I noticed some mold on a couple of coon hides, do I just wipe it off, or do I need to put something on them? I only have 1 hide per nail … so they are getting plenty of air

Wipe it down with vinegar.

Agreed.

Or rub it out with a little powdered borax.

A fan on the hides while they dry will help prevent mold as well.

I'd rub sodium benzoate on it because it’s handy in the shed.

Wet down a rag with wd-40 and wipe down the leather. It works like a charm.

Don’t thank me. Thank the late Greg Schroeder.

I use Hydrogen Peroxide on any leather products that show mold. Works great and never returns.

Interesting. There are more and more uses for that stuff.
