I recently acquired some Venetian cream and was introducing the product to my care routine for my shoes. I had used it with great effect on my Wolverine 1K's and, upon hearing of it's benefit for cordovan, decided to give it a try on my Alden loafers. As a quick note, I maintain a number of AE's, some Aldens, a C&J, and have had no issue using my Reno and wax on calf, so I'm not new to shoe care by any stretch. Having said that, I've erred significantly at some point and one of the loafers has acquired far too much cream and has developed a dark, matte patch on the toe and it isn't coming off for anything. I tried hitting it with Reno to try and maybe remove it that way, no luck. I tried water and a microfiber towel, no luck. I did some searching here for any help and online, and I was unable to find any solution. It is clearly a buildup of too much cream, and a light raking of my fingernail across will even chip some of it up. But even then it isn't removable. Do any of the shoe magicians on SF have any advice on how to get rid of this excess buildup and get back to fresh cordovan? Any help would be greatly appreciated. Below is a pic of the shoes; the left shoe is fine, the right shoe clearly displays a near-black, matte appearance on the toe which is in stark contrast to the natural, pleasing appearance of the left shoe. It was clearly my error somewhere along the way, because both shoe were treated the same. I believe I simply used far too much cream by accident and this is the result. Thanks again!
