just a drop or two on a Q-tip and problem solved. My screen was cleaned and best of all not damaged. So, there you have it. Use Lemon oil to remove pen from your computer screen.
