Most furniture shops should have the proper stuff to clean suede. Alternatively, you can try to replace the suede trim with Alcantara (which is fake suede but costs 2-3 more than the real stuff )rek:
On the topic of interiors, how does one properly clean the suede bits of leather/suede seats?
I use a leather conditioner on the leathery bits, but am paranoid of messing up the suede ..
(come to think of it, all the interior needs a big cleaning )
Autoglym make some pretty good stuff (actually makes the Macguiars look cheap). I use Autoglym Vinyl and Rubber Care for my interior and any exterior rubber bits. Good luck with finding it though!
