So what kills more germs and cleans your hands the best, washing your hands with soap or using hand sanitizer? Hand sanitizer says it kills 99.99% and to me that seems to be pretty good so does washing your hands do better.
The Center for Disease Control says that when you get the choice between hand sanitizer and washing your hands you should wash them. Washing your hands with soap and water is the best way to clean your hands and kill germs. Alcohol based sanitizers do reduce germs but do not kill all kinds and the sanitizer has to be at least 60% alcohol. Also hand sanitizers are not good when it comes to hands with grease or visible dirt. Hand sanitizers can also cause germs to develop resistance to the sanitizing agent which can make strong germs and virus’s that our medicine can’t protect us from.
Many studies show that hand sanitizers work well in clinical settings like hospitals, where hands come into contact with germs but generally are not heavily soiled or greasy. This goes to show that there is a time and a place to use hand sanitizers but when you can you should wash with soap and water since this is the only sure wash to completely kill all the germs and clean your hands.

I have always wondered how efficient hand sanitizer is, especially when the main ingredient is water. It is interesting that it is less effective on greasy or soiled hands. You could include why this is. If it is 99.9% effective, why does it depend on the substance that is on your hands. Alcohol has to be 60% in the sanitizer to actually do its job, but what are the other active ingredients? You could expand and compare the percentage of efficiency hand-washing offers to that of hand sanitizer. What experiments have been done to prove this? Your blog would be more effective if you explained experimental studies that were done on your topic.
