Black perforated leater from b5 - looking after

[ds1984]

Hi all. As probably some of u know recently I got some leather seats from b5


and now....
-Well because they come from b5 they are at least 12 years old

-they still look reasonably good but dont think they ever were treated with right cleaners and conditioners

So....
I would like to ask you guys what would u recommend to restore them and keep them protected...

Photos and videos and links kindly welcome..

And Thanks in advance
