Hello Goss,
I use the same as on the seats which is generally 'Dr Leather' wipes. These are quite sizeable and appear to clean better than standard leather wipes. I also have some proprietary 'Jaguar Leather Cleaner' which I was given and reserve for occasional use, but I find it leaves a slightly sticky residue. I am not a 'Detailer' so I am sure there's much better advice around than from me
As for your dealer's service, yes there certainly still seems to be plenty of useless ones around even amongst main dealers
