Thanks, Doccan you recommend a suede cleaner that would be safe to use on orange doblis?
And which brush do you recommend to use in general for doblis?
If it doesn't help, is there a way it would be safe to dye suede around corners?
Your edges might be oil or grease or wear which would all require different approaches. You wont want to try dying the edges with a light color if they are darker that will be a dang mess and you'll end up very unhappy ... I might say seeing how you maybe getting in over your head to ask Hermes if this is anything they can fix for you. I suspect they will say no. But its worth asking.
You can clean the suede with Luxury Again Cleansing Wipes and a suede brush or Other suede cleaners ( Fiebings, Argus, Meltonian) and a suede brush
If you are unhappy with the color you can go darker over all with a suede dye by Argus but you will lose something special if you chose that route, the lovely hand feel will be altered and it will no longer be an original... Can you live with this? Would you like to try the tape trick and see if you get some improvement? Take some clear wide packing tape put it on the edges and the peel it off, it can lift off some dirt and bring up the nap in many cases. How about trying that? then see if that's enough... you can try buffing with some suede sanding block or pumice stone like a professional would use but I would take great care as you would need some skills and experience not to get in to deep trouble and ruin your bag with novice vigor.
All the best, doc
