A washing machine that still smells after a cycle can make freshly cleaned clothes feel anything but clean, and the endless stream of conflicting advice online does not make the problem any easier to solve.
Here's what to know
In a Reddit thread on r/HomeMaintenance, users compared the methods that had actually helped improve the smell in their washer. One simple fix that drew especially strong support was cleaning the machine with citric acid.
"I feel like ive tried everything and my machine still smells off after a wash," the original poster said. "Looked it up and theres like a million different methods and products and i genuinely dont know whats worth trying. What do you guys actually use that works?"
One of the most specific recommendations was powdered citric acid. A commenter said to use "1/2 cup to a clean cycle" and that it "removed my washer's 'stale water' smell that vinegar wasn't helping with."
Several replies pointed away from the drum alone and toward residue in other parts of the washer.
"Don't use fabric softener," one person advised. "It leaves a greasy residue. Once a month use the tablets to clean. And always leave the door open after each wash."

People also repeatedly mentioned the drain filter as a place odors can start. One commenter said they did not even know their washer had a filter until they later bought a home and a better machine.
More background
A washer can look fine and still hold moisture in less visible spots, including the door seal, the detergent dispenser, and the lower drain area. That lingering dampness can create the musty "stale water" odor described in the thread.
For some owners, the biggest maintenance issue is not the tub itself. Commenters noted that filters can collect dirty water and debris, and that shutting the washer door or detergent dispenser between loads can leave moisture trapped inside.
The discussion also suggested that common household cleaners are not a universal answer. In particular, vinegar did not seem to solve every washer-odor problem people described.
What can be done?
If a washer smell will not go away, homeowners can start by checking the manual for any cleaning steps recommended by the manufacturer. The thread also pointed to a few practical measures: run an empty clean cycle with powdered citric acid, clean the filter, and wipe the door gasket and detergent tray.
Commenters also mentioned skipping fabric softener, which they said can leave behind residue that contributes to repeat odors.
Where can I learn more?
It can be easy to miss areas of a washing machine that might be contributing to lingering odors.
• A simple habit like cleaning the hidden filter can help a washer last longer.
