T350 Prototype - Solvent Abuse!

[tvrtuscans]

I have just aquired the T350 Pre-Production Prototype. I want to retain the originality of the car and want to simply clean the interior and remove marks to the leather and vinyl trim. Can anyone suggest what solvents I can safely use to clean and remove marks from leather and also from vinyl...it also has old glue marks here and there.

Many thanks in advance.

Cheap stuff like autoglym leather cleaner has got a couple marks out for me, makeup from a girls hand is regularly making an appearance, easily dealt with
