For decades we have used harsh chemicals to clean in our homes, and it makes sense. If you want to kill nasty bacteria and viruses you have to use harsh chemicals, right? Actually you don't. You just have to use chemicals that will denature, or break down proteins, since all bacteria and viruses are protein based. It turns out that there are some chemicals that are non-toxic to humans, but can still denature proteins of bacteria and viruses, effectively killing them. So instead of using chemicals that can cause harm to the user, green cleaning products can be used, which still clean and sanitize without hurting the user or the environment.
