Alcohol kills some things, but not everything. The same is true of bleach and hydrogen peroxide, and probably every other kind of disinfectant that exists.
No matter what kind of wipe you use, if you wipe the cart, wipe the handle bar thoroughly and then fold the wipe to capture the dirt inside or use a new wipe if you want to wipe again. Your goal is to remove visible dirt, since dirt traps a lot of microorganisms.
The best thing I can tell you is to wash your hands frequently with warm water and soap, and to try to be aware of when and how you touch your face. People touch their faces quite often. You probably don’t want to rub your eye just after you’ve touched a surface that other people touch all day long—like an escalator handrail. Wash for 15 seconds or so, making sure to lather up thoroughly and clean under the nails, then either use the back of your hand to turn off the faucet or dry your hands with a paper towel and use the towel to turn off the faucet.
Those little hand sanitizers are okay in a pinch, but you should not use them more than once or twice before you wash your hands again.
Thanks, FRiend. I will follow your instructions.
Fortunately, my mother raised her 9 kids to be careful about germs. First thing I do when I walk into the house is wash my hands. And in a public restroom my elbow probably picks up a lot of germs from the faucets and light switches.
