I was recently fortunate enough to get my hands on a ever so slightly used Streich-Riemen loom strop with one side pasted with 0.5 crox.

The first thing I noticed when I received it was that the crox was absolutely pasted on, almost matted, even with chunks remaining. No big deal as I can obviously wipe the excess off and carry on with life, but it also looks like it was put back in the box it comes in with the wax paper reversed, so the side of the wax paper that touched the pasted side then touched the clean leather side, such that there appears to be some contamination, as evident by a very slight discolouration (most visible in the second picture, about 1/4 of the way from the end). What I'm wondering is this:

1) how big of a deal is this? Am I over-thinking something that just isn't a major issue, given that the cross contamination?
2) if it is an issue, what's the best approach here? I'm been reading the forums all day and saddle soap comes up often; so too does a light high grit sanding followed by reconditioning the leather.

If anyone has run into this problem before or has any advice I would certainly value your experience.

Kind regards,
Paul
