I'm no expert in this, but I would far sooner use UV, gas or irradiation
than microwaving, both in terms of not wrecking the plastic and
actually sterilizing them. I would think any hospital would have
the equipment for this.
Are you absolutely sure it is the plates rather than your medium,
cells, water in your incubator, etc? I would think that sterile-
wrapped culture plates should be sterile much longer than a year?
Good luck!
