Essential Concepts
- The sanitize setting on a dishwasher uses higher heat to reduce germs on dishes, cookware, and kitchen tools.
- It is especially helpful for items that touch raw meat, eggs, or unwashed produce, and for homes with kids, older adults, or anyone with weaker immune systems.
- The sanitize cycle usually runs longer and hotter than a normal wash, so it should be used with some planning, not for every single load.
- Using sanitize correctly can support food safety in your kitchen without replacing good habits like hand washing and proper food storage.
- Learning when to use sanitize, which items are safe for high heat, and how it fits with other dishwasher settings helps you clean smarter instead of just running more cycles.
Why Home Cooks Overlook The Dishwasher Sanitize Setting
Most home cooks treat the dishwasher control panel like a light switch. Normal cycle, start, done. The extra buttons and icons can look confusing, so they stay untouched.
The sanitize setting is one of those features that often sits there unused. It does not look exciting, and it usually adds time to the cycle. When you are busy, that extra time feels like a hassle. Many people also assume that the regular wash is already “sanitizing,” so they never question what that special setting is doing.
In a typical home kitchen, though, certain items would benefit from a more intense clean than the standard cycle provides. High heat is one of the most reliable ways to reduce germs on hard surfaces. Your dishwasher can do that work for you, as long as you know which button to press and when to press it.
This guide explains how the sanitize cycle works, when to use it, and how to combine it with other dishwasher settings so your kitchen stays cleaner without wasting water or energy.
What Is The Dishwasher Sanitize Setting?
The sanitize setting is a high heat option that raises either the wash temperature, the final rinse temperature, or both. The goal is not just to remove food soil, but to reduce bacteria on items that can handle higher heat.
On your control panel, sanitize might appear as:
- “Sanitize”
- “Sani”
- “High Temp” or “High Temperature Wash”
- A small icon that looks like a plus sign inside a droplet or a similar symbol
Depending on the model, sanitize may be a separate button that you add to another cycle, or it might be part of a specific cycle labeled “Sanitize” or “Hygiene.”
How The Sanitize Cycle Works In Practical Terms
In simple terms, sanitize does two things:
- Uses hotter water than a normal cycle.
- Keeps that high temperature for a set amount of time.
The higher heat helps:
- Soften and remove grease and oils that cling to dishes.
- Reduce germs on hard surfaces like plates, stainless steel utensils, and glassware.
- Dry dishes more completely when combined with a heated dry option, which makes it harder for bacteria to grow back on damp surfaces.
It is not the same as sterilizing equipment in a medical setting. But for everyday home cooking, it can add an extra layer of safety, especially for items that have been in contact with raw foods.
How Is The Sanitize Cycle Different From A Normal Dishwasher Cycle?
A regular dishwasher cycle is designed to remove visible food soil and everyday residues. It usually uses moderately hot water and a combination of spray, detergent, and rinsing to get dishes visually clean. For most loads, that is enough.
The sanitize setting changes three main things.
Higher Temperatures
Normal dishwasher cycles often run at a moderate hot water temperature. The sanitize setting increases the heat, particularly in the final rinse. That combination of heat and time helps reduce bacteria more effectively than a standard rinse.
Longer Cycle Time
Sanitize usually adds time to the total wash. The dishwasher may:
- Extend the main wash period.
- Lengthen the final hot rinse.
- Add a hold time where the water stays at a specific temperature.
This is why the sanitize option is best used when you are not in a rush to empty the dishwasher.
Targeted Purpose
A regular cycle is for general cleaning. The sanitize cycle is meant for specific needs, such as:
- Items that touched raw meat, poultry, or seafood.
- Cutting boards and knives used for trimming or deboning.
- Baby bottles and some feeding accessories that are labeled dishwasher safe.
- Containers and lids that held raw eggs or unwashed produce.
Thinking about sanitize as a “targeted tool” instead of a daily default helps you use it in a smart, balanced way.
When Should Home Cooks Use The Sanitize Setting?
Most households do not need to run sanitize on every cycle. Instead, think about situations and items where a higher level of cleanliness is helpful.
After Handling Raw Meat, Poultry, or Seafood
Any time you chop raw chicken on a cutting board or use knives to trim pork or beef, those surfaces touch bacteria that can cause foodborne illness. Scraping off visible residue in the sink is only one part of the job.
Running those items through a cycle with sanitize helps:
- Reduce bacteria on the board and knives.
- Clean grooves and scratches where food residue can hide.
- Support safer cooking when you later use that same board for vegetables or bread.
For Homes With Babies, Young Kids, Or Older Adults
Some family members are more vulnerable to germs than others. Babies, toddlers, pregnant people, older adults, and anyone with a weaker immune system can be more affected by everyday bacteria that do not bother a healthy adult.
Using sanitize for:
- Sippy cups and dishwasher safe bottles.
- Plastic plates and trays that are labeled safe for high heat.
- Utensils used for feeding.
can offer extra peace of mind in a realistic way.
After Illness In The Household
If someone in your home has been sick with a stomach bug or a respiratory infection, sanitize can be part of your cleanup routine. Running utensils, cups, and other shared items on sanitize may help support a cleaner environment as everyone recovers.
For Food Storage Containers That Held Risky Foods
Containers that held raw egg mixtures, marinated raw meats, or juices from thawed meat are good candidates for a sanitize cycle. These dishes may look clean after a normal wash, but the added heat from sanitize further supports food safety.
When You Deep Clean The Kitchen
Many home cooks do a seasonal or monthly deep clean in the kitchen. That is a good time to:
- Load dishwasher safe utensil holders, spoon rests, and small organizing bins.
- Run them on a sanitize cycle together with sturdy dishes and tools.
It becomes part of a bigger routine that freshens the whole kitchen.
How Often Is It Smart To Use The Sanitize Setting?
There is no single rule that fits every household. The right frequency depends on your cooking habits and who lives in your home.
In many kitchens, a sensible pattern looks like this:
- Use sanitize a few times a week if you cook raw meat, poultry, or seafood often.
- Use sanitize more regularly for baby items that are labeled dishwasher safe.
- Use sanitize occasionally for a deep clean when you notice musty odors or buildup.
You can still rely on the normal cycle for simple loads like:
- Breakfast dishes that only held cereal or toast.
- Light lunch plates and glasses.
- Baking tools used only for dry ingredients.
Balancing both settings helps you get the benefits of sanitize without running extra long cycles every single day.
Can The Sanitize Setting Damage Dishes Or Cookware?
High heat is helpful for hard, durable items. It can be tough on certain materials, though, so it is important to match the setting with the objects you are washing.
Items That Usually Handle Sanitize Well
Most of the time, sanitize is safe for:
- Plain glass drinking glasses.
- Ceramic plates, bowls, and mugs that are labeled dishwasher safe.
- Stainless steel flatware and cooking tools.
- Many hard plastic items that are marked “dishwasher safe – top rack only.”
Always check the manufacturer mark under the item when you can.
Items To Avoid In High Heat
Some items do not belong in a sanitize cycle because the extra heat can:
- Warp thin or low quality plastics.
- Fade or peel designs and decals on certain dishes.
- Loosen glues or fillers inside insulated travel mugs or specialty cups.
- Damage wooden handles or cutting boards over time.
If a piece is labeled “hand wash only,” keep it out of the dishwasher entirely, not just out of sanitize. For anything that looks delicate, sentimental, or expensive, a gentle hand wash is still the safest choice.
Watching For Early Warning Signs
If you decide to try sanitize on a new item, watch it carefully over the first few washes. Look for:
- Warping or bending, especially in lids and plastic containers.
- Cracks in glazing or decorations.
- Cloudiness or film that does not rinse away.
If you see any of these changes, switch that item back to the normal cycle or wash it by hand.
How To Find And Use The Sanitize Setting On Your Dishwasher
It is easy to overlook sanitize if it is tucked into a menu or printed in small letters. A quick walkthrough of your control panel can help you find it.
Step 1: Read The Button Labels Slowly
Look along the control panel for words like “Sanitize,” “Sani,” “High Temp,” or “Hygiene.” On some models, sanitize may be a small secondary option under a main cycle.
If the controls use icons, look for:
- A droplet with a plus sign.
- A small symbol grouped with words like “extra clean” or “high temp.”
Step 2: Check The Cycle Chart
Many dishwashers have a small chart on the inside of the door or in the user booklet. It explains:
- Which main cycles can be combined with sanitize.
- How much time sanitize adds to the wash.
- Whether sanitize affects drying.
If you no longer have the booklet, a search using your model number often provides a digital version on the manufacturer’s site. Review it once, then keep a simple note on the inside of a cabinet door if that helps you remember your favorite combination.
Step 3: Start With One “Test” Load
Choose a load that includes:
- Sturdy plates and bowls.
- Stainless steel utensils.
- A few plastic items that are clearly marked dishwasher safe.
Run your usual cycle and activate sanitize. When the machine is finished, check the dishes for any signs of warping or damage.
Once you are comfortable, you can start using sanitize as part of your regular cleaning plan for specific types of loads.
How The Sanitize Setting Supports A Cleaner, Safer Kitchen Routine
Sanitize is not magic. It works best as one part of an overall kitchen routine that keeps germs under control.
Pair Sanitize With Good Sink Habits
Before items reach the dishwasher, a few simple steps help:
- Scrape plates and bowls to remove excess food.
- Rinse away thick sauces or sticky residues so the dishwasher can focus on cleaning instead of pushing chunks around.
- Keep the sink itself clean, so items are not sitting in dirty standing water.
Sanitize can then focus on high heat cleaning instead of fighting heavy buildup.
Combine Sanitize With Safe Food Handling
Even the best dishwasher cycle cannot fix unsafe food handling. Keep basic habits in place, such as:
- Storing raw meat and poultry on the lowest shelf of the refrigerator to avoid drips.
- Using separate cutting boards for raw proteins and ready to eat items when possible.
- Washing hands frequently, especially after handling raw meat or cracking eggs.
Once these habits are in place, sanitize becomes a useful final step for hard surfaces that have already been rinsed and loaded properly.
Use Sanitize To Control Odors And Film
High heat can help reduce:
- Sour smells from lingering food soil.
- Greasy film on glasses and utensils.
- Build up inside corners of the dishwasher itself.
If you notice that dishes smell stale, even after a normal cycle, or if the inside of the tub looks dull and greasy, run a sanitize cycle with a full load of sturdy dishes. It is a practical way to freshen both the contents and the machine.
Other Helpful Dishwasher Settings Home Cooks Forget To Use
While sanitize is the star of this topic, a few other settings can support a cleaner and more efficient kitchen. Used together, they help you get better results without extra work.
Eco Or Energy Saving Cycles
Eco cycles rely on slightly lower temperatures and longer soak times instead of constant high heat. They are useful for:
- Lightly soiled dishes.
- Loads that do not contain raw meat or risky foods.
- Days when you are not in a rush and want to use less energy.
A balanced approach is to reserve sanitize for higher risk items and use eco for simple loads like breakfast or snack dishes.
Delay Start
Delay start lets you set the dishwasher to run later. This can be helpful if:
- You want to avoid the sound of the dishwasher during dinner or a quiet evening.
- Your utility rates are lower at night, and you prefer to run long cycles like sanitize while you sleep.
Load the dishwasher after dinner, set sanitize if needed, and choose delay so the cycle finishes closer to the time you wake up. Dishes are ready when you start the day.
Half Load Or Zone Wash
Some dishwashers offer half load or zone wash settings, which focus water and cleaning on one rack. This is useful when:
- You have a small number of high risk items that need sanitize.
- You do not have enough dishes to fill the entire machine, but you still want the benefits of high heat.
If your machine treats sanitize as an add on, you can combine it with a half load setting to avoid wasting water on empty space.
Practical Tips For Using The Sanitize Setting Without Wasting Energy
Because sanitize adds heat and time, it is worth planning a little to use it efficiently. A few small habits make a big difference.
Group High Risk Items Together
Instead of scattering cutting boards, raw meat containers, and kids’ items across several days of normal loads, try to group them into one or two sanitize loads each week. This strategy:
- Reduces how often you run the longer cycle.
- Ensures the items that benefit most from high heat actually receive it.
Fill The Dishwasher Sensibly
Think about both cleanliness and water use:
- Do not overpack, which blocks spray arms and reduces effectiveness.
- Do not run sanitize for just a few plates unless those items truly need it.
- Add in sturdy everyday dishes when you are sanitizing high risk items, as long as they can tolerate the heat.
The goal is a thoughtful, full load, not an overloaded or half empty one.
Choose The Right Detergent Amount
Sanitize relies on heat, not extra detergent. Using more detergent than recommended can actually leave residue that looks cloudy or streaked. Follow the guidelines on the package and adjust only if your water is extremely hard or soft.
Keep The Dishwasher Clean
A dirty machine cannot clean dishes well, even with sanitize. From time to time:
- Check and clean the filter at the bottom of the tub.
- Wipe the door seals and the inside edge where food bits can collect.
- Run an empty hot cycle now and then with a dishwasher cleaner or a simple dishwasher safe cleaning routine recommended for your model.
Once the machine is clean, sanitize has a better environment to do its work.
Common Questions Home Cooks Have About The Sanitize Setting
Is Sanitize Needed If The Dishes Already Look Clean?
Looking clean and being cleaner on a microscopic level are not the same. A normal cycle handles most routine messes. Sanitize adds extra protection for specific items, especially those that touched raw foods or will be used by more vulnerable family members. You do not need it for every plate, but it is helpful for certain loads.
Does Sanitize Make Dishes Completely Germ Free?
No home appliance can promise a completely germ free surface. The sanitize cycle aims to significantly reduce bacteria to a safer level on dishwasher safe items. That is valuable, but it should sit alongside other safe cooking and cleaning habits.
Does Sanitize Use More Water And Energy?
Sanitize usually uses more energy because of the higher heat and longer run time. Water use varies by model, but the main increase comes from electricity to heat the water. That is why it helps to reserve sanitize for loads that truly benefit from it and to keep eco or normal cycles for simpler loads.
Is It Safe To Use Sanitize Every Day?
Many dishwashers are built to handle frequent use of sanitize, but that does not mean it is necessary for every load. Daily use can increase energy bills and may wear some plastics and finishes faster. Most homes do well with a mix of cycles, using sanitize for higher risk loads a few times a week or as needed.
Making The Sanitize Setting Part Of Your Regular Kitchen Routine
For most home cooks, the biggest shift is mental. Instead of treating your dishwasher as a simple on and off tool, think of it as a small cleaning system with choices that fit your day.
A realistic routine might look like this:
- Normal or eco during the week for everyday meals that do not involve risky foods.
- Sanitize for loads that include raw meat cutting boards, baby items, or dishes used during an illness in the home.
- Occasional sanitize cycles for utensil holders, small bins, and sturdy tools during monthly or seasonal deep cleaning.
By understanding what the sanitize setting does and when to use it, you can support food safety, reduce kitchen odors, and get more value from an appliance you already own. You are not adding more chores. You are adjusting a habit you already have, using one overlooked dishwasher button that deserves a little more attention.
