You are absolutely correct, so saphir renovateur actually strips the finish of a shoe? I was under impression it helped the shoe etc after reading on hanger project site. Just surprised he would recommend that on a new shoe. Specially if it messes up the new finish etc dam lesson learned will not do that again.
I'm by far no expert and I can certainly be wrong for all I know. But it just seems to me that it doesn't make much sense especially with a new shoe anyway. I wouldn't say it messes up the finish on everything, but it certainly removes more than any other conditioner\cleaner I've ever used.
