Is Killing 99.9% of Bacteria and Germs False Advertising? The short answer is yes, because it is made as a blanket statement. The advertiser intentionally drops the amount of time (dynamic delay) needed to achieve the objective of killing 99.9%, for example they never say “instantly kills 99.9%” or “kills 99.9% in 10 minutes”, etc. For viruses and some germs, even the use of the word “kill” is misleading, because they do not die, they encapsulate themselves until better conditions exist again, then they are back to regular life. It takes 10 to 15 minutes for these chemicals to work, but then after you touch a door handle, you have to clean it again. This is why at hospitals, you have a full-time employee doing just that. There’s a better way, use copper-based door handles, it is naturally anti-bacterial due to its molecular structure. This is why, with trial-and-error and many casualties, people settled hundreds of years ago on using pots made from copper. Now, copper poisoning is a totally different discussion.
