My front loader had developed that stale, swampy smell that transfers to clean towels, so I ran affresh washing machine cleaner through it and then tested four rival washer cleaners over the following weeks, checking the drum, the door gasket, and how the next loads of laundry actually smelled. A washing machine that cleans your clothes can quietly become the dirtiest appliance in the house, and I wanted to know which cleaner fixed that with the least fuss and the most honest results. Some cleaned well, and one clearly worked harder than the rest.

I picked up Affresh Washing Machine Cleaner because it is the brand my washer's manual names, and I wanted to start with the manufacturer's own recommendation.

I started using Affresh Washing Machine Cleaner when the laundry room itself started smelling like the machine, which was my sign that regular detergent was not reaching the buildup behind the drum.

I bought OxiClean Washing Machine Cleaner with Odor Blasters because the pre-measured pouches looked like the fastest option: tear, pour into the empty drum, run hot water.

The first clean took the sour edge off a machine that had been closed up wet for a vacation week. —Laura Scott
I picked up OxiClean Washing Machine Cleaner with Odor Blasters for the machine at my rental unit, which sees heavy use and little care. The box suggests weekly cycles for three weeks for existing odors, then monthly, and I followed that plan.

4. Washing Machine Cleaner by Tide, Washer Machine Cleaner with Oxi for Front and Top Loader Washer Machines, Deep Cleaning Residue & Odor Eliminator, 5 Month Supply (Packaging May Vary)
I tried Washing Machine Cleaner by Tide because the Oxi plus TAED formula is specifically pitched at hard water homes like mine, where mineral content dulls everything a normal cleaner does. The powder packets activate fast in hot water, faster than tablets in my side by side timing, and they reach the pump and hoses where residue hides. After one cycle the drum looked brighter and the stale detergent smell was gone. —Daniel Wright
I started using Washing Machine Cleaner by Tide when white mineral film started appearing on dark loads, a sign the machine itself was redepositing buildup onto clothes. Two monthly cycles later, that film stopped showing up, which convinced me the hard water claim is more than marketing. The familiar Tide scent left behind is pleasant and mild. Powder can be a little messier than a tablet if you spill it, so pour carefully over the drum. —Ashley Turner
Me and Washing Machine Cleaner by Tide have become a good match for the winter months, when our water is coldest and cleaners usually underperform, because the TAED boost is designed to work even then. Buyers in hard water areas rate it as their fix when tablets disappoint. If your machine's problem is mineral scale and dull, grey looking laundry rather than odor alone, this is the specialist I would start with. —Chris Donovan

No powder to spill, no pouch to tear, just one tablet in the empty drum on a hot cycle. They handled the general freshening job well in both our machines.

Why Affresh Washing Machine Cleaner Is Necessary
A washing machine is a warm, wet, dark box that you regularly fill with dirty clothes, detergent, and fabric softener, and then close up. Residue from all of that builds up behind the drum, in the pump, in the hoses, and around the door gasket, where normal wash cycles never scrub. That buildup is what makes clean laundry come out smelling stale. A dedicated washer cleaner is formulated to dissolve and flush out exactly that hidden layer, which plain detergent cannot do.
Regular machine cleaning also protects the appliance itself. Scale and residue make the motor and pump work harder, dull the drum, and can leave grey film on dark clothes as the machine redeposits its own dirt onto your laundry. Manufacturers recommend a monthly cleaning cycle for a reason, and front loaders with their watertight gaskets need it most of all. Ten minutes of prevention each month is far cheaper than a service call or a machine that never smells clean again.
Finally, a clean machine simply washes better. Detergent works as designed when it is not fighting a layer of old residue, water flows freely, and the scent you paid for in your detergent is the scent your clothes carry. In my testing, the loads after a proper machine clean were noticeably fresher without changing detergent at all. If your laundry smells fine going in and stale coming out, the machine is the problem, and this is the fix.
My Buying Guides on Affresh Washing Machine Cleaner
Why I Looked for Affresh Washing Machine Cleaner
My towels started smelling musty straight out of the wash, and the laundry room had a swampy note every time I opened the machine door.
I tested the manufacturer recommended cleaner first, then four rivals, judging each on the drum, the gasket, and how the next real loads smelled.
What I Check Before Buying
I check compatibility first: the cleaner must suit front load, top load, and HE machines, and be septic safe if your home runs on a septic system.
Then I look at format and schedule. Monthly tablets are easiest to stick with, powders activate fastest, and descaler formulas matter most in hard water areas.
My Preference for Tablets or Powder Cleaners
For monthly maintenance I prefer tablets, because there is nothing to measure or spill and the slow dissolve keeps cleaner working through the whole cycle.
For a machine that already smells bad, I start with a powder or a repeat tablet plan for the first month, then switch back to simple monthly tablets.
What I Look for in Quality
A quality cleaner reaches beyond the visible drum: pumps, hoses, and the gasket area are where odor actually lives, so I judge results by smell a week later.
Certifications help too. EPA Safer Choice and septic safe labels tell me the formula is effective without being harsh on the machine or the plumbing.
How I Compare Prices
I compare cost per month of protection, not per box. A 24 tablet box that covers a year or two usually beats small boxes bought over and over.
I also count how many cycles a neglected machine needs. A cleaner that fixes the smell in one cycle is cheaper than a bargain one that takes four.
My Tips for Choosing the Right One
Match the cleaner to your problem: odor calls for an odor focused formula, white scale calls for a descaler, and general upkeep calls for a simple monthly tablet.
Whatever you buy, wipe the gasket and leave the door ajar after the cleaning cycle. The cleaner loosens the grime; those two habits stop it coming back.
Final Thoughts
Affresh Washing Machine Cleaner is the cleaner I now use monthly, because it is the manufacturer recommended option, it is certified and septic safe, and it simply ended the musty towel problem in my house. ACTIVE is the better buy for hard water scale and a year of supply in one box, OxiClean is the fastest small box fix, Tide is the hard water specialist, and True Fresh is the easiest maintenance tablet for family homes.
If your laundry smells stale no matter what detergent you use, do not buy another detergent. Run one of these cleaners on the hottest empty cycle, wipe the gasket, and smell the next load. That single test will tell you your machine was the problem all along, and a monthly tablet from this list will keep it from ever becoming the problem again.
