OxiClean's Washing Machine Cleaner with Odor Blasters will help keep your laundry smelling fresh by removing odor-causing buildup.
Why we like it
If you've ever taken your clean laundry out of the washing machine only to find that it still doesn't smell very fresh, a dirty washing machine could be the culprit. This OxiClean washing machine cleaner is specifically designed to breakdown the buildup that causes musty odors in the washing machine, and it makes good on its promise.
While it has anti-microbial properties thanks to its active ingredients (sodium percarbonate and disodium carbonate), it's still septic-system safe when used as directed.
Finally, this product is added-fragrance free, so is great for those with skin sensitivities, and it doesn't leave behind a strong smell.
How to use it
The cleaner comes in powder form in a small packet. It's easy to use (and you only need to do it once a month-ish). Simply add the contents of the packet to your washer drum and run the clean cycle (or if your machine doesn't have a pre-programmed clean cycle, run a normal wash cycle with hot water).
Do not add laundry or other detergent during the clean cycle. When the cycle is done, wipe the drum, door, rubber gaskets and seals clean of any residue. Then, leave the door open so the machine can air out and dry.
This is a great maintenance cleaner, especially if you have a front-loader that tends to get that signature mildew smell, but if you're dealing with a strong odor (for example, if you left your wet clothes in the washing machine for a few days), you'll need to use one pouch per week for three weeks for the best results.
The Affresh Washing Machine Cleaner is a similar product to the OxiClean version. They have similar active ingredients (the Affresh cleaner users sodium carbonate, OxiClean uses sodium percarobonate), which both create an effervescent cleaning foam, except the Affresh cleaner comes in tab form. Like the OxiClean cleaner, Affresh's washing machine cleaner has rave reviews from around the internet.
Why we like it
This product is awesome for getting rid of everyday mold and mildew smells that tend to build up when you leave the washing machine door closed for just a little bit too long. It also has a light, lemon-y scent that's pleasant but not overpowering and doesn't linger for multiple wash cycles (something we've found with a number of other washing machine cleaner brands).
Note that some reviewers say the tablet doesn't full dissolve in a single wash cycle (choosing a hot water setting should help, though). We haven't experienced this when we tried it, but it's why this cleaner was slightly nudged out by the OxiClean version, since the powder formula completely dissolves every time.
How to use it
Simply pop the tab into your machine's drum, whether it's a front or top-loader, and run a cleaning cycle or normal wash cycle on hot. Then, wipe the inside of the machine down when the cycle is done.
For best results use once a month in the washing machine on its own and let the formula reach hidden areas, killing bacteria and getting rid of any bad odors to leave your machine – and laundry - smelling fresh.
The Glisten liquid washing machine cleaner removes mineral and detergent build-up along with mildew and odors.
Why we like it
If you live in an area with hard water, mineral buildup or limescale can shorten the life of your washing machine. This cleaner tackles both mineral residue, as well as odor causing buildup.
Many reviewers also noted that this cleaner came recommended to them from service technicians or friends who'd used it with great results.
How to use it
To start, pour the product on a clean cloth and wipe out the machine's rubber seals or any hard-to-reach areas where buildup has accumulated. Then, if you own a front-loader, pour a half-a-cup of the cleaner into your machine's detergent dispenser, or if you own a top-loader, pour it straight into the drum (like all washing machine cleaners, do not add clothes or detergent when cleaning your machine). Then, run the machine on a clean cycle or normal cycle using the hot water setting. It's recommended to use this cleaner monthly.
A fantastic preventative solution for new washers, especially if you prefer using low temperature wash cycles that don’t dissolve detergent as easily as a hot wash, which in turn leaves a residue behind. It's also a great maintenance cleaner for washers that take a lot of wear and tear thanks to heavily soiled uniforms, daily loads of kids clothing, hard water, etc.
If you're looking for a value product that gets results, check out the Hiwill Washing Machine Cleaner. It's a generic cleaner that's available only on Amazon, but reviewers love it for its efficacy and comparatively low price.
Why we like it
For one, it's a budget-friendly pick. The tablets comes in a large 32-pack, and it's recommended you use two or three tabs per cleaning. If you only need two, one box of cleaner will last you more than a year and cost just $1.37 per cleaning. The manufacturer also features regular coupons on Amazon (we recently saw one for 30 percent off) so the cost can get even lower.
It also claims to tackle everything from mildew and mites, to rust and grease. Plus, it's unscented, which is a plus for anyone with sensitive skin or who doesn't use fragranced products.
How to use it
This product requires a slightly more involved approach that's designed to help deep clean your machine. After you add the tabs to your washer and start the cycle, it's recommended that you pause the washer when the water level is at it's highest point so the cleaner can soak for two-to-three hours.
After soaking, resume the wash cycle and let it complete as usual.
An excellent choice for Amazon Prime members looking for a value product and a deep clean.
The Eco-Gals Eco Swirlz Washing Machine Cleaner is designed to clean both the drum and drainage system of your washing machine with eco-friendly ingredients.
Why we like it:
This cleaner uses a similar active ingredient to the OxiClean and Affresh cleaners (sodium percarbonate), which is an eco-friendly compound. But, the Eco-Gals product contains few other ingredients, and all of them are earth-friendly. We double checked them on the Environmental Working Group website's to be sure.
Besides being green, this product works like a charm, too.
How to use it
Like most of the other cleaners on this list, you simply add the product to your washer drum and run a hot wash or clean cycle. The only difference with this one is that you have to add two tabs each time you clean, instead of just one.
This is a great pick for those looking for an environmentally-friendly product that'll keep their machine clean.

How to buy the best washing machine cleaner
By keeping the inside of the washing machine clean, you’ll benefit from an appliance that won’t break down every few years or need a new part, which in turn saves you money and hassle in the long term. Here's what to look for in a good washing machine cleaner.
Does it tackle buildup?
In order to keep your washing machine working properly, it’s important to clean the inside regularly. Not only does this deal with any unpleasant odors resulting from moisture, mold and mildew, but it will also help prevent detergent residue and mineral build-up, the enemy of any appliance that uses water, especially if you live in a hard water area.
Does it tackle odors?
A good washing machine cleaner will tackle odors inside the appliance caused by soap scum, grease and grime from clothes, which will in turn leave your laundry smelling fresh.
Does it kill germs?
Look for a cleaner that doubles up, removing stinky odors as well as descaling, cleaning and helping to protect plastic inner workings and the drum itself makes sense. But some solutions are antimicrobial, too, killing germs at the same time, while others can also be used in dishwashers.
Alternatives to washing machine cleaner
All of the washing machine cleaners on our list will do a good job of cleaning your appliances. Having said that, there's plenty of room to experiment with DIY washing machine cleaners. Our top picks for this task are baking soda and dishwasher tablets. Simply put either (or both!) into your washing machine tray and run your machine on the hottest cycle. If you already own a dishwasher, that's one less product you need to buy.
