Change the sanitizer often to make sure it stays clean and fresh
Every time it gets soiled or wet !
Sanitizer solution should be changed every 2-4 hours, or more frequently if it becomes visibly dirty or contaminated. It's essential to follow proper hygiene protocols to maintain a clean and safe environment.
The best way to try and not catch a cold is just to wash your hands often. If you wash your hair don't leave it wet, get it as dry as you can as fast as you can. Do not go outside with your hair wet. Carey a hand sanitizer around with you. And avoid being around people that you know are sick.
The evaporation of hand sanitizer is an endothermic reaction. This phase change, from liquid to vapor requires heat and the alcohol takes the heat from your hand to evaporate. Therefore you feel cooler. It is a physical change, not a chemical change.
Hand sanitizer is generally more effective at killing germs on hands than on a doorknob. This is because hand sanitizers are designed to work on organic materials like skin, where they can penetrate and eliminate pathogens. On surfaces like doorknobs, the effectiveness can vary based on the type of germs, the surface material, and how long the sanitizer remains wet. For optimal disinfection of surfaces, using disinfectant wipes or sprays is often recommended.
A wet sanitizer should contain a disinfecting solution with active ingredients like alcohol, bleach, or hydrogen peroxide to effectively kill germs and viruses. It should also have water or other solvents to ensure proper coverage and drying on surfaces. Check the label for specific instructions on usage and contact time for disinfection.

Technically, since it's a hand sanitizer and sanitizer means "to make sanitary, as by cleaning or disinfecting" then obviously it's the dirt get cleaned and not the sanitizer get dirty.
