I have had a new kitchen fitted and the install team have left marker pen on the splash back that I cannot remove. I have tried flash, baby oil ( recommended not just a stab in the dark!) and even WD40. What will get rid of it?
There's a product called Zoff which is for removing the marks left by elastoplasts on skin, that will definitely get it off but I stress test it somewhere inconspicuous first. You can get it from chemists.
If you draw over the mark with a dry wipe marker, the chemical that makes allows it to be rubbed off attacks the permanent marker. leave it to dry for a few seconds and you can just rub off with ease.
