A dirty crockpot can look impossible to clean when burnt sauce, sticky grease, and dark baked-on food stains are stuck to the bottom and sides. Slow cookers are useful for easy meals, but when food cooks for hours, sauces and oils can dry onto the ceramic insert and leave behind a stubborn mess.
The crockpot shown here has heavy brown and black buildup inside. The bottom is covered with burnt residue, and the sides have dried food splatters from cooking. Instead of throwing it away or using harsh scrubbing tools, you can try a simple cleaning method using baking soda, hot water, and dish soap.
This method helps soften stuck-on food, loosen burnt grime, and make the crockpot easier to scrub clean.
Why Crockpots Get So Dirty
Crockpots cook food slowly for several hours. This is great for soups, stews, sauces, meats, and casseroles, but it also means food has more time to stick to the sides.
Common reasons a crockpot becomes dirty include:
- Sauce drying onto the walls
- Food burning at the bottom
- Grease sticking to the ceramic insert
- Leftovers sitting too long after cooking
- Thick meals like chili, cheese dishes, or tomato sauce splattering inside
- Not soaking the insert before washing
Once food dries and hardens, normal dish soap may not be enough. That is when baking soda and hot water can help.

Important Safety Note Before Cleaning
Before cleaning any crockpot, make sure it is turned off, unplugged, and completely cool.
If your crockpot has a removable ceramic insert, remove it from the electric base before washing. Never submerge the electric base in water. Only clean the removable pot and wipe the outside base carefully with a damp cloth.
Step 1: Sprinkle Baking Soda Inside the Crockpot
Start by sprinkling a generous amount of baking soda directly inside the dirty crockpot. Focus on the worst areas, especially the bottom where the food is burnt and stuck.
In the video, the white powder is added directly over the dark brown and black stains. This is important because baking soda works best when it touches the dirty surface.
Use enough baking soda to lightly cover the stained area. For a very dirty crockpot, do not be afraid to use a little more.
Step 2: Add Hot Water
Next, slowly pour hot water into the crockpot. The water helps activate the baking soda and begins softening the dried-on food.
You do not need to fill the entire crockpot to the top. Add enough hot water to cover the bottom and reach the stained areas. If the sides are very dirty, you can add a little more water so the buildup has time to soften.
The mixture may start to look cloudy and foamy. This is normal.
Step 3: Add a Small Amount of Dish Soap
Add a few drops of dish soap to the hot water and baking soda mixture. Dish soap helps break down grease, oily food residue, and sticky sauce stains.
Do not use too much soap. A small amount is enough to help the cleaning process.
Step 4: Let It Soak
Let the mixture sit inside the crockpot for at least 15 to 30 minutes. If the crockpot is extremely dirty, you can let it soak longer.
This soaking time is very important. It gives the hot water, baking soda, and dish soap time to loosen the stuck-on food before scrubbing.
For very heavy burnt buildup, you can leave the mixture inside for one hour.
Step 5: Scrub with a Sponge
After soaking, use a sponge to scrub the bottom and sides. Move the sponge in circular motions over the dirty areas.
You should start to see the brown residue lifting away. The water may become darker as the burnt food breaks loose.
Do not use a metal scraper or steel wool on a ceramic crockpot insert because it may scratch the surface. A sponge or soft scrub brush is safer.
Step 6: Use a Brush for Stubborn Spots
If some stains are still stuck, use a dish brush to scrub those areas. A brush can reach curved corners and side walls better than a sponge.
In the video, the brush helps remove the darker stains around the bottom. This step gives the cleaning method a stronger finish without needing harsh chemicals.
Scrub gently but firmly until the residue starts to loosen.
Step 7: Rinse and Wipe Clean
Pour out the dirty water and rinse the crockpot with warm water. Use a clean sponge or cloth to wipe away any leftover baking soda or loosened food residue.
If the crockpot still has a few stubborn spots, repeat the process:
- Add baking soda
- Add hot water
- Add dish soap
- Soak again
- Scrub again
Very dirty crockpots may need two rounds, especially if the food has been burnt for a long time.
Before and After Cleaning
Before cleaning, the crockpot may look dark, greasy, and stained. The bottom can be covered with burnt food, and the sides may have dried sauce marks.
After cleaning, the inside should look much smoother, fresher, and shinier. The dark residue should be removed or greatly reduced, and the crockpot should look ready to use again.
This simple method is satisfying because the transformation is easy to see.
Why Baking Soda Works So Well
Baking soda is useful for cleaning because it has a mild abrasive texture. It helps scrub away grime without being too harsh.
It also helps reduce food odor, which is useful when a crockpot has been used for strong-smelling meals like chili, stew, barbecue sauce, or garlic-heavy recipes.
When combined with hot water and dish soap, baking soda becomes even more effective for loosening cooked-on residue.
Best Tips for Better Results
Use Hot Water, Not Cold Water
Hot water softens dried food faster than cold water. This makes scrubbing easier.
Let It Sit Before Scrubbing
Do not scrub immediately. Soaking gives the mixture time to work.
Focus on the Bottom First
The bottom usually has the worst burnt residue, so clean that area first.
Avoid Metal Tools
Metal scrapers can damage the crockpot insert. Use a sponge or soft brush instead.
Repeat for Heavy Stains
One cleaning round may not remove everything if the crockpot is badly burnt. A second round can make a big difference.
Common Mistakes to Avoid
Cleaning While the Crockpot Is Still Hot
Always let it cool first. Sudden temperature changes can damage some ceramic inserts.
Using Too Much Force
Heavy scrubbing with rough tools can scratch the surface. Let the soaking process do most of the work.
Submerging the Electric Base
Only wash the removable insert. The heating base should never be soaked in water.
Leaving Food Overnight
The longer food stays stuck inside, the harder it becomes to clean.
Using Harsh Chemicals Too Quickly
Try this simple cleaning method first before reaching for strong cleaners.
How to Keep Your Crockpot Cleaner Next Time
A few simple habits can prevent heavy buildup:
- Spray or lightly oil the insert before cooking sticky meals
- Stir thick sauces when possible
- Avoid overcooking meals until they dry out
- Remove leftovers soon after cooking
- Soak the insert right after use
- Wash before food hardens
- Use slow cooker liners if you want easier cleanup
These small steps can save a lot of cleaning time later.
Can This Method Remove Burnt Smell?
Yes, it can help. Burnt food often leaves a strong smell inside a crockpot. Baking soda helps absorb odor, while dish soap removes greasy residue that holds the smell.
If the smell is still there after cleaning, sprinkle a little baking soda inside the dry crockpot and leave it for a few hours before rinsing again.
Can You Use Vinegar Too?
Yes, vinegar can be used as an optional extra. If the stains are very stubborn, you can add a small splash of white vinegar after the baking soda. It may fizz and help loosen residue.
However, hot water, baking soda, and dish soap are usually enough for many dirty crockpots.
Frequently Asked Questions
Can I clean a crockpot with baking soda?
Yes. Baking soda is one of the easiest household ingredients for loosening stuck-on food and reducing odor.
How long should I soak a dirty crockpot?
For normal buildup, 15 to 30 minutes may be enough. For heavy burnt food, soak it for up to one hour.
Can I use a scrub brush?
Yes, but use a soft dish brush. Avoid metal brushes or steel wool on ceramic inserts.
Is dish soap necessary?
Dish soap helps remove grease, so it is very useful when the crockpot has oily or sticky residue.
Can I clean the electric base with water?
Do not submerge the electric base. Wipe it with a damp cloth only after unplugging it.
What if the stain does not come off the first time?
