Reanalyse:I have a UV sterilisation box (originally meant for cellphones)
Would this be good for sterilising KN95 masks after use (bit light pegging the masks out in sunlight for a few hours I imagine.
You can also sterilise masks up to 20 times in the microwave. 60 mil of water in a glass and put the mask over and secure with rubber band. Microwave on high for 3 min. Apparently the metal bit won’t spark but I can’t vouch for that. Kills the corona virus.
