has anyone sterilized these in a pressure cooker? if so, how do they hold up?

This petri dish is not suitable in the pressure cooker and cannot use for hot water.

We were able to do so multiple times by cleaning and rinsing with dishwashing soap and water, then 20 minute soak in household bleach 10:1 dilution, then rinse in tap water, then dip in 91% isopropyl alcohol and leave on rack face down to dry. Nothing seemed to grow in autoclaved agar in 24 hours.

They are not marked sterile, but after 20 plates of mushroom clones I've have one plate with contam and that likely came off the original mushroom.
