If you’re wondering how to clean a garbage disposal, you’ve come to the right place. In the video above, the team at CLR Brands walks you through a quick, effective cleaning routine. Below, we’ve expanded that guidance into step-by-step instructions, tips for maintenance, and best practices to keep your kitchen sink area fresh and worry-free.
Why Clean Your Garbage Disposal?
Your garbage disposal is the workhorse under your kitchen sink, grinding food scraps and sending waste down the drain. But over time:
-Food particles, grease, and residue can build up inside the disposal chamber and splash guard, causing odors, slow drainage or poor performance.
-Even if it appears to be working, hidden buildup can lead to premature wear or clogging.
-Using the right product, such as CLR Garbage Disposal, can help clean, freshen and maintain the unit more effectively than basic rinse-and-wash alone.
By following the steps below, you’ll know how to clean garbage disposals correctly, help prolong the life of your unit, and avoid unpleasant smells or backups.
Step-by-Step: How to Clean a Garbage Disposal
Here’s a proven routine for cleaning your garbage disposal. Be sure to follow all safety steps carefully.
Step 1: Power Off & Inspect
First things first: turn off the power. Either unplug the disposal (if accessible) or switch off the circuit breaker. Always assume the disposal could turn on.
Next, shine a flashlight into the disposal chamber and look for large pieces of food, utensils or other debris. If you see something, use tongs or pliers to remove it (never your fingers).
Why this matters: You’re reducing safety risks and making sure the disposal can run freely during cleaning.
Step 2: Clean the Splash Guard & Chamber
Remove or lift the rubber splash guard (the black flaps over the disposal opening). Clean both sides using a long-handled brush and dish soap. The underside of the guard traps the most residue and odor-causing gunk.
Then, with the power still off, pour a small amount of hot (but not boiling) water into the drain to help loosen residue. This step readies the unit for the deeper cleaning treatment.
Step 3: Apply CLR Garbage Disposal Cleaner
Now it’s time to use the featured product: CLR Garbage Disposal. Follow the directions on the label. In the video you’ll see the team pouring the cleaner into the disposal chamber, letting it sit for a few moments to do its work, and then running cold water while turning on the disposal.
Using a specially-formulated cleaner like CLR means you’re tackling hidden buildup, mineral deposits and odors in one go. This is especially helpful if your disposal is in a home with hard-water challenges.
(Optional: If you like additional natural freshness, you can add a few citrus peel strips in the next step.)
Step 4: Grind Ice & Salt (Optional, but Recommended)
After you’ve used the CLR Garbage Disposal pod and run water to rinse, you can further clean the grinding chamber by pouring in about 2 cups of ice cubes and 1 cup of kosher or rock salt, then turning on the cold-water tap and running the disposal until the ice is shredded.
The ice and salt act as a mechanical scrub of the blades and inner surfaces, helping remove stuck-on grime without damaging the unit. This step is a shining compliment to using CLR Garbage Disposal.
Step 5: Flush with Cold Water & Finish
Finally, keep the cold-water tap running for 15-20 seconds after you turn off the disposal. This helps wash away any loosened debris and ensures the unit is clear.
If you like, toss in a few lemon or orange peel strips, run the disposal with cold water for about 10 seconds, and you’ll have a fresh scent going forward.
Return the splash guard or its flaps, restore power, and you’re done.
Best Practices & Maintenance Tips
Here are key tips to keep your garbage disposal running smoothly and to reduce how often you’ll need full-cleanings.
What You Shouldn’t Put in a Garbage Disposal
Avoid these items, as they can damage your unit or lead to clogs:
-Grease, oils and fats; these can solidify and block pipes.
-Fibrous vegetables (corn husks, celery stalks), large bones, fruit pits, eggshells; these are either too tough or too stringy.
-Pasta, rice, coffee grounds; they may clog or expand after the fact.
How Often to Clean Your Garbage Disposal
If you use your disposal daily, you should perform the full sink cleaning routine once a week. If you use it less, every 1–2 months may suffice. Pay attention for signs you need a cleaning sooner:
-Foul odor emanating from the disposal or sink.
-The disposal sounds slower or quieter than usual.
-Poor drainage or water backing up.
Quick Upkeep Between Deep-Cleans
-Run cold water for 10–15 seconds after every use of the disposal.
-Once a week, drop a few ice cubes into the disposal and run it with cold water for about 5 seconds; this gives a quick blade scrub.
-Consider using CLR Garbage Disposal once per week for a proactive clean and freshen.
-Don’t skip the splash guard cleaning; it’s a frequent odor culprit.
Why CLR Garbage Disposal Makes a Difference
While DIY methods using baking soda, vinegar, ice and salt (or citrus peels) are common and helpful, a product formulated specifically for the job adds advantages:
-A cleaner like CLR is designed to handle mineral deposits, grease residue and hidden buildup more efficiently than home-remedies alone.
-Using CLR gives you confidence you’re using a product built for that appliance, making the process quicker and often more effective.
-Especially in households with hard-water or heavy usage, using a professional cleaner can extend the life of your disposal and reduce the risk of odors or clogs.

Common Questions about How to Clean a Garbage Disposal
Q: Can I skip unplugging the disposal and just turn off the switch?
A: No. Always ensure the power is fully off (unplug or switch off breaker) before reaching into or working with the disposal. Safety first.
Q: What if my disposal keeps smelling even after cleaning?
A: If odors persist after using CLR Garbage Disposal and doing the ice/salt scrub, check for hidden debris stuck under the splash guard or inside the drain pipe. Also review what you're feeding into the unit and ensure you’re flushing with plenty of cold water.
Q: Is it okay to use hot water when running the disposal?
A: It’s best to use cold water when grinding. Hot water can liquify fats and oils in the chamber or pipes and cause build-up later.
Q: Can I just pour baking soda and vinegar into the disposal instead of using CLR?
A: Yes, many DIYers do. Methods using baking soda + vinegar or ice + salt are effective. But using a purpose-made product like CLR is faster, formulated for the task, and gives strong results without you needing to assemble multiple supplies.
