This'll sound really basic but we've only ever had wallpaper until recently!
Our hallway has been plastered and nicely painted a couple of months ago. My 5 yo nephew has left a few finger smudges on the wall... I'm sure there's a quick fix, my DH is going nuts - don't worry I've already told him to chill!
How can we get rid of the smudges without damaging the paint? Warm soapy water?
