Stain on Light Grey Leather

[M.I.B]

Suspicious stain on the rear light grey leather seat - one lady ("Mrs....") owner with a couple of small dents in the rear seat base.

The Sherlock holmes in me says " kiddy in kiddy seat has spilt/produced something"

It is slightly orange in colour so I guess it is squash or juice.

Any ideas how I can:

A - get it out

B - give the seats a clean and feed - they are a bit dry and don't want them cracking.

Thanks
