Furthermore, can you sterilize with alcohol?

Alcohol rub sanitizers kill most bacteria, and fungi, and stop some viruses.
Besides, why is 70 Alcohol a better disinfectant than 95 alcohol?
70% percent of alcohol is ideal to a stronger solution. Pure alcohol coagulates protein in contact. If 70 percent of alcohol is poured to a single celled organism, the diluted alcohol also coagulates the protein, but at a slower rate, so that it penetrates all the way through the cell before coagulation can block it.
