When I was young I had a whiteboard in my room to plan out the month. When I was young and did not use an agenda yet this worked great. Over the years I started using an agenda and stopped using this whiteboard to plan. I still used the whiteboard to write small things or to pin down papers that I wanted to keep for a while.
But the whiteboard did not look so good anymore because some of the black lines scratched of but not everywhere. So I decided to take of all the lines.
This was a lot easier than I thougth. I started using a knife but quickly found out that it made scratches where I did not want them. So I tried some soap with sand in it. Which also did not work.
As a last idea I used a brillo pad which worked perfectly. It did not make scratches but got rid of the unwanted lines.
And it worked perfectly.
If you have permanent marker lines drawn on your whiteboard, they can usually be removed easily by scrubbing over them with a dry erase marker. The dry erase marker will loosen the permanent marker, and it can be wiped away.

In this case is was not permanent marker but a line that was more like a sticker on top.
But thank you for the tip.
