Clean tags and other non-audio chunks from .wav. How to?

So even after using Mp3tag and fb2k to remove tags, and foo_sanitizer, running flac still returns:
WARNING: skipping unknown chunk 'JUNK' (use --keep-foreign-metadata to keep)

How to strip the .wav file for all the junk with or without capitals?

For foobar2000, use the file converter and write to a new .wav file.
