Incidently all door handles, door push plates, lift buttons, road crossing buttons and surrounding button facias should be made from copper, brass, cupronickel or chromium as viruses and bacteria would be killed within an hour without the need for being disinfected.
Nickel could also be used but 17% of women and 3% of men (average 10%) are hypersensitive to this metal so why it is used as the outer coating of 5p and 10p coins since 2012 is beyond me.
Anyway a micro texture can now be etched into these metal surfaces with a laser that can that can decrease kill time to a couple of minutes.

This one last 4h on Copper but agreed its generally far more hostile to viruses than other surfaces.
And I agree about Nickle. had a belt with a Nickle buckle and it messed up my skin big time!
