Interesting! Can you describe the procedure you used to wash them?

hmm long long time ago, we had some building work done and extended
the building upwards, of course the weather turned bad over the
weekend, with the obvious wet and gritty result, Luckily it was only a
couple of days and the floppies were still wet. So I cut the sleeves
off and rinsed under the tap iirc no agressive cleaning fluids needed.
Then dried (tissue paper) and place in between listing paper to fully
dry and keep flat. Then a clean floppy was cut open to use the sleeve
and the data recovered. Also making sure the floppy heads were clean
during the operation. Took about a day iirc. This was back in the days
when the Commodore PET was THE computer at work.
