Best product to clean up trashed leather seats?

[Hereward]

I need to tackle 6 years' worth of detritus that my children have built up in the crevices around their back seats; festering sweets, welded-on chocolate, mummified raisins and various other unidentifiable substances.

Can someone please recommend a spray or solution that I can clean the leather with, thank you.

LTT Solutions....and some time along with a warm garage.

I've always used the Gliptone Cleaner and a soft nail brush to agitate all of the dirt out of the cracks etc. Then a warm, damp MF cloth to wipe down. Then Gliptone Conditioner to soften the leather.

People are going crazy on Detailing World at the moment about Dr Leather wipes.
£22 for 150 wipes I think.

The best thing for cleaning leather seats is.........hard graft matey! No way around it unfortunately.
