When a sink smells, the disposal usually gets the blame, and often it is the disposal. InSinkErator says a smell is usually a sign of food buildup, and much of it sits where water never reaches. A cleaner can help, but only one made for the job, and only after you have done the free part.
This guide covers eight garbage disposal cleaners from named makers, from foaming tablets to quick capsules. We have not used them ourselves, and we found no controlled comparison worth citing. We tell you what each maker says, and where that ends. Nothing here promises more than the box does.

Quick verdict: the best garbage disposal cleaner for most sinks
Start with Affresh Garbage Disposal Cleaner, a foaming tablet that names the grind chamber, impeller and drain pipe. For a smell that has already set in, use Glisten, whose foam goes under the splash guard. Scrub the baffle by hand first, which may solve it without buying anything.
InSinkErator’s Eric Schultz tells Consumer Reports to look for products specifically formulated for disposal cleaning, because some cleaners contain corrosive materials. Never pour a chemical drain opener into a disposal.

Our picks for the best garbage disposal cleaner
Foaming products come first, then quick capsules, then the enzyme and probiotic options.
1. Affresh Garbage Disposal Cleaner, 12 Tablets – Foaming Year’s Supply
Affresh is our first choice for its clear claims and its plain statement about who stands behind it. The listing says its foaming action targets the smell of rotting food debris and grime in the grind chamber, impeller and drain pipe, and leaves a citrus scent. It also says it is EPA Safer Choice certified and septic safe.
It calls itself the number one recommended disposal cleaner brand by Whirlpool and KitchenAid, then discloses that Affresh and those brands are all owned by Whirlpool Corporation. That honesty is worth noting, and it also tells you not to read the recommendation as an outside opinion. Twelve tablets are sold as a year’s supply. We read no controlled comparison of disposal cleaners, so this rests on the listing and on the advice below about choosing a product made for the job.
Why we like it
- Made specifically for disposals
- EPA Safer Choice certified, per the listing
- Discloses the ownership behind its recommendation
Key specifications
| Model | W11756281 |
|---|---|
| Count | 12 tablets |
| Format | Foaming tablet |
| How often, per maker | Year’s supply, per the listing |
| Scent | Citrus |
| Key ingredient or claim | Foam for grind chamber, impeller, drain pipe |
| Septic note | Septic safe, per the listing |
| Directions in brief | Follow the box |
Why we recommend it
This suits most homes that want a once-a-month routine from a large appliance company’s cleaning brand.
Skip it if you want the plainest, lowest-effort routine. Plink’s capsules are simpler still.
Pros and cons
Pros
- Clear target areas
- Certification stated
- Sold directly by Amazon when we checked
Cons
- Recommendation comes from its own parent company
- Schedule is implied by the year’s-supply wording
- No independent comparison to cite
2. Glisten Garbage Disposer Cleaner, Lemon, 4 Packets – Foam Under the Splash Guard
Glisten is a long-running name for this job, and its listing is the most specific about where the foam goes. It says the foam scrubs the disposer’s sidewalls, blades and the area under the splash guard. That last spot matters, because Consumer Reports says odors often come from the splash guard.
Glisten suggests weekly use to help prevent buildup and keep the disposer running well, so four packets last about a month. That makes it more of a focused treatment than a long-term supply, though larger packs are sold. The listing says it is made in the USA and carries a satisfaction guarantee. If a smell has already set in, this is the one we would reach for first.
Why we like it
- Names the splash guard, a common odor source
- Foam reaches the sidewalls and blades, per the listing
- Lemon scent
Key specifications
| Model | DP06N-PB |
|---|---|
| Count | 4 packets |
| Format | Foaming powder packet |
| How often, per maker | Weekly |
| Scent | Lemon |
| Key ingredient or claim | Foaming action |
| Septic note | Not stated on this listing |
| Directions in brief | Follow the box |
Why we recommend it
Choose it when the disposal already smells and you want a foam aimed at the places that cause it.
Skip it if you want a long supply. Four packets go quickly at one a week.
Pros and cons
Pros
- Specific about where it works
- Made in the USA, per the listing
- Sold directly by Amazon when we checked
Cons
- Short supply at weekly use
- Packets take a little more handling than a drop-in capsule
- Maker’s claims only
3. Plink Garbage Disposal Cleaner, Lemon, 40 Count – Quick Drop-In Capsules
Plink is the easy habit. You drop a capsule in and run the disposal with bursts of hot water, according to the listing. The maker suggests using it at least twice a week or as needed, so the 40-count pack lasts around five months.
Think of it as freshening more than deep cleaning. The listing talks about removing tough odors and reaching into crevices, and describes the formula as using a bleach alternative. There is one point to weigh: the listing mentions hot water, while InSinkErator’s advice is to run cold water when grinding food. Follow the box for the capsule and use cold water for ordinary food waste. The seller we saw was a third party, so check the listing when you buy.
Why we like it
- Quickest routine here
- Large count
- Bleach alternative, per the listing
Key specifications
| Model | PLM40N |
|---|---|
| Count | 40 capsules |
| Format | Capsule |
| How often, per maker | At least twice a week |
| Scent | Lemon |
| Key ingredient or claim | Bleach alternative |
| Septic note | Not stated on this listing |
| Directions in brief | Drop in, run with bursts of hot water |
Why we recommend it
This fits a kitchen that uses the disposal daily and would rather do a few seconds of upkeep often than a real clean monthly.
Skip it if you have heavy buildup. Foam is the better tool for that.
Pros and cons
Pros
- Simple
- Pack lasts a while
- Lemon scent
Cons
- More of a freshener
- Third-party seller when we checked
- Frequent use needed
4. Lemi Shine Foaming Garbage Disposal Cleaner, 2 Count – Citric Acid Foam
Lemi Shine uses citric acid as the active cleaner, and the listing says the foam helps break down grease, food scraps and buildup. It also claims the formula removes odors at the source and is not just a cover-up. The listing says Lemi Shine has been named an EPA Safer Choice Partner.
The 2-count box is a small trial size, so buy this to see if you like it, and move up to the 16-pack if you do. Because it is acidic, keep it away from any bleach product, the same as you would with any acid cleaner. Sold by Lemi Shine when we checked, which is a small comfort with cleaning products that move through many resellers.
Why we like it
- Citric acid is the named active
- Foaming action
- Sold by the maker when we checked
Key specifications
| Model | 00136 |
|---|---|
| Count | 2 count |
| Format | Foaming cleaner |
| How often, per maker | Not stated on the listing |
| Scent | Natural fresh scent |
| Key ingredient or claim | Citric acid |
| Septic note | Not stated |
| Directions in brief | Follow the box |
Why we recommend it
It suits a buyer who likes knowing the active ingredient, or who already uses Lemi Shine elsewhere in the kitchen.
Skip it if you want a long supply. This box holds only two.
Pros and cons
Pros
- Clear active ingredient
- Good small trial pack
- Larger packs sold
Cons
- Very small pack
- Don’t mix with bleach
- Maker’s claims only
5. Arm & Hammer Sink Garbage Disposal Cleaner, Citrus, 12 Count – Baking Soda Capsules
Baking soda is a kitchen staple for disposals. InSinkErator’s Eric Schultz tells Consumer Reports that ice and baking soda help scour the grind mechanism. Arm & Hammer puts it in a capsule with a citrus scent. The steps are specific: run the disposal and water for a minute, turn off the disposal and slow the water to a stream, drop in a capsule and run the disposal for 15 seconds.
The listing is about deodorizing and doesn’t claim to remove heavy buildup, so that is the job to buy it for. Note that you could get a similar idea with a box of baking soda and some ice, as Consumer Reports’ article discusses. What you pay for is the convenience. The seller was a third party when we checked.
Why we like it
- The clearest step-by-step of any listing here
- Familiar baking soda formula
- 15-second run
Key specifications
| Model | 56344 |
|---|---|
| Count | 12 capsules |
| Format | Capsule |
| How often, per maker | Not stated on the listing |
| Scent | Citrus |
| Key ingredient or claim | Baking soda |
| Septic note | Not stated |
| Directions in brief | Flush one minute, slow the water, drop in, run 15 seconds |
Why we recommend it
It suits someone who wants a clear routine and a mild deodorizer from a known household name.
Skip it if you already keep baking soda and ice in the kitchen and don’t mind a little effort.
Pros and cons
Pros
- Clear directions
- Familiar brand
- Mild approach
Cons
- Deodorizing and not deep cleaning
- Third-party seller when we checked
- Maker’s claims only
6. Rejuvenate Disposal Cleaner Pods, Lemon, 6 Count – Bio-Enzymatic Pods
Rejuvenate takes an enzyme-based approach to disposals. The listing says the bio-enzymatic pods help break down leftover food waste and deodorize disposals and pipes, with a foaming action and a lemon scent. Use one a week to prevent buildup and odors, which means six pods last about six weeks.
The listing gives few other details: no statement on septic use, no list of what the enzymes are, and no independent review that we read. If you already like enzymatic cleaners for drains, it is a reasonable option. If you just want an answer to a bad smell, a foaming product aimed at the splash guard is the more direct fix.
Why we like it
- Enzyme approach to food waste
- Foams, per the listing
- Weekly use is easy to remember
Key specifications
| Model | RJ6DPC-LEMON |
|---|---|
| Count | 6 pods |
| Format | Foaming pod |
| How often, per maker | Weekly |
| Scent | Lemon |
| Key ingredient or claim | Bio-enzymatic formula |
| Septic note | Not stated |
| Directions in brief | Follow the box |
Why we recommend it
It is for a buyer who prefers enzymes and wants a weekly routine rather than a monthly one.
Skip it if you want more detail than the listing gives.
Pros and cons
Pros
- Different method from acid or baking soda
- Sold directly by Amazon when we checked
- Lemon scent
Cons
- Short supply at weekly use
- Sparse listing
- Maker’s claims only
7. Frigidaire ReadyClean Sink and Disposer Cleaner, 6 Count – Monthly Probiotic Packet
Frigidaire’s packet works differently from the rest. You tear it open, pour it into the sink drain and wait: an hour for routine cleaning or overnight for serious odor, according to the listing. Then you use the sink as normal. The maker says one packet lasts a month and that the probiotic keeps working during normal use.
The listing also says it is safe for drains and pipes, has no bleach or boric acid, and works on all brands of sinks, drains and disposers. It carries a 30-day limited warranty. Because the cleaning action happens while it sits, it also suits a sink drain without a disposal, which most others here do not. We read no independent review of the probiotic claim, so treat that as the maker’s statement.
Why we like it
- Also treats a plain sink drain
- No bleach or boric acid, per the listing
- One packet a month
Key specifications
| Model | 10FFPROS02 |
|---|---|
| Count | 6 packets |
| Format | Probiotic powder |
| How often, per maker | Every 30 days |
| Scent | Not stated |
| Key ingredient or claim | Probiotic with surfactants and odor control |
| Septic note | Not stated |
| Directions in brief | Pour in drain; wait one hour, or overnight for odor |
Why we recommend it
Choose this if your drain smells as well as your disposal, or if you can leave a sink alone overnight.
Skip it if you need the sink in use for the waiting period.
Pros and cons
Pros
- Covers drain and disposer
- Monthly
- Sold directly by Amazon when we checked
Cons
- Needs waiting time
- Claims are the maker’s own
- No scent detail
8. Bastion Garbage Disposal Cleaner Drops, Lemon Zest, 50 Count – Large Pack of Citrus Drops
Bastion is an Amazon-first brand, and the appeal is a 50-count pouch. The active ingredient is d-limonene, which the listing says comes from citrus peels and helps break up fats, oils and food particles. The directions are similar to Arm & Hammer’s: run with hot water, turn off, slow the water to a thin stream, drop in one and run for 15 seconds.
It suggests use twice a week, so the pouch lasts about six months. The listing says it is septic safe and backs it with a 30-day money-back guarantee. There is no outside evidence we can point to, so don’t weigh the marketing language heavily. Also note the hot-water direction, and keep to cold water for ordinary grinding, as InSinkErator advises.
Why we like it
- Named active ingredient
- Long-lasting pouch
- Clear steps
Key specifications
| Model | Not stated |
|---|---|
| Count | 50 drops |
| Format | Drop |
| How often, per maker | Twice a week |
| Scent | Lemon zest |
| Key ingredient or claim | D-limonene |
| Septic note | Septic safe, per the listing |
| Directions in brief | Run hot water, slow the stream, drop in, run 15 seconds |
Why we recommend it
This is for a heavy disposal user who wants a big supply of a simple freshener.
Skip it if you prefer an established brand or a stated certification.
Pros and cons
Pros
- Large count
- Resealable pouch, per the listing
- Money-back guarantee, per the listing
Cons
- Amazon-first brand
- No independent evidence
- Freshener more than deep cleaner
How to choose a garbage disposal cleaner
First, try the free fix
InSinkErator links odors to food buildup. Its FAQ suggests scrubbing the underside of the sink baffle with a scouring pad, then running a medium stream of cold water, and dropping in ice cubes with lemon or lime wedges to freshen the unit. Do that first. It may be all you need, and you will know the splash guard is clean before you judge a product.
Foam or capsule
Foaming products such as Affresh and Glisten are aimed at buildup in the chamber. Capsules such as Plink and Arm & Hammer are quick fresheners. If you bought one kind and the smell came back, try the other.
What not to put in
Consumer Reports says never to put lye or chemical drain cleaners into a disposal, and quotes InSinkErator’s Eric Schultz saying some cleaners contain corrosive materials that could harm a disposal. His advice is to look for products specifically formulated for disposal cleaning. InSinkErator’s FAQ also advises against harsh cleaning products, along with fats and oils.
Septic systems
Affresh and Bastion state septic safety on their listings. If you have a septic system and the listing says nothing, check with the maker. We make no promises beyond what each maker says.
How we picked these eight cleaners
We have not used these products ourselves. We looked for named makers, products made specifically for disposals and useful directions. Our search for independent comparisons found mostly affiliate lists with no documented method, so those are not cited here. Most picks rest on maker listings, and we say so. We limited Amazon-first brands, and included one. Drain openers and septic treatments were left out, since Consumer Reports warns against chemical drain cleaners in a disposal.
Disposal cleaning tablets and other questions
How often should I use disposal cleaning tablets?
Makers disagree. Affresh sells 12 tablets as a year’s supply, Glisten and Rejuvenate suggest weekly use, and Plink and Bastion suggest twice a week. Follow the box.
Can I use hot water with a disposal cleaner?
Plink and Bastion mention hot water for their products. InSinkErator tells you to grind food waste with cold water. Follow the cleaner’s box for the cleaning step and use cold water when you grind food.
Can I pour bleach in a garbage disposal?
InSinkErator’s FAQ advises against harsh cleaning products. Consumer Reports’ routine uses a very small amount of bleach, so advice differs. We would skip it, and you should never combine bleach with an acid-based cleaner such as Lemi Shine.
The smell keeps coming back. What now?
Clean the splash guard, run plenty of cold water while grinding, and keep grease out. Consumer Reports notes that the P-trap blocks sewer gases, so a lasting smell may need a plumber. If the unit itself is old, see our garbage disposal guide.
Our final pick for a fresh disposal
Buy Affresh for a monthly routine, and Glisten for a smell that has already set in. For the grease that causes much of the trouble, wipe pans first and wash them with something from our dish soap guide, then scrub the baffle with a tool from our kitchen scrub brush guide.
