Filson 48 Hour Tin Moldy Odor any way to clean or recommendations for reproofing in San Francisco?

My 48 hour tin cloth bag has a strong moldy smell I see online.

I’ve tried febreeze, dryer sheets, leaving it in the sun. Still there and prevalent.

Another recommendations to get rid of if. It’s annoying enough I might have to get rid of the bag itself. Thank you.
