Go to the liquor store and buy a bottle of 100 proof Vodka. It will work!
Yup. Look at the active ingredient in Purell or generic had sanitizers. It is isopropanyl alcohol (rubbing alcohol) which is not to be taken internally. However, high proof ethanol alcohol (in booze) is just as effective.
Easier, buy some quarts of rubbing alcohol and mix with aloe vera or other hand lotion since the alcohol will dry out your hands if used alone.
We do the above not because of Covid-19, but to avoid cold and flu season. MOST IMPORTANTLY: Before you touch the first doorknob when entering the house, thoroughly wet down your hands and saturate the knob before your choice of product drys. AS IMPORTANTLY: Never touch your face when out and about until you can clean you hands with any alcohol. If you have an itch, use the back of your hand.
