I hd a Hartman Briefcase that got a bit moldy from a trip overseas into a really humid environment. I started the deep clean process by misting the bag with alcohol severl times in a week. I also kept it in a dry hot room. At the end I hit it with a chlorine spray. Chlorine is the best oxidizing agent known. After praying and drying I polished the bg with a leather stain .
Back to the hat room for about a week and thn check it out.
The mold "smell" was gone an I still have the bag in use today. Although its function is different, Today it nestles a s mall drone and a
a go pro set with charger and cables. Its a deep bag so It cn carry a lot
