How to remove mildew and mold from a leather saddle?

I personally wouldn't use bleach on leather. I have had to clean mold and mildew off of my saddle before. Just use some water on a cloth to get the excess dirt, etc. off. Then just use some saddle soap to finish.That should work just fine, it has for me.If the weedkiller is stubborn you can use some dishwashing soap then a clean wet cloth.Good luck!
