I have both Mongolian and Siberian grains in glass vials which I had cleaned out over three years ago and I have never experienced mould at all. The grains even now are perfectly fine and hold a wonderful animalia scent.How about replacing/refreshing the silica gel bags every day until dry?
Or rinsing the musk grains in alcohol then filtering them out and drying tham.
The alcohol should kill any mold or bacteria and wash away the scent, and make drying faster.
By rinsing I mean a quick rinse, not a soak/tincture.
