How effective is hand sanitizer vs hand washing?
Hand Sanitizer and Wipes. Soap and water remove certain germs that hand sanitizers don't kill, including germs that cause diarrhea such as norovirus, Cryptosporidium, and Clostridioides difficile. Soap and water also remove harmful chemicals like pesticides and heavy metals.
Right now, the CDC recommendation is to wash hands whenever possible. Hand sanitizer is more precise at killing bacteria and most viruses, but hand washing can effectively remove all dirt, microbes and chemicals on the hands.
Hand sanitizers don't eliminate everything
Soap and water are far more effective at removing such common illness-causing germs as cryptosporidium, norovirus and Clostridium difficile. Soap also washes away bacteria as well as other viruses that are even tougher than coronaviruses.
Alcohol-based hand sanitizers can quickly reduce the number of microbes on hands in some situations, but sanitizers do not eliminate all types of germs. Why? Soap and water are more effective than hand sanitizers at removing certain kinds of germs, like Cryptosporidium, norovirus, and Clostridium difficile1-5.
Unless hands are visibly soiled, an alcohol-based hand rub is preferred over soap and water in most clinical situations due to evidence of better compliance compared to soap and water. Hand rubs are generally less irritating to hands and, in the absence of a sink, are an effective method of cleaning hands.
Reasons to choose wet wipes over hand sanitiser
Consider using wet wipes over hand sanitisers for the following reasons. Disinfecting hand wipes have longer-lasting effects of preventing bacteria spread than the effects of using hand sanitisers. Hand sanitisers do not 100% kill germs and bacteria.
Some people have advocated that you should wash your hands after every four or five uses of alcohol-based hand rub. But, there is no reason to do this. If your hands feel 'grubby' or are visibly dirty, you should wash them with soap and water.
Cleaning alone removes most harmful viruses or bacteria from surfaces. Surfaces should be cleaned before they are sanitized or disinfected because impurities like dirt may make it harder for chemicals to get to and kill germs. Sanitizing reduces the remaining germs on surfaces after cleaning.
There's a big difference between cleaning and sanitizing. Cleaning removes food and other types of soil from a surface such as a countertop or plate. Sanitizing reduces the number of pathogens on the clean surface to safe levels. To be effective, cleaning and sanitizing must be a 5-step process.
This occurs due to the isopropyl, ethanol and n-propanol alcohols found in most hand sanitizers. These alcohols can drastically dry skin tissue and deplete our skin of oil as well as acid mantle, which triggers cell dehydration and increases the likelihood of developing contact dermatitis.

While the relative effectiveness of alcohol and bleach on bacteria and viruses does not vary greatly, it is important not to mix the two agents during cleaning.
Overall, sterilization is the most advanced form of decontamination, but disinfecting and sterilizing both kill more germs than sanitizing.
If you both clean and disinfect a surface or object, you can further lower the risk of spreading infection. There are products that clean and disinfect at the same time.
Food contact surfaces in your establishment must be cleaned and sanitized. This can be done either by heating an object to a high enough temperature to kill harmful micro-organisms or it can be treated with a chemical sanitizing compound.
The major types of sanitizers are heat, radiation, and chemicals. Chemicals are more practical than heat and radiation for food production facilities.
Bleach is a strong and effective disinfectant – its active ingredient sodium hypochlorite is effective in killing bacteria, fungi and viruses, including influenza virus – but it is easily inactivated by organic material.
Skin was exposed to hand sanitizers, and also to vodka, under varying conditions. Alcohol was transiently found to be absorbed but only by inhalation and not via the skin. It was concluded that a disulfiram–ethanol reaction is highly unlikely to be caused by skin applications alone.
Tips to avoid over washing and irritating your hands:
Use moisturizing liquid soap with a creamy consistency and ingredients like glycerin and lanolin.

A quarter (25%) say they wash with soap most of the time after a trip to the bathroom at home, while 10% do this some of the time and 4 percent rarely do. The generation that's least likely to use deodorant might also be the least likely to consistently wash their hands.
However, if hand sanitizer remains in the container, EPA recommends that households not put the hand sanitizer in the regular household trash. Instead, EPA recommends that household hand sanitizer waste be brought to a household hazardous waste drop-off location or event for proper management.

Joel Schlessinger recommends cleansing skin with your hands over a shower loofah or washcloth. The cons: There's one thing hands don't do particularly well, and that's exfoliation. Because hands are not considered optimal for exfoliation, they can leave behind dirt, oil and dead skin cells.
What is the most sanitary way to dry hands at home?
It is likely that paper towels work better because they physically remove bacteria from the hands, whereas hot air dryers and jet air dryers cannot. In many instances, however, rubbing hands with hot air dryers to hasten drying would only lead to greater bacterial numbers and airborne dissemination.
Although some experts still debate this topic, drying your hands with a clean, single-use hand towel may be the safer choice to reduce the risk of spreading germs, according to Okeke-Igbokwe.
Soap and water is always best – wherever possible, do try to use soap and water: it doesn't dry the skin as much as sanitiser. Always keep some moisturiser with you – sanitisers are particularly bad for drying out the skin, but even frequent washing with soap and water can be detrimental over time.

However, there are a number of reasons why hand sanitizers should be used only when soap and water is not readily available and should not be used as a substitute for proper hand washing, particularly by Food Handlers.
What is the disadvantage of sanitizer?
Skin irritation – Excessive use of hand sanitizers, which contain chemicals such as alcohol, chlorhexidine, chloroxylenol, and triclosan, can cause irritation as it strips away the skin's natural oils. When the skin's natural moisture barrier gets disrupted, it becomes more susceptible to bacteria.
In a study conducted to investigate the effect of skin damage due to repeated washing, it has been found that frequent handwashing over a long period of time can cause long-term changes to the skin, resulting in skin conditions such as chronic skin damage, irritant contact dermatitis and eczema.
Several physical and chemical factors also influence disinfectant procedures: temperature, pH, relative humidity, and water hardness. For example, the activity of most disinfectants increases as the temperature increases, but some exceptions exist.
Sanitizers containing an alcohol concentration between 60–85% are suggested to kill 99.99% of microorganisms on hands.
Several factors influence the effectiveness of chemical sanitizers. The most critical include concentration, temperature, contact time, water hardness, and pH.
