I think it depends how smelly/musty the bag is. I tried almost everything for my first Noe but nothing worked. I couldn’t even figure out what the smell was- it was just horrible. I tried dryer sheets, Febreze spray, wipes, Damp Rid - note to self: NEVER use that again, coffee grounds, newspaper, fresh air, sunlight, deodorizer spray, deodorizer balls, perfume, Lysol, lemon water scrub, scrubbing with water and dish liquid....that smell always came back!
Btw, the Damp Rid expanded into a huge chemical mess on the bottom of the bag. It really soaked up moisture. [emoji51]
I ended up selling the bag with full disclosure.
