Thanks for sharing. I used to have a wool sweater cardigan and I tried all these methods plus some others and nothing worked. It always smelled like musty pee. This weekend when I have time I'm going to come up with some genius plan and do a bunch of experiments. Otherwise I can just wear it and be smelly and its okay if people avoid me because the coat looks so good.
I went to Zara today and an SA told me that the (smelly) coat with the quilted leather sleeves has been returned to the warehouse as they were all recalled. I'd noticed it was no longer on the website and I couldn't find it at all when I did a search. The SA said she didn't know why it has been recalled but I'm assuming it has something to do with the smell. Hopefully, they will redesign this coat and use a material that isn't so offensive to the nose!
