Copper is of course, chemically incompatible with most disinfectants and cleaners and will corrode. Which is one reason it stopped being used when ammonia/etc became super common. They are less common now in straight form (even Windex is no longer mainly ammonia unless you use the original formula version)
So solid copper/brass i can get behind because it probably doesn't affect lifetime meaningfully, but I am very curious how the coating in the article withstands splashes of ammonia or peroxides or other things used to clean the floors or windows.
- FieryTransition 2y agoI was wondering about this too, it's not viable to have a coating which necessitates changing equipment periodically. It will add logistical problems and waste. I think you are right in that using solid metals instead, makes more sense, given antibacterial properties have been known to exist for these for a while. The question is if all types of pathogens can be removed without damaging the equipment, or if material research could create an alloy which just like stainless steel, could make the metal form an oxidation layer which would protect it in case of contact with corrosive liquids.
