How Should Food Handlers Dry Their Hands After Washing?

Drying your hands properly after washing is a critical step in food safety, yet it is often rushed or done incorrectly. The best method is to use single-use paper towels or an air dryer, and to dry your hands thoroughly until they are completely dry. Damp hands transfer bacteria much more easily than dry hands, so this step is not just about comfort—it directly affects how safely you handle food.

Why Is Drying Hands So Important for Food Handlers?

Washing your hands with soap and water removes dirt and most germs. But the rinsing process can leave your skin wet, and wet skin is a perfect environment for bacteria to survive and multiply.

Research consistently shows that bacteria transfer more readily from wet skin than from dry skin. When you touch a cutting board, a utensil, or a piece of food with damp hands, you are more likely to leave behind any remaining germs. Thorough drying removes that moisture and reduces the risk of cross-contamination.

Drying also helps protect your skin. Constant moisture can break down the skin barrier, leading to irritation and cracks. Damaged skin harbors more bacteria and is harder to clean effectively the next time you wash.

What Is the Best Way to Dry Hands in a Food Service Setting?

Single-use paper towels are widely considered the gold standard in commercial kitchens. They are effective at removing moisture and bacteria through friction, and they do not contaminate your hands again after use.

Here is the proper technique for using paper towels:

• Take one or two paper towels from the dispenser.
• Rub your hands together thoroughly, covering all surfaces including the backs of your hands, between fingers, and around the wrists.
• Continue rubbing until your hands are completely dry.
• Use the same paper towel to turn off the faucet and open the restroom door, if applicable.
• Dispose of the paper towel in a hands-free trash can.

Air dryers are also acceptable in many health department jurisdictions. Modern high-speed jet air dryers are effective at drying hands quickly. Older warm-air dryers take longer and may leave hands slightly damp if you do not wait the full cycle. If you use an air dryer, keep your hands in the airflow until they are completely dry—do not walk away early and wipe your hands on your apron or clothing.

What Methods Should Food Handlers Avoid?

Some drying methods are common but not acceptable in a professional food service setting.

Cloth towels shared by multiple people are not allowed in commercial kitchens. A shared cloth towel becomes contaminated after the first use. Even a clean-looking cloth towel can harbor bacteria that transfer directly to your freshly washed hands.

Drying your hands on your apron, your uniform, or any other part of your clothing is also unacceptable. Your clothing touches surfaces throughout your shift and is not clean enough for this purpose.

Letting your hands air dry naturally without any assistance is inefficient. This method leaves your skin damp for too long, increasing the risk of bacterial transfer. It is not a recommended practice for food handlers.

Do Paper Towels or Air Dryers Work Better?

Studies comparing paper towels and air dryers have produced mixed results. Some research suggests paper towels remove more bacteria through the physical friction of rubbing. Other studies indicate that modern jet air dryers are just as effective when used correctly.

What matters most is that your hands end up completely dry. Both methods can achieve this if you use them properly. The choice often comes down to what your facility provides and what your local health code requires.

One consideration is the restroom environment itself. Some studies have found that air dryers can disperse bacteria into the surrounding air, potentially contaminating nearby surfaces. The clinical significance of this finding is still debated. Paper towels avoid this issue entirely because they capture and remove bacteria rather than blowing them around.

For this reason, many food safety experts prefer paper towels in kitchens and food preparation areas. If your facility uses air dryers, they should be well-maintained and positioned away from food contact surfaces.

How Long Should You Dry Your Hands?

There is no universal time requirement for hand drying. The standard is simple: dry until your hands are completely dry. This usually takes 20 to 30 seconds with a paper towel if you are rubbing thoroughly. With a high-speed jet air dryer, the cycle is typically about 10 to 15 seconds. With a warm-air dryer, it may take 30 to 45 seconds or longer.

Do not rush this step. If your hands still feel damp, they are not ready. Continue drying until there is no visible moisture on your skin.

After drying, do not touch your hair, face, or any surface that could recontaminate your hands before you return to food preparation. If you touch anything unclean, you must wash and dry your hands again.

What Do Health Codes Require for Hand Drying?

Most local and state food safety codes follow the same general principles. Food establishments must provide a method of hand drying that does not recontaminate hands. In practice, this means single-use paper towels or approved air dryers.

Health inspectors check for several things when they evaluate handwashing stations:

• Adequate supply of paper towels or a functioning air dryer
• Hands-free operation of the faucet and paper towel dispenser where possible
• Proper placement of the handwashing station near food prep areas
• Visible signage reminding employees to wash and dry their hands

If a facility fails to provide proper hand drying supplies, it can receive a violation during inspection. Repeated violations can lead to fines or even closure in severe cases.

Food handlers should know their facility’s specific policy and follow it every time. Consistency matters more than any single technique.

Does Hand Dryer Type Affect Food Safety?

The type of dryer can make a practical difference in how likely employees are to dry their hands completely. If a warm-air dryer takes 45 seconds to work, busy staff may not wait that long. They might walk away with damp hands, defeating the purpose of washing.

High-speed jet dryers are faster and may encourage better compliance. But they are also louder, which some employees find unpleasant in a busy kitchen environment.

Paper towels offer the advantage of speed and reliability. You control the process, and there is no waiting for a machine cycle to finish. The friction of rubbing with a paper towel also provides a mechanical cleaning effect that air alone cannot match.

From a pure food safety standpoint, the best method is the one that your staff will actually use correctly every time. If your team consistently uses paper towels properly, that is a strong choice. If they prefer the speed of a jet dryer and use it correctly, that can also work.

What About Hand Sanitizer After Drying?

Hand sanitizer is not a substitute for proper handwashing and drying. In food service, sanitizer can be used as an additional step in some situations, but it cannot replace the wash-and-dry process.

Sanitizer is most effective on clean, dry hands. If you apply sanitizer to damp hands, it becomes diluted and less effective. This is another reason thorough drying matters.

Some facilities require employees to apply a food-safe sanitizer after washing and drying as an extra precaution. This is acceptable but not required by most health codes. The wash-and-dry process itself is sufficient when done correctly.

Drying your hands is not a formality. It is a measurable step in preventing foodborne illness. Every time you wash your hands, finish the job completely. Use the supplies provided. Take the extra 20 seconds. Your customers depend on it.
