Antibacterial Soap vs. Regular Soap vs. Hand Sanitizer: Which Is Best for Avoiding Germs?
Updated: Aug 11
Authored by La Jolla Vitality Co.
We wash our hands dozens of times a year, especially during cold and flu season, after using the bathroom, before eating, and whenever we're around someone who is sick.
But with so many products available - regular hand soap, antibacterial soap, foaming soap, antimicrobial washes, and alcohol-based hand sanitizers - which one actually provides the best protection against illness?
The answer may be surprising:
For everyday handwashing, plain soap and water are generally the best choice. Antibacterial soap has not been shown to provide additional health benefits for consumers, while alcohol-based hand sanitizer is an excellent alternative when soap and water aren't available.
In other words, you don't need an antibacterial label to get excellent protection from handwashing.
The most important factors are using the right product, washing at the right times, and using proper technique.
Why Handwashing Prevents Disease
Our hands are constantly touching things:
Door handles
Phones
Keyboards
Shopping carts
Food
Faucets
Our faces
Other people
Microorganisms can be transferred from contaminated surfaces to our hands and then into our eyes, nose, or mouth.
Hands can also become contaminated after:
Using the bathroom
Changing a diaper
Coughing or sneezing
Blowing your nose
Caring for someone who is sick
Handling raw food
Touching animals or animal waste
Handling garbage
Handwashing interrupts this chain of transmission.
The CDC describes handwashing with soap and water as one of the best ways to prevent the spread of infections, including respiratory and gastrointestinal illnesses.
So, Is Antibacterial Soap Better Than Regular Soap?
No, not for routine consumer handwashing.
This is one of the biggest misconceptions about hand hygiene.
Antibacterial soaps contain ingredients specifically intended to kill or inhibit bacteria.
Regular soap does not contain these antibacterial active ingredients.
It might therefore seem logical that antibacterial soap should be more effective.
But the science doesn't support that conclusion.
The CDC states that studies have not found an added health benefit from antibacterial soap compared with plain soap for consumers. The FDA has also determined that manufacturers did not provide sufficient evidence that certain antibacterial soap ingredients were both safe for long-term daily use and more effective than plain soap and water at preventing illness.
That's why the FDA removed several commonly used antibacterial ingredients from the consumer soap market.
The key lesson:
You don't need to kill every microorganism on your hands. You need to remove potentially harmful microorganisms effectively.
And plain soap and water are very good at doing that.
How Does Regular Soap Work If It Doesn't “Kill” Bacteria?
This is an important distinction.
Soap primarily works by loosening microorganisms, dirt, oils, and other debris from your skin so they can be rinsed away with water.
Soap molecules have properties that allow them to interact with oils and other substances on your skin.
When you rub your hands together with soap and water, you physically lift microbes and contaminants from the skin.
Rinsing then carries them down the drain.
That's why the mechanical action of washing is so important.
The CDC notes that soap is more effective than water alone because soap's surfactants help lift soil and microbes from the skin, while scrubbing further removes them.
What About Hand Sanitizer?
Hand sanitizer is different.
Alcohol-based hand sanitizers work primarily by inactivating or killing many microorganisms on the hands rather than physically washing them away.
They can be extremely useful when soap and water aren't readily available.
The CDC recommends using a hand sanitizer containing at least 60% alcohol when soap and water aren't available.
Examples of situations where sanitizer can be useful include:
Traveling
Riding public transportation
Shopping
At sporting events
At school
At work
In the car
After touching frequently handled surfaces
Think of sanitizer as a convenient backup, not necessarily a replacement for handwashing.
Soap and Water vs. Hand Sanitizer
Both can be effective, but they have different strengths.
Plain Soap + Water | Alcohol Hand Sanitizer | |
Removes dirt and oils | Excellent | Limited |
Removes many germs | Excellent | Excellent for many germs |
Works on visibly dirty hands | Yes | No—less effective |
Removes certain chemicals | Yes | No |
Convenient when traveling | Less convenient | Excellent |
Requires running water | Yes | No |
Recommended alcohol concentration | N/A | At least 60% |
The CDC specifically notes that soap and water are more effective than sanitizer at removing certain organisms, including norovirus, Cryptosporidium, and Clostridioides difficile, and can remove harmful chemicals that sanitizer cannot.
When Should You Choose Soap and Water?
Use soap and water whenever they're readily available, particularly when your hands are visibly dirty or greasy.
Important times include:
Before eating
Handwashing helps prevent microorganisms on your hands from entering your mouth with your food.
Before preparing food
This is particularly important for preventing foodborne illness.
After using the bathroom
This is one of the most important handwashing occasions because fecal microorganisms can be transferred to your hands.
After changing diapers
Young children can spread gastrointestinal infections very efficiently.
After caring for someone who is sick
Especially if you've been exposed to bodily fluids or respiratory secretions.
After coughing, sneezing, or blowing your nose
Wash your hands afterward rather than simply wiping them on clothing.
After handling animals
Animals can carry microorganisms that can cause illness in humans.
After handling garbage
Garbage can contain a variety of microorganisms and contaminants.
When Is Hand Sanitizer the Better Option?
Hand sanitizer becomes particularly useful when you can't get to a sink.
Keep a bottle:
In your purse or backpack
At your desk
In your car
In a travel bag
Near the entrance to your home
Choose an alcohol-based product containing at least 60% alcohol.
Apply enough sanitizer to cover all surfaces of your hands and rub your hands together until they are completely dry.
Don't wipe it off prematurely.
What About Using Hand Sanitizer After Washing?
You generally don't need to wash your hands with soap and water and then immediately apply sanitizer.
Doing both isn't necessarily better than properly washing your hands.
Instead, think of them as two complementary tools:
Soap and water when available.
Hand sanitizer when soap and water aren't available.
The goal is effective hand hygiene, not maximum chemical exposure.
Can Hand Sanitizer Cause Antibiotic Resistance?
Alcohol-based hand sanitizers are different from antibiotic medications.
According to the CDC, alcohol-based hand sanitizers do not contribute to antimicrobial resistance in the same way that antibiotic exposure can select for resistant bacteria.
Alcohol works by damaging microbial proteins and membranes rather than acting like an antibiotic drug.
This makes alcohol-based sanitizer a useful tool when handwashing isn't practical.
However, sanitizer shouldn't be thought of as a substitute for cleaning visibly dirty hands.
What About Antibacterial Soap and Antibiotic Resistance?
This is one reason routine antibacterial soap isn't necessary.
The CDC notes that some studies have suggested antibacterial soap use may contribute to antimicrobial resistance, while plain soap does not.
The bigger point is that if an antibacterial ingredient doesn't provide a meaningful additional benefit for everyday handwashing, there is little reason for consumers to seek it out.
Plain soap does the job.
Is “Natural” Soap Better?
Not necessarily.
A soap doesn't have to be natural, organic, fragrance-free, or expensive to clean your hands effectively.
The key question is whether you're using soap and water correctly.
That said, people with sensitive skin may prefer fragrance-free products to reduce irritation.
Skin health matters because excessively dry, cracked skin can become uncomfortable and compromise the skin barrier.
If frequent handwashing causes significant irritation, try:
Lukewarm rather than very hot water
A gentle fragrance-free soap
Thorough but gentle drying
Applying moisturizer after washing
What Temperature Should the Water Be?
You don't need extremely hot water.
The CDC notes that water temperature does not appear to substantially affect germ removal, while hotter water can increase skin irritation and energy use.
Warm or cold running water is fine.
What matters much more is using soap, rubbing thoroughly, and rinsing well.
Do You Really Need to Wash for 20 Seconds?
Yes.
The CDC recommends scrubbing your hands with soap for at least 20 seconds.
An easy trick for children is to sing a short song while washing.
Make sure to clean:
Palms
Backs of hands
Between fingers
Fingertips
Around and underneath fingernails
Thumbs
Wrists
Then rinse thoroughly.
The Five Steps to Proper Handwashing
The CDC's basic process is simple:
1. Wet
Wet your hands with clean, running water.
2. Soap
Apply plain soap.
3. Scrub
Rub your hands together for at least 20 seconds, covering every surface.
4. Rinse
Rinse thoroughly under clean, running water.
5. Dry
Dry completely using a clean towel or air dryer.
Don't rush the process.
Technique matters more than buying the most expensive soap.
What About Bar Soap?
Bar soap is perfectly capable of cleaning hands effectively.
There's no need to assume that liquid antibacterial soap is inherently more hygienic.
At home, a bar of soap can be perfectly reasonable as long as it is stored appropriately and allowed to dry between uses.
In shared public settings, liquid soap dispensers may be more convenient.
Again, the type of soap matters less than proper handwashing.
What About Children?
Children should learn proper handwashing early.
Make it fun rather than frightening.
Teach children to wash:
Before eating
After using the bathroom
After playing outside
After touching animals
After coughing or sneezing
When their hands are visibly dirty
Keep sanitizer out of children's reach when it's not being supervised.
The CDC specifically recommends supervising young children when they use hand sanitizer because swallowing alcohol-based sanitizer can cause serious harm.
And remember:
Children do not need antibacterial soap to stay healthy.
Plain soap and water are sufficient for routine handwashing.
What About Older Adults?
Hand hygiene becomes particularly important for older adults because the consequences of certain infections can be more serious with age.
Older adults should continue practicing routine handwashing while avoiding excessive concern about eliminating every microorganism from their environment.
Good hand hygiene is valuable.
Constantly attempting to sterilize yourself is unnecessary.
When Might Antimicrobial Soap Be Appropriate?
There are specialized circumstances in which healthcare professionals may recommend antiseptic or antimicrobial products.
Hospitals, surgical settings, and certain medical procedures have different infection-control requirements from everyday household handwashing.
Consumer recommendations should not be confused with healthcare protocols.
If a physician recommends a particular antiseptic cleanser because of a medical condition, procedure, or infection-control requirement, follow that individualized advice.
The Bigger Picture: Hand Hygiene Isn't the Only Way to Prevent Infection
Handwashing is powerful, but it isn't a complete disease-prevention strategy.
Some respiratory infections spread primarily through the air, so handwashing alone cannot prevent every infection.
Other important strategies can include:
Staying home when you're sick
Covering coughs and sneezes
Improving indoor ventilation
Staying current on recommended vaccinations
Avoiding touching your eyes, nose, and mouth with unwashed hands
Cleaning high-touch surfaces when appropriate
Practicing food safety
Think of hand hygiene as one layer of protection in a larger infection-prevention strategy.

The Bottom Line
Antibacterial soap isn't better than regular soap for everyday disease prevention.
For most people, the best routine is remarkably simple:
🧼 Plain soap + running water + proper technique
When soap and water aren't available:
🧴 Alcohol-based hand sanitizer with at least 60% alcohol
The CDC recommends plain soap and water as the preferred method in most situations, while sanitizer provides an effective alternative when a sink isn't available.
And perhaps the most important lesson is this:
Don't spend more money trying to kill more germs. Spend more attention on washing your hands correctly.
Good hand hygiene doesn't require an antibacterial label, expensive products, or a complicated routine.
Sometimes the simplest approach really is the healthiest one.
