What Causes A Sanitizer To Not Work Well

What Causes a Sanitizer to Not Work Well

Sanitizers are an essential tool in maintaining hygiene and preventing the spread of germs, but they are not always effective. Several factors can contribute to a sanitizer’s inability to work well, including:

Insufficient Alcohol Concentration

One of the most common reasons a sanitizer may not work effectively is an insufficient alcohol concentration. The CDC recommends using hand sanitizers with at least 60% alcohol content to kill germs effectively. Sanitizers with lower alcohol concentrations or non-alcohol-based sanitizers may not work as well, as they merely reduce the growth of germs rather than kill them outright.

Improper Application

Proper application is crucial for a sanitizer to work effectively. When using hand sanitizer, it is important to apply the product to the palm of one hand and rub it all over the surfaces of both hands until they are dry. Failing to cover all surfaces of the hands can leave some areas unprotected and allow germs to survive.

Heavily Soiled or Greasy Hands

Hand sanitizers may not work well when hands are heavily soiled or greasy, such as after handling food, playing sports, working in the garden, or going camping or fishing. In such cases, handwashing with soap and water is recommended.

Certain Types of Germs

Some types of germs, such as Cryptosporidium, norovirus, and Clostridium difficile, are more resistant to sanitizers and may not be eliminated effectively. Soap and water are more effective at removing these types of germs.

Improper Storage and Handling

Improper storage and handling of sanitizers can also affect their effectiveness. Sanitizers should be stored in a cool, dry place and kept out of direct sunlight. Exposure to high temperatures or humidity can cause the alcohol content to evaporate, reducing the sanitizer’s potency.

Contamination

Sanitizers can become contaminated if they are stored in unclean containers or if they come into contact with dirty hands or surfaces. Contamination can introduce germs and reduce the sanitizer’s effectiveness.

Expired or Damaged Sanitizers

Using expired or damaged sanitizers can also lead to ineffective results. Sanitizers have a limited shelf life, and using them after their expiration date may result in reduced alcohol content and decreased effectiveness. Additionally, using sanitizers with damaged packaging or containers can allow contaminants to enter and reduce their potency.

Homemade Sanitizers

While homemade sanitizers may seem like a cost-effective alternative, they may not be as effective as commercially produced sanitizers. Homemade sanitizers may not contain the proper alcohol concentration or may be made with ingredients that are not approved for use in sanitizers. Using homemade sanitizers can lead to ineffective results and potentially cause skin irritation or other adverse effects.
