Leather sofas

[allthegoodnamesweretaken]

DD has got yoghurt on the leather sofa. I didn't have time to clean it off at the time and now it is properly stuck on. It's not coming off at all. NOT EVEN WITH A BABY WIPE.
Two things, why on earth is the yoghurt so hard to shift? And how the flip do I get it off???

A bit of water over it to rehydrate the yoghurt (maybe use a damp cloth to cover it for a few minutes if it's not on a horizontal bit) and then it should wipe off. If it doesn't all come off after first 'soak' then repeat.
