Sorry if this is not the correct forum, just need some help. Getting into leather working a bit, but struggling with a vintage leather couch I have.
One of the cushions has a cloudy/matte appearance with a tacky feel to it. (bottom of attached photo). The other two seem to look more like they should (top of photo)
I've tried everything from wax cleaners/conditioners to non wax cleaners/conditioners to dish soap and even diluted vinegar. Nothing helps at all.
Is this leather just too far gone? Any suggestions? Thanks
