How can I remove dark marks from cream/beige wallpaper without removing the colour?
I’m moving out of my apartment in a few weeks and noticed some dark marks on the walls in the living room. The wallpaper is cream/beige and I’d like to get rid of them without messing up the wallpaper.
They are quite thick in places, not even sure what they are from!

A dry sponge works on a lot of different marks. I used toothpaste on crayon marks on my daughters wallpaper and it left a dull spot. White bread sometimes works too. Read the article from Don Aslett the cleaning guru on HGTV. Good luck!
I would first start with toothpaste. apply it to the marks and wipe off after a minute or two. If that doesn’t work use Kaboom It works very well.
Good luck.
I would use a semi dry towel with diluted hydrogen peroxide. Don’t rub too hard just dab for a while and rub slightly. the catch is they will not go away completely … you want to made them look better and less noticeable so the catch is to not over do the cleaning… stop when it is much less noticeable.. If you over do it .. then it will look worst.
