So, I just managed to get a sofa from a facebook selling site. It's lovely, really comfy and fits the space just right.... But it's pretty dirty!
There are a few stains on it (blue-ish), which I am not sure I can get out. But the rest just looks like dirt in the creases of the leather. So, I am now after your top tips for cleaning the leather - I have googled and found massive contradictions, so am turning to the bible that is MN ;)
