Does Reno accomplish the same thing, i.e., blending previously applied layers of wax and/or will the reno help to ensure that you don't build up too many layers of wax? or, is a solvent like alcohol the only way to remove old layers of wax.
Answer (by @nutcracker , owner of The Oak Room, a great shoe store in Taiwan): I suggest Saphir Renomat instead, though I believe it does contains some alcohol. It should do a good job removing built up wax. granted you use it gently in several layers if needed. If you're rough, these stuffs can strip the leather down to bare skin (natural color) if rubbed too hard (speaking from experience).
