If it has to have the word "disinfectant" in bright bold letters on the package for a person to understand it's a disinfectant, that person is an idiot, and perhaps having them drink bleach would benefit the gene pool.
-I usually use alcohol to disinfect cuts and scrapes.
-Vinegar is a weak natural disinfectant.
Hydrogen peroxide is still way different than bleach. I hope you wouldn't use bleach to clean an open wound.
"another thing... who the f**k in the world uses mouthwash?"
Um, what? Most people in the U.S. use mouthwash, with Listerine being the most common brand. (I don't know if it took a hold outside the U.S. Listerine used an ad campaign to convince people that bad breath was a common thing and you needed their product, which is an antiseptic/disinfectant, to treat it) even if you choose not to use it, I find it odd that you would not at least be familiar with the concept.
