I have put a thin layer of pure vaseline onto a couple of my GL-831 straps, optically they look much better than before but I am not really sure if this is good for the rubber though!
I won't take the risk of boiling them because I am afraid they may dissolved as they are quite old...

there is a member here that posted this about pure vaseline so I gave it a try, I washed it and removed the dirt and applied a very thin layer on both sides, it worked great, I will take some photos tomorrow.
I guess next time olive oil will be my choice, natural product so less harm on the original rubber.

you did a good job there, olive oil does the trick!

interesting, this is how it looks 2 weeks after a very thin layer of pure vaseline applied.
