I've been hoping I could find a relatively easy way to sterilise,
clean and reuse my coronavirus protection face masks, without the need
of powerful disinfectants and alcohol (which are of course also in
short supply). Then I came across this method online where a guy
reckons it's possible to do all this with just soap, hot water and a
toothbrush (it's almost as easy as washing your hands).
The guy plausibly (I thought) explains his method in a video:

Could I please ask the 'experts' here in this newsgroup if they think
this is a good idea... or not?
I can provide a mask, please reply if necessary.
