Hi there. Try AutoGlym www.autoglm.com
The Leather Cleaner and Leather Care Cream is used by:
Aston Martin Lagonda Ltd
Jaguar Cars Ltd
McLaren Cars Ltd
Morgan Motor Co Ltd
As you see, the owner of Volvo is listed there.
AutoGlym also has the Royal Warrant:
By Appointment to Her Majesty The Queen
By Appointment HRH The Prince of Wales
AutoGlym is not cheap-but it does work and is always highly recommended.
I use it and found it excellent.
Just a thought
Cheers
