Recently, I used permanent marker mistakenly instead of white-board marker. How to remove this writing?
1. If the writing is a few words or letters, you can use whiteboard marker (of any color) to write on the letters written by permanent marker. Then you can use clean cloth the remove. Now all will be gone.
2. If you have written the whole white board and you can use the first method, you can use fallowing procedure.
You can use pencil eraser to remove the writing.
3. Use Acetone. Acetone (250 ml) can be bought for about 2 USD. Use a pure cotton cloth and dip in acetone so that the cloth become wet. Then, gently rub on the board where the marker is written. This will clean the board completely. Make sure that acetone bottle is closed tight. Otherwise, it will evaporate quickly. You can use tissue papers too instead of a cloth.
4. You can use any alcohol and use method 3 by using a clean cloth.
