I'd tend to agree with Bill here, wrt the contact time with the nylon.
I'd actually expect a lot more in terms of extractables/plasticisers
from anyone using PVC in any way or urethane racking tubes, food grade
or not. No proof for that thought, just experience with plastics. The
saran-wrap solution is probably good, even if you used packaging wrap
instead of the standard leftovers-wrap at the grocery store.
