The Sanitize cycle on Samsung washers is a specialized wash setting designed to kill common household bacteria and germs by using high-temperature water and a longer wash time. Depending on the model, this cycle typically reaches temperatures of around 150°F (66°C) or higher and can last from 90 to 180 minutes. It’s ideal for towels, bed linens, children’s clothing, and other frequently used items that need a deeper clean than a regular wash cycle.
What Is the Samsung Washer Sanitize Cycle?
Modern washing machines have many cycle options, but one of the most useful for health-conscious families is the Sanitize cycle. Samsung designed this cycle to help reduce bacteria and germs on washable fabrics by combining hot water, a long wash, and a powerful rinse cycle.
While the regular cycle focuses primarily on removing dirt and stains, the Sanitize cycle is specifically designed to improve the hygiene of fabrics. The washer uses a higher temperature than the normal setting, which helps target and destroy microorganisms that may remain on fabrics after a regular wash.
Many homeowners use this cycle during cold and flu season, after an illness, or whenever clothes need a deeper clean.

How Does the Samsung Sanitize Cycle Work?
The Sanitize cycle works by keeping the water temperature significantly higher throughout the wash cycle. Heat is one of the most effective ways to reduce bacteria and certain germs on clothes.
During this cycle, the washer carefully controls the water temperature and wash duration to maximize the effectiveness of the sanitization. Depending on the model, the machine may extend the duration of the wash and subsequent wash steps to ensure that the clothes receive sufficient heat.
This combination of hot water, detergent effectiveness, and mechanical agitation helps clean clothes better than a regular washing program.
What Temperature Is the Samsung Sanitize Cycle?
One of the most frequently asked questions is what temperature the water should be in the Sanitize cycle.
Most Samsung washers with a Sanitize cycle heat the water to around 150°F (66°C) or higher. This high temperature helps reduce many common household bacteria and germs that can survive washing at lower temperatures.
The exact temperature may vary slightly depending on the washer model, the water temperature used, and the type of fabric. However, the main goal remains the same: to create improved sanitation compared to a regular wash cycle.
Because of this high temperature, fabrics must be able to withstand hot water before using this cycle.

Does the Samsung Sanitize Cycle Kill Bacteria?
Yes, the Samsung Sanitize cycle is specifically designed to kill many common bacteria on household fabrics.
High-temperature washing has long been recognized as one of the most effective methods for improving laundry hygiene. When combined with the use of the right detergent, the Sanitize cycle helps reduce the number of microorganisms that can accumulate on frequently used items.
However, it is important to understand that no household washer can guarantee complete disinfection of every item of clothing. This cycle is designed to sanitize fabrics rather than create a sterile environment.
For everyday household use, this cycle provides a significantly higher level of hygiene than a regular wash cycle.
When Should You Use the Samsung Sanitize Cycle?
When clothes need more than just a little cleaning, the Sanitize cycle is most beneficial.
Many families use this setting for towels, as towels often contain moisture and can harbor bacteria. It’s another popular choice because bed sheets and pillowcases are in contact with the skin for extended periods of time.
Parents often use this cycle for children’s clothing, blankets, and washable cloth toys. Sick family members can choose the Sanitize cycle to clean their used clothes and sheets.
Pet bedding, reusable cleaning cloths, and sportswear can also benefit from the extra cleaning power of this cycle.

What Items Should Not Be Washed on Sanitize?
While this cycle cleans well, it is not suitable for all types of fabrics.
Delicate fabrics such as silk, wool, lace, and some synthetic fabrics can be damaged by exposure to very hot water. Some garments may shrink, fade, or lose their shape after repeated sanitizing washes.
Always check the care label before selecting a cycle. If the manufacturer recommends using only cold or warm water, using sanitize may reduce the durability of the fabric. For delicate items, the gentle cycle is the safest option.
How Long Is the Samsung Washer Sanitize Cycle?
The Sanitize cycle is usually much longer than a regular wash cycle.
Depending on the Samsung washer model, the duration of this cycle can range from about 90 minutes to about 3 hours. This is necessary because the machine needs to maintain a high water temperature while ensuring adequate washing and cleaning performance.
Many users are surprised by the length of this cycle, but this extended duration is an important part of achieving effective sanitization.
The exact time displayed on the control panel while the washer is running may also vary as the washer adapts to the load conditions.
Samsung Sanitize Cycle vs Normal Cycle
The biggest difference between the Sanitize cycle and the Normal cycle is the cleaning purpose.
The Normal cycle is designed for everyday laundry and balances cleaning performance and efficiency. It uses medium-temperature water and a short wash time, which is suitable for most clothes.
The Sanitize cycle prioritizes hygiene. Higher temperatures and longer wash times help reduce germs, but they also increase water and energy usage.
The Normal cycle is usually sufficient for regular clothes. The Sanitize cycle should only be used when a more thorough clean is needed.

Does the Sanitize Cycle Use More Electricity?
Yes, the Sanitize cycle typically uses more energy than a regular wash program.
The main reason for this is the heating of the water. Compared to washing in cold or hot water, it takes additional energy to raise the temperature of the water to sanitize.
This cycle can use more water and run for a longer period of time, which increases overall energy use. While this increase in energy use is noticeable, many homeowners find the added health benefits worth it for certain fabrics.
Common Mistakes When Using Samsung Sanitize Cycle
A common mistake is to use this cycle every time you wash clothes. While its extra cleaning power can be helpful, it is often unnecessary for lightly soiled clothes.
Another mistake is to wash delicate fabrics that cannot withstand high temperatures. Over time, repeated exposure to hot water can damage certain fabrics.
Loading too many clothes into the washer can also reduce cleaning efficiency. Clothes need enough space to move freely so that water and detergent can reach all surfaces of the fabric.
Using the correct amount of HE detergent and following the garment care instructions will help you get the best results.
Why Isn’t the Sanitize Option Available?
Some Samsung washer models limit the number of cycles available depending on the selected settings.
If incompatible fabric settings, temperatures, or special cycles have already been selected, the Sanitize option may be unavailable. In other cases, certain washer models lack a separate Sanitize feature.
Reviewing the owner’s manual can help determine which cycles support the sanitizing function on your specific machine.
Final Thoughts
The Samsung Washer Sanitize Cycle is one of the most powerful cleaning options available on modern Samsung washing machines. Combining high temperatures, long wash times, and thorough rinsing, it helps reduce bacteria and improve laundry hygiene on items like towels, bed sheets, baby clothes, and frequently used clothes.
Although this cycle uses more time and energy than a regular wash, it can be invaluable when a deeper clean is needed. By understanding when to use the Sanitize Cycle and when to choose a different setting, you can get cleaner, fresher laundry and extend the life of your clothes.
