Hi Roger,
I've moved this over to a separate thread. I'm wondering about removal, or at least blending, of the primary ring stain on the attached chair. Unfortunately I do not know the source of the stain but given that there are splatters also on the seat back I have to assume a drink was knocked over. Hard to tell what it is though. Also, regarding the wooden frame, the leather can easily be removed from the frame on this chair for proper cleaning. Attached are images below.
Kind regards.
