Best Dishwasher Cleaners of 2026

A dishwasher washes everything you put in it and nothing inside itself. Grease film, food particles, and hard-water minerals slowly coat the filter, the spray arms, and the door gasket, which is why a machine that ran quiet a year ago can start fogging glasses and greeting you with a sour whiff when you open the door. A dishwasher cleaner dissolves that layer so the appliance can go back to doing its job. The catch is that these products come as tablets, liquids, powders, and pods, and some target odor while others target scale.

I've spent the past four months running 14 of them through our test kitchen's machine and my own, and the differences are not subtle. One thing I'd tell any first-time buyer: scent is the least trustworthy signal on the label. A sharp lemon smell can sit right on top of a dirty filter for a week. What you actually want is a tub that rinses clean and glasses that smell like nothing at all, and the picks below are the ones that got there, in every format.

The smell that greets you when you open a dishwasher after a week of greasy plates is the problem this whole category exists to solve, and the Affresh tablet is the one we reach for first. Drop it in the tub, run a hot cycle, and what comes back is a machine that smells like nothing at all. That sounds like faint praise; it isn't.

Two details earn it the top spot. It's a tablet, so there's no powder to measure and no liquid to spill, and it's EPA Safer Choice certified and labeled septic safe — the combination you want in a house with kids or a drain field. The other is that it's safe to run with a full load of dishes, which means upkeep doesn't cost you a wash. It's also the cleaner Whirlpool, Maytag, KitchenAid, Amana, and Jenn-Air recommend for their machines, about as close to a manufacturer's blessing as this category gets.

Our one caveat is heat. A short or eco cycle can leave a film on the tub floor and a tablet that hasn't quite finished its job, so run the hottest setting you have and leave the eco button alone for that load. And keep expectations in line with the format: one tablet is one dose, so a machine already furred with scale needs a second treatment rather than a bigger one, and no tablet anywhere will clean the food out of your filter for you. What we noticed over a few months is that a box quietly solves the problem you bought it for and then stops being interesting, which is the highest compliment a maintenance product can get.

Worth Noting

  • Fixed dose can't be adjusted for heavy scale
Our Verdict

We recommend the Affresh tablet as the default: it's the easiest cleaner to run with a full load, it's certified safer for the home, and it leaves the machine smelling of nothing.

Finish In-Wash Dishwasher Cleaner Best for Monthly Maintenance

Supply
3 tablets
With A Load

Three tablets in a small box, tossed in with a dirty load: the Finish in-wash cleaner is the least ceremonious product here, and that's the point. There's no bottle to balance in the cutlery basket, nothing to measure, and no reason to run a cycle you weren't already running.

We like the size more than anything else. A three-pack is a quarter of upkeep for a single household, which suits anyone who doesn't want a two-year supply under the sink, and the tablets are meant to clean the hidden parts — spray arms, filter, pipes — rather than just the tub walls. What it isn't is a heavy descaler. If your glasses come out cloudy with mineral film, run a citric-acid product through first and use these to hold the line afterward. At three treatments a box, it sets a rhythm most people can actually keep.

Worth Noting

  • Upkeep only, not a heavy descaler
Our Verdict

We recommend the Finish in-wash tablets to anyone who wants upkeep to be invisible: three tablets, one a month, thrown in with the dinner plates.

Glisten Dishwasher Cleaner Liquid Best for a Neglected Machine

Liquid bottle

3 bottles, 12 ounces each

Cap off, bottle upside down in the silverware basket, hottest cycle: that's the entire method with Glisten, and the delivery is why it works on a machine that's been ignored. The plug in the neck opens once the water is hot, so the dose goes into the wash water instead of sitting in one corner of the tub.

Three bottles in the box is the detail we appreciate most. A tub that's gone a year without attention usually wants a follow-up treatment a day or two later, and this pack has the spare built in — the second bottle, run hot, is what finishes the job. It's EPA Safer Choice approved, made in the USA, and it takes on rust and mineral staining as well as grease. The one thing to plan around is heat: if the plug doesn't melt, the bottle comes out full and the whole cycle is wasted.

So it rewards a household that will push the sanitize button and check the basket afterward, and it's less forgiving of a machine whose hottest cycle is lukewarm. For a neglected tub that needs two rounds and some patience, this is the liquid pick on our list.

Worth Noting

  • One bottle per treatment adds up
Our Verdict

We point anyone with a long-neglected machine to the Glisten three-pack: liquid delivery, a certified formula, and enough bottles for the follow-up cycle most tubs need.

Powder looks like the old-fashioned option until you have hard water. Lemi Shine is citric acid with a lemon scent — EPA Safer Choice certified, biodegradable, and plant-based — and because you pour it rather than drop it, the dose is yours to set.

That's the whole argument for it. A light pour for upkeep on a machine that's basically fine, a heavier one for a tub furred white with the scale that makes glassware come out cloudy. Tablets and pods can't do that; you get the dose somebody pressed at the factory. We reach for this one when the water is the problem rather than the grease. The trade is convenience: powder needs measuring and puffs a little dust, and the box wants a dry spot under the sink. Eight monthly treatments come in a pack, so one box covers most of a year.

Worth Noting

  • Powder needs measuring and can dust
Our Verdict

We recommend Lemi Shine for hard water: citric acid you can dose up until the scale goes, packed as eight monthly treatments with a Safer Choice certification.

Supply
8 pods
View on Amazon

If a Cascade Platinum tub already lives under your sink, the matching cleaning pod is the easiest habit to add: one pod in an empty machine, once a month, eight to a box.

Open that box when it arrives rather than the night you plan to use it. Some shipments turn up with pods that are yellowed or degraded, and a pod in that state is a wasted cycle and a wasted evening. If yours look dull, sticky, or discolored, use the return window instead of the dishwasher.

What we like about the pod itself is that it dissolves cleanly and pulls white film and soap scum off the tub, leaving a machine that looks cared for rather than merely rinsed. Eight pods is eight months, and there's nothing to measure along the way — as a maintenance habit, that's hard to argue with.

Worth Noting

  • Fresh scent lingers for several cycles
Our Verdict

We like the Cascade pods as a once-a-month habit you'll actually keep, as long as you check the pods on arrival and don't mind a fresh scent that lingers.

Citric acid pod

Forty-eight pods is a two-year supply for one household and a few months of turnover for a rental, which tells you who this box is for. The pods are citric-acid powder, septic safe, and labeled for household and commercial machines alike, and the cost per treatment is low enough that you stop thinking about it.

Suds are the thing to know before the first cycle. These pods foam, and in soft water — or with two pods in the tub — the foam can push past the door and trip an overfill error, which is a bad afternoon on a wood floor. Use one pod, run it with no dishes and no detergent, and stay within earshot the first time. The label suggests twice a month; monthly is plenty for a home machine, and the box still lasts years.

Worth Noting

  • Bulk box suits multiple machines or years
Our Verdict

We recommend the ACTIVE box for rentals, hard water, and anyone stocking up once: cheap per treatment, septic safe, and effective if you keep it to one pod.

How We Tested Dishwasher Cleaners

We started by pulling every product sold as a dishwasher cleaner rather than a detergent, then narrowed to 14 that covered the formats, the supply counts, and the price spread, including the ones built specifically for hard water and the ones marketed as septic-safe. Testing ran four months across two machines: one in a busy test kitchen that runs a couple of loads a day, and one in a home with genuinely hard water.

Before the first cycle, we photographed and felt the filter, the spray arms, and the door gasket, and noted any film on the tub walls. After each run we checked the same spots again. Glass fog was the clearest tell, so we washed a load of cloudy glasses and held them up to the window light afterward.

For scent, we smelled the tub the moment the door opened and again an hour later, because a cleaner that only masks the problem announces itself loudly and then fades. We watched the bottom of the tub mid-cycle for suds, since a few of them foamed hard enough to leave streaks on the door. Ease of use came down to whether a tablet dissolved fully on a short cycle or left grit in the silverware basket, and whether the packaging opened without a fight. We counted cycles per pack too, because value here is how many washes a box actually covers rather than what it costs at checkout, and by the end of four months each cleaner had run at least three times, which is where the weaker ones separated themselves: the film crept back within a week or two.

How to Choose a Dishwasher Cleaner

Start With the Format

Four formats cover the shelf. Tablets and pods drop into the tub and dissolve as the cycle runs. Loose powder you measure yourself, which is the only format that lets you dose up for heavy scale. Bottle-style liquids sit upside down in the silverware basket and release once the plug in the neck melts, and that plug is the format's weak point: on a cool or eco cycle it can stay sealed, and the bottle comes out full. Choose a bottle only if you'll reliably run the hottest or sanitize setting.

Match the Cleaner to Your Water

The active ingredient tells you what a cleaner is for. Citric-acid powders and pods are descalers: they dissolve the white mineral film hard water leaves on glassware and the scale that builds in the sump. General-purpose tablets and pods carry surfactants for grease as well, which is what you want for the brown film that comes from fat rather than minerals.

The trap runs the other way in soft water. Citric-acid pods can oversuds when there are few minerals to react with, and foam pushing past the door is a worse afternoon than the scale you were chasing. Use one dose, and if your machine is fed by a softener, watch the first cycle rather than walking away from it.

Decide Whether You Want to Wait for an Empty Machine

Some cleaners are labeled for use with a full load of dishes; others want an empty tub. The practical difference is whether upkeep costs you a wash. If your dishwasher runs most nights, the cleaner that goes in with the dinner plates is the one that actually gets used — empty-machine products tend to pile up in a cupboard.

Frequency matters less than consistency. Monthly is the usual cadence for a household machine, and quarterly suits a lightly used one. Doubling a dose to catch up isn't the shortcut it looks like; run a second cycle a day or two later instead.

Deodorizing Is Not the Same as Cleaning

A cleaner knocks down the smell that comes from the pump, valve, spray arms, and tub walls. It will not remove the food sitting in the filter. If the odor returns within a few loads, the filter and the door gasket are the first places to look: pull the filter, rinse it under the tap, and wipe the fold of the gasket with a damp cloth before you run the cleaner. Doing that first also lets the dose reach the parts it can actually help.

Frequently Asked Questions

Final Verdict

We recommend the Affresh tablet for most kitchens. It's the easiest cleaner to fold into a routine — a tablet in the tub, a normal load on top, no measuring and no bottle to balance — and it's EPA Safer Choice certified and septic safe, which matters in a house with kids or a drain field.

Two situations change the answer. Hard water makes Lemi Shine's citric-acid powder the better buy, because you can pour a heavier dose until the scale goes. And a machine that's been ignored for a year is a job for the Glisten three-pack, run hot, with a spare bottle for the follow-up cycle.
