remove mold from leather
 

Any ideas? It's an original 03A3 sling.

Use a good leather conditioner . That should do the trick

Off the bat i would recommend exactly what the gentle above me posted.
Can we get some pics of the leather?

Yeah I'll try the conditioner. No pics. Sling is at the shop. Thanks guys

Lexol and a soft scratch pad.

Murphy's oil soap works good

Ballistol works
