I stored my english bridle in a storage unit for about 4 months. Before that I soaked in it oil for about a week. So when I pulled it out today its covered in sticky white mold that isnt happily coming off. I feel the fact that I heavily oiled it before it was stored didnt help. The leather is soft and feels like it was recently oiled. Which is making it tougher for the mold to effectively come off. Any tips?
