Hello everyone, there are staples holding some vapor barrier inside a wooden cage and all of a sudden the staples have begun rusting and had a bit of brownish water condensing on them. I am very concerned! I have read rust isn't toxic but am not sure. I went in the cage and wiped away the dirty looking water and scrubbed away as much rust as I could muster. Have it venting now so it's not so humid in there.

Advice, tips, hints to resolve this? Thanks
