You are generalizing OP, PPE is used by so many different groups it's different in every situation.
Now for example care services are terrifyingly short staffed , I mean insanely so. I know managers and carers who are pulling double and triple shifts , sleeping in break rooms, so exactly who do you think would wash these? Even if they currently existed and the processes to clean them at high temo.
Washing PPE in the way you describe would take far more man hours than you have any idea of (its patently patently clear you do not work in any form of industry with direct frontline with Covid at the moment)
Care services are desperate for PPE (I do mean desperate I helped a contact out on froday who had to find 1000 pieces just to get through next week as her service didn't have enough to make it through the weekend ) if there was a safe way currently to reuse , I guarantee you they would.
There isn't currently a safe option that isn't single use. As other PP have said this is the last thing on most of their minds right now.
I do think you've been jumped on but I sort of understand peoples frustration. It feels like a lazy musing from someone sitting in a lauded safe position. People ar just trying to survive right now , they dont need to be worried about the environment in that way. I suspect you meant well but haven't recognised other peoples situations.
