Your tack is a major investment, and if you’ve left it to sit a bit too long, chances are you’ll return to find it covered in a green coating of mildew. This mildew’s not only inconvenient – left untended, it will continue to grow at a surprisingly fast pace until it coats your entire saddle or bridle. Thankfully, with proper care you can rid your tack of mildew, and can even take steps to prevent it from ever becoming a problem.
