Restoring leather - chair back
Hello,
I would like to restore the leather of some cantilever chairs to give them a new lease of life. I collected these chairs with many grease stains, liquid stains and so on, which have been there for years.
Ideally I would get back a colour similar to the original, otherwise a darker shade to hide the stains would also be possible. The leather is thick, a little stiff, but it is not cracking too much.
What process should I follow to get a good result?
Thank you very much and have a lovely day,
Julie :)
