Had a lot of rainy days in a row the last couple of weeks so I haven't been able to hang my leather jacket out in the sun to dry completely and what I have noticed is that mould is beginning to grow out of the stitches. How do I stop this from happening, now and later on when it is damp again. I have sprayed the jacket with some disinfectant spray and hung out in some sun yesterday but I have heard somewhere to rub wax (Like surfboard) into the stitching, does this sound right??
