How to Clean a Slow Cooker with Natural DIY Cleaner

We all love the convenience of slow cooking. I mean, you simply dump in the ingredients, chill out, and BOOM: a slow-simmered, super flavorful meal. But if you're under the impression that the cleaning up part isn't quite as easy, we're here to tell you otherwise—even if you've made a sticky toffee pudding and left the crusty remnants to dry inside overnight like we did. For demonstration purposes, of course, because we'd never be that lazy in real life (ahem). Not only can you clean it up with little effort, you don't even have to buy any special cleaners to get the job done. Here's how!

Step 1: "Cook Out" Stubborn Messes First

If you've got a fair amount of stuck-on food (as our sticky toffee pudding left us with below), you may need to complete this step before using your DIY cleaner.

Fill your slow cooker with water and add distilled white vinegar (1/2 cup for a 3-quart cooker and 2 cups for a 6 quart). Then, set to low and let "cook" for 2 hours. This should make easy work of your cleanup afterwards!

Step 3: Clean Outer Pot

Warning

Safety first! Unplug your slow cooker (or any small appliance, for that matter) before cleaning.

Using a non-scratch scouring pad, use the paste to clean off any food stains on the outer pot.

If you're able to remove the inner pot in order to reach the heating element at the bottom of the outer pot, use the cleanser to scrub this area also. (Before doing so, please read the warning below).

Warning

Refer to your product manual for detailed cleaning instructions for your particular slow cooker model. In general, the heating element should not be immersed nor rinsed with water which can cause damage and/or injury.

Step 4: Wipe Off with Microfiber Cloth

Once scrubbing is complete, wipe off the paste with a microfiber cloth. No water is required! Ensure that the heating element portion is entirely free of residue before using your cooker again.

Step 5: Scrub Inner Pot

Repeat steps 2 and 3 for the inner pot—first scrubbing on, then wiping off. Ensure that you don't scrub too hard so as not to scratch the stoneware. If you've completed an initial phase of "cooking out" the burnt-on food with water and vinegar, you shouldn't need to use much elbow grease. However, if food is still stuck on, you may need to repeat the vinegar-water process.
