Remove sticker and tesar residues with alcohol
Since I do a lot of crafts and thus always hang a lot of things in our Fernster, sometimes there are left over adhesive tape leftovers. To remove these, I used a towel that is lightly soaked with alcohol.
Just rub a few times over the leftovers and they go off (on our plastic window frame works great).
It's best to test in an invisible area first, so that the surface is not damaged too much and everything looks even worse than before.
