That sour, musty smell hitting you as you open the dishwasher door is a sign of trapped food, grease, and mineral buildup hiding in the nooks and crannies. A dedicated cleaner strips out the grime that regular detergent leaves behind, so your machine runs fresh and your dishes don’t pick up any leftover odors.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Your dishwasher smells bad because food residue and grease build up inside. The right dishwasher cleaner for smell breaks down that gunk so your kitchen smells clean again, not like a dirty machine.
Our Picks at a Glance
How To Choose The Best Dishwasher Cleaner For Smell
The right cleaner depends on what is causing your odor — trapped grease, mineral scale, or a biofilm that regular detergent misses. You want a formula that targets the actual source, not just masks it with a fragrance.
Active Ingredient — The Core of Odor Removal
Enzymatic formulas break down food-based gunk and are typically safe for both dishwashers and washing machines. Citric acid tablets target hard-water limescale and the odors trapped in that layer. Oxygen bleach (sodium percarbonate) releases active oxygen to cut through grease and sanitize deep inside the jets and filters. Choose based on whether your smell is from food residue or mineral buildup.
Frequency and Supply
A single-use pack is fine for a one-time deep clean, but a recurring stink needs monthly maintenance. A 24-pack or 26-pack gives you a full year of monthly cleanings without reordering. Some products work alongside your regular detergent in a normal cycle, which is more convenient than running an empty hot cycle every time.
Compatibility and Safety
Almost all modern cleaners are septic safe and work with stainless steel or plastic interiors. But if you have a specific brand like Bosch, KitchenAid, or Miele, check whether the cleaner is formulated to protect rubber seals and gaskets — some heavy-duty formulas can degrade door seals over time if used too often.

In-Depth Reviews
1. Plink Washer and Dishwasher Freshener and Cleaner
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
The simple tablet that keeps your dishwasher smelling fresh between washes.
This is the tightest all-around odor-fighter on the list. It uses an innovative enzymatic formula with powerful effervescent action to break down the gunk that creates sour smells, and it works in both a dishwasher and a clothes washer without any phosphates or bleach. The 8 tablets come as two packs of 4, so you can stash one in the laundry room.
What wins people over is how reliably it prevents that sour dishrag smell — the most-discussed point across the reviews is its cleaning performance. The lemon scent leaves the room smelling fresh, and owners consistently call it easy: you just place a tablet in the dishwasher base, load dishes as usual, add detergent, and run a regular cycle. A short 7.91 x 5.08 x 1.46-inch package also makes it the largest tablet box by dimensions, at 7.91 x 5.08 x 1.46 inches versus The Clean People’s 4.37 x 3.07 x 2.44 inches, though the tablets themselves dissolve fast.
The crowd favorite: The cleaning performance is what owners rave about most — that fresh, non-residue result after every cycle — and the fragrance is a close second.
A fair trade-off: You get only 8 tablets total (two packs of 4), so for monthly maintenance that is only about 8 months of supply. If you want a full year of cleanings in one box, the 24-count options below stretch further.
Grab it for: Anyone who wants a deodorizer that works inside a regular dish load without extra steps — and works in the laundry washer too.
Better to pick a different box if: You need a full 12-month supply in a single purchase rather than a smaller pack.
2. The Clean People Dishwasher Cleaner Tablets
A clean-ingredient tablet that tackles limescale, grease, and odors without harsh chemicals.
This cleaner uses clean ingredients — no phosphates, parabens, phthalates, chlorine bleach, artificial dyes, or ammonia — to penetrate deep inside machine components and wash away grime and scale. It is designed to be septic safe and works with all major dishwasher brands. The 6-count pack is modest, but the citrus scent is a consistent highlight in the reviews.
The cleaning performance and residue removal dominate the feedback — owners point out that dishes come out clean and shiny “without adopting residue” as one put it. The 5.93-ounce package is notably lighter than the Sudstainables 24-pack (which is 8.68 ounces), and the tablets are compact enough to share a drawer with detergent. A few owners found them effective enough to cut a tablet in half for lighter maintenance.
The edge: The residue-free finish matters — buyers report it removes mineral buildup without leaving a sticky film, a common gripe with some other cleaners.
Choose this for: A low-chemical, residue-free clean that targets limescale and leaves a fresh citrus scent behind.
Keep looking if: You want a bulk pack — 6 tablets covers only half a year of monthly cleaning.
3. FEBU Dishwasher Cleaner Tablets, 24 Pack
A full year of deep-cleaning tablets that use natural ingredients to eliminate food odors and grease.
FEBU combines citric acid, enzymes, and sodium percarbonate — a potent natural trio — to clear out limescale, hard water stains, grease, and food buildup. The formula targets odor-causing food particles directly, and the result is a fragrance-free, neutral-smelling machine rather than a scented cover-up. The 24-pack covers a full year of bi-weekly maintenance.
Owners mention it leaves no scent at all — just clean. The package measures 6.81 x 5.83 x 2.28 inches and weighs 11.36 ounces. One reviewer says: “Took the stink out of our dishwasher and off dishes.” The unscented formula uses active oxygen from sodium percarbonate (a natural bleaching agent) to sanitize without artificial fragrance, so it tackles the smell at the source rather than covering it up.
Year-round coverage: At 24 tablets, it is a true monthly schedule — and the biodegradable, plastic-free packaging is a genuine eco plus.
Reach for this if: You want a heavy-duty, unscented cleaner that tackles stubborn odors without covering them up — and you want a full year’s supply.
Look elsewhere if: You prefer a scented finish; this leaves the machine smelling neutral, not lemony.
4. Miele DishClean Dishwasher Cleaner
The brand-specific cleaner that thoroughly strips limescale and odors while protecting door seals.
Miele formulated this waxy solid cleaner to specifically target odors, limescale residue, and food buildup, while also maintaining the elasticity of door seals to prevent leaks. The single 5.6-ounce bottle is enough for 4-5 applications per year — a light maintenance schedule compared to monthly tablets. It works with all dishwashers, not just Miele models.
The cleaning performance is the top praise — it removes hard water stains and leaves the interior looking like new. Owners call it effective but note the price is high for what you get. “I do think it cleans better than the other brands,” one owner notes, while acknowledging the cost. At 6 x 6 x 12 inches, the bottle is substantial, but the real spec to note is the low annual frequency: 4-5 uses per year is a gentler schedule than monthly deep-cleaning tablets.
The crowd favorite: Cleaning performance edges out everything else — the limescale removal is what buyers consistently praise.
Pick this if: You own a Miele or want a premium formula that protects seal elasticity and requires only a few uses per year.
skip it if: You need a bulk supply or a budget-friendly monthly option — this is a pricier per-use choice.
5. MIGHTY CLEAN Dishwasher Cleaner and Deodorizer 24 Pack
The 24-pack that deep-cleans hidden components and eliminates odor-causing residue for a full year.
This cleaner removes limescale, grease, and food residue from hidden parts, and it works with all dishwasher brands — including stainless steel tub units. The deep-clean formula targets odor-causing buildup in filters and spray arms, leaving the machine sanitized and smelling fresh. At 24 tablets, it is a straightforward one-year supply for monthly maintenance.
Effectiveness is the most-praised aspect across the reviews. One owner with an 11-year old dishwasher found that a single tablet restored it to like-new condition. The package dimensions measure 7.2 x 6.54 x 0.75 inches and it weighs 11.36 ounces — the same weight as FEBU’s 24-pack, suggesting a similar tablet size. A handful of owners mention the value for money is mixed, but the fragrance and cleanliness scores are consistently high.
The standout: The highest count of effectiveness mentions in this whole list — owners are clear that this one works.
Great for: A straightforward monthly schedule that keeps a smelly dishwasher fresh without any extra steps.
One check: A few owners considered the value mixed — not a dealbreaker, but note if budget is tight.
6. Freshero Dishwasher Cleaner and Deodorizer Tablets 26 Pack
The 26-tablet bulk pack that is compatible with Bosch, LG, Samsung, Whirlpool, and more.
Freshero markets its advanced deep-descaling formula around brand compatibility — it explicitly works with residential and commercial machines from Bosch, Frigidaire, LG, Samsung, Whirlpool, KitchenAid, Kenmore, and Maytag. The citric-acid-based tablet dissolves in a hot, empty cycle to release a cleansing foam that reaches every corner. At 26 tablets, you get two extra cleanings beyond a 24-pack, for a full year of bi-monthly maintenance.
Cleaning performance and odor removal are the top praise points. Customers note it eliminates musty odors and visible buildup on door seals and spray arms in a single cycle. One note: the package dimensions are 8.23 x 7.13 x 0.75 inches, so it has a wider footprint than some other 24-packs. The unscented version leaves a clean, non-overpowering finish, though a few owners note that stubborn scaling may need two cycles.
Owners love: The odor removal is a standout — reviewers point out it wiped out long-standing smells that other products didn’t touch.
Reach for it if: You want a generous 26-count box that is explicitly compatible with most major dishwasher brands.
Think twice if: You prefer a scented finish — this is unscented, and it may not fully eliminate heavy limescale on the first pass.
7. Sudstainables Dishwasher Cleaner and Deodorizer Tablets, 24 Pack
The budget-friendly 24-pack that powers through grease and grime for a full year of cleanings.
Each tablet targets spray arms, filters, and hidden components to improve dishwasher performance. It is designed for monthly deep cleaning and works with all major brands, including stainless steel or plastic interiors. Drop one tablet into the detergent tray and run a normal hot cycle alongside your regular detergent — no extra steps.
The cleansing performance gets the most praise — shoppers say cleaner dishes and a better-smelling machine. At 8.68 ounces versus The Clean People’s 5.93 ounces, the Sudstainables pack is the heavier option, which makes sense given the 24 tablets inside. A useful detail: buyers report that using two tablets at once can cause sudsing and a dishwasher error — the instructions say one per cycle, and that is the right dose. The filter still needs manual cleaning, but the deodorizing effect is real.
The feedback: Value for money is mixed — some owners find it a great deal for 24 tablets, while a few wish it had a stronger scent or a more powerful descaling action.
Choose this for: A no-fuss, low-cost monthly maintenance pack that fits any dishwasher and leaves it smelling fresh.
A fair caveat: One tablet per cycle only — doubling up causes sudsing. And it works best alongside manual filter cleaning.
8. Excellent Elements Sodium Percarbonate, 5 lbs
The pure oxygen bleach powder that handles dishwasher odors and a hundred other cleaning jobs.
This is not a tablet — it is 5 pounds of pure sodium percarbonate (99.9% pure), a versatile oxygen bleach that releases active hydrogen peroxide when mixed with water. For the dishwasher, a scoop cuts through grease and grime, removes hard water stains and limescale, and clears out jets, tubes, and filters. It also works as a laundry booster, a carpet cleaner, and an all-purpose stain remover around the house.
Owners consistently praise the cleaning performance — it whitens without yellowing, removes odors without adding any fragrance, and a tiny teaspoon per load goes a long way. The 5-pound bag is packaged in a resealable metallized pouch measuring 10 x 7.24 x 6.34 inches and weighing 5 pounds. For context, this is far more product than any tablet-based cleaner, and owners mention it replaces multiple bottles of specialized cleaners. The cleaning performance across laundry and dishwasher is the most-discussed aspect.
The real scoop: The pure, filler-free formula means a small amount works hard — owners say it outperforms OxiClean because there are no bulking agents.
Grab this for: A multi-surface, fragrance-free cleaning powder that handles dishwasher odors plus laundry, sinks, tubs, and carpets — all from one bag.
Not for you if: You want a ready-to-drop tablet with a pleasant scent. This is a pure chemical powder that requires measuring.
Understanding the Specs
Active Ingredient — What Actually Kills the Smell
The ingredient that does the real work matters more than the brand name. Enzymatic formulas break down food proteins that cause sour smells — good for regular maintenance if your odor comes from leftover food. Citric acid targets the mineral scale that often traps and holds odors, so if your dishwasher has visible white buildup, a citric-acid-based cleaner is the right choice. Oxygen bleach (sodium percarbonate) releases active oxygen to sanitize deep inside the jets and filters, and it is the most versatile option — it works on grease, food residue, and biofilm without adding any artificial fragrance. Knowing which ingredient matches your smell’s root cause helps you avoid products that just mask the odor.
Supply Count — How Many Cleanings You Are Really Buying
A single-use tablet is a one-time deep clean, but treating a persistent smell needs regular monthly or bi-monthly maintenance. A 24-tablet pack covers a full year of monthly use; a 26-tablet pack gives you two extra cleanings. The number of tablets in the box directly affects how consistently you keep the odor gone — buying the smallest pack and forgetting to reorder is exactly how the sour smell creeps back. Packs like Plink’s 8-tablet set are great for starting fresh, but bulk packs like the 24-count options from FEBU, MIGHTY CLEAN, and Freshero are designed to keep the smell gone all year.

Final Thoughts: The Verdict
For most people, the dishwasher cleaner for smell winner is the Plink Freshener and Cleaner. It uses enzymes (natural proteins that eat grease) to clean during a regular dish load, and it also works in a clothes washer — so one product handles two appliances. If you want a full year of bulk tablets in a single box, grab the FEBU 24 Pack for its heavy-duty, unscented natural formula. And for multi-surface use that extends far beyond the dishwasher, the Excellent Elements Sodium Percarbonate is the versatile powerhouse to reach for.
