Why You Need to Clean Your Washing Machine
It might seem counterintuitive, but washing machines get dirty with regular use. Understanding why helps you appreciate the importance of routine cleaning.
Detergent & Softener Residue
Excess detergent & fabric softener don’t fully rinse away. They accumulate in the drum, door gasket, dispensers, & internal components, creating a film that traps dirt & encourages bacterial growth. High-efficiency (HE) washers are particularly susceptible because they use less water for rinsing.
Mold & Mildew
The warm, moist environment inside a closed washing machine is ideal for mold & mildew growth. Front-load washers are especially prone to this problem around the rubber door gasket, where water collects in folds & crevices. This is a primary cause of the musty smell many washer owners experience.
Bacteria & Biofilm
Research shows that washing machines harbor significant bacterial populations, including E. coli & Staphylococcus. Cold-water washing cycles (common with modern energy-efficient machines) don’t reach temperatures high enough to kill these organisms. Regular cleaning with an effective washer cleaner eliminates bacterial biofilm.
Hard Water Deposits
Mineral deposits from hard water build up on internal components, reducing efficiency & potentially damaging the machine over time. Calcium & lime scale restrict water flow, reduce heating element efficiency, & can cause premature component failure.

Best Cleaners for Front Load Washers
Front-load washers present unique cleaning challenges due to their rubber door gasket & horizontal drum orientation that allows water to pool.
Top Pick: Affresh
Affresh tablets are specifically designed to work inside the drum during a clean cycle, dissolving slowly to penetrate & remove residue, odor-causing buildup, & mildew. They’re recommended by most major washer manufacturers including Whirlpool, Maytag, & Samsung. For front-loaders, Affresh is our top recommendation due to its proven effectiveness against gasket mold.
Gasket Cleaning
The rubber door gasket on front-load washers requires special attention. Pull back the gasket folds & wipe with a solution of equal parts water & white vinegar. For visible mold, apply a paste of baking soda & water, let it sit for 15 minutes, then scrub with an old toothbrush. For stubborn mold spray products can also be effective on gasket mold.
Prevention Tips
Leave the door ajar after each wash to allow air circulation & drying. Wipe the gasket dry after every use. Use only HE detergent in the recommended amount — more detergent doesn’t mean cleaner clothes, just more residue.
Best Cleaners for Top Load Washers
Top-load washers are generally less prone to mold issues but still accumulate detergent residue, minerals, & bacteria over time.
Top Pick: Tide Washing Machine Cleaner
Tide’s oxygenated bleach formula works exceptionally well in top-load washers, where the larger water volume helps distribute the cleaning agent throughout the entire tub. It removes residue from the drum, agitator, & internal plumbing effectively.
Agitator Cleaning
If your top-loader has a traditional agitator, remove the fabric softener dispenser cap (if applicable) & clean underneath where buildup commonly occurs. Soak removable agitator parts in a vinegar solution for 30 minutes, then scrub & rinse before replacing.
Types of Washing Machine Cleaners
| Type | How It Works | Pros | Cons | Best For |
|---|---|---|---|---|
| Tablets | Dissolve slowly during cycle | Precise dosing, no mess | Pricier per use | Regular monthly cleaning |
| Powder pouches | Dissolve quickly in water | Effective, affordable | Can clump if wet | Deep cleaning sessions |
| Liquid | Pour into drum or dispenser | Versatile, can spot-treat | Easy to over/under-dose | Targeted cleaning & gaskets |
| Spray | Apply to surfaces directly | Precise application | Not for internal cleaning | Gaskets, dispensers, exterior |
DIY Washing Machine Cleaning Solutions
Effective washing machine cleaning doesn’t always require specialty products. Several household items work remarkably well.
White Vinegar & Baking Soda Method
This is the most popular & effective DIY cleaning method. Pour 2 cups of white vinegar into the detergent dispenser & run a hot water cycle. When the cycle is halfway done, pause it & add 1/2 cup of baking soda directly to the drum. Complete the cycle, then run a final rinse. The vinegar dissolves mineral deposits & kills bacteria, while baking soda deodorizes & removes residue.
Citric Acid Method
Citric acid is particularly effective against hard water deposits & lime scale. Add 1/2 cup of citric acid powder directly to the drum & run a hot cycle. This method is gentler on rubber gaskets than bleach-based alternatives while being excellent at dissolving mineral buildup.
Bleach Method
For heavy mold & mildew issues, add 1/2 cup of chlorine bleach to the bleach dispenser & run a hot cycle. This is the most aggressive cleaning method & should be used sparingly (no more than once every 2-3 months) as bleach can degrade rubber components over time. Never mix bleach with vinegar — this produces toxic chlorine gas.
Hydrogen Peroxide Method
A gentler alternative to bleach, hydrogen peroxide (3% solution) effectively kills mold & bacteria without the harsh effects on rubber seals. Add 2 cups to the drum & run a hot cycle. It’s particularly good for front-load washers where gasket integrity is crucial.
How to Clean Your Washing Machine
Step-by-Step Deep Cleaning Process
Step 1 — Clean the dispensers: Remove detergent, softener, & bleach dispensers (if removable). Soak them in warm, soapy water for 15 minutes. Scrub with a small brush to remove buildup, rinse, & replace.
Step 2 — Clean the gasket (front load): Pull back the rubber door gasket & wipe out any debris, hair, or residue. Spray with a vinegar solution or washing machine cleaner & scrub with a cloth or toothbrush.
Step 3 — Run the cleaning cycle: Add your chosen washing machine cleaner to the drum (or dispenser, per product instructions). Select the “Clean Washer” cycle if available, or use the hottest, longest cycle with an extra rinse. Run the cycle empty — no clothes.
Step 4 — Wipe the interior: After the cycle completes, wipe down the inside of the drum, the door glass, & the opening with a clean microfiber cloth.
Step 5 — Clean the exterior: Wipe down the control panel, exterior surfaces, & the door handle with an all-purpose cleaner. Clean the drain filter (front-loaders) according to your owner’s manual.
Step 6 — Leave the door open: Allow the machine to air dry completely by leaving the door open for several hours after cleaning.
Cleaning Schedule & Prevention
| Task | Frequency | Time Required |
|---|---|---|
| Leave door open after use | After every wash | 0 minutes |
| Wipe gasket dry (front load) | After every wash | 1 minute |
| Run cleaning cycle with cleaner | Monthly | 5 min (hands-on) |
| Clean dispensers | Monthly | 10 minutes |
| Deep clean (all components) | Every 3 months | 30-45 minutes |
| Clean drain filter (front load) | Every 3 months | 10 minutes |
| Inspect & clean hoses | Annually | 20 minutes |
Prevention Best Practices
Use the correct amount of HE detergent — more isn’t better. Switch to liquid detergent if you frequently experience residue buildup. Run a hot water cycle at least once per week, even if most loads use cold water. Remove wet clothes promptly after the cycle ends. Consider leaving the detergent dispenser drawer open along with the door.

Frequently Asked Questions
How often should you clean your washing machine?
Run a cleaning cycle with a washing machine cleaner once per month for optimal performance. If you primarily wash in cold water, use fabric softener frequently, or notice any musty odors, increase to twice monthly. Front-load washers generally require more frequent cleaning than top-loaders.
Can you use bleach to clean a washing machine?
Yes, chlorine bleach can be used to clean a washing machine, but it should be used sparingly (every 2-3 months at most). Add 1/2 cup to the bleach dispenser & run a hot cycle. Bleach is highly effective against mold & bacteria but can degrade rubber gaskets over time. Never combine bleach with vinegar or ammonia.
Why does my washing machine smell?
Musty smells are typically caused by mold & mildew growth inside the machine, particularly around the door gasket (front-loaders) or under the agitator (top-loaders). Contributing factors include using too much detergent, washing exclusively in cold water, & keeping the door closed between loads. Regular cleaning with a quality washer cleaner eliminates these odors.
Is vinegar safe for washing machines?
White distilled vinegar is generally safe for washing machines when used monthly. It effectively dissolves mineral deposits, kills bacteria, & deodorizes without harsh chemicals. However, excessive or daily use may gradually degrade rubber seals & gaskets. Using vinegar once or twice monthly is a safe, effective cleaning practice.
What is the best washing machine cleaner for front loaders?
Affresh Washing Machine Cleaner tablets are the top choice for front-load washers. They’re recommended by major manufacturers, effectively combat gasket mold & mildew, & dissolve slowly for thorough drum cleaning. Pair with manual gasket wiping for the best results.
Do washing machine cleaning tablets really work?
Yes, quality washing machine cleaning tablets from brands like Affresh & Eco-Gals are highly effective. They dissolve slowly during the cleaning cycle, allowing active ingredients to penetrate & remove buildup throughout the drum & internal components. For best results, use them as directed on a monthly schedule.
Can a dirty washing machine make you sick?
While rare, bacteria from dirty washing machines can potentially cause skin irritation, allergic reactions, or infections — particularly in people with compromised immune systems. Research has found E. coli, Staphylococcus, & other pathogens in uncleaned washers. Regular cleaning significantly reduces this risk.
