Washing Machine Cleaning & Care (Complete Guide)
Share
Clean your washing machine once a month with a dedicated cleaner tablet and leave the door ajar between loads — that prevents the musty smell, residue, and mildew that build up in the drum, gasket, and detergent drawer. Washers are damp, enclosed, and full of organic residue from clothes, so they're prime territory for odor and biofilm. This guide covers the why, the step-by-step, the product choices, and a schedule that keeps your machine — and your laundry — fresh.
Why Washers Get Smelly
Every load leaves behind detergent film, fabric softener, body oils, and lint. In a sealed, humid drum those accumulate into a slimy biofilm on the gasket and a stale smell that transfers to clothes. Front-loaders are especially prone because the rubber gasket stays damp. The fix is regular cleaning plus airflow.
Step-by-Step: Clean Your Washer
- Run an empty hot cycle with a cleaner tablet. Drop a washing machine cleaner tablet in the empty drum and run the longest hot cycle to dissolve residue.
- Wipe the gasket and drawer. Pull back the rubber seal and wipe the folds with a cloth; remove and rinse the detergent drawer.
- Clean the filter. If your model has a lint/pump filter, rinse it under running water.
- Leave the door ajar. Airflow is the single best mildew preventer between loads.
- Wipe the exterior. A plant-based surface cleaner keeps the top and controls fresh.

Mistakes to Avoid
- Closing the door after every wash. Trapped moisture is what grows mildew — leave it ajar.
- Overusing detergent. More soap means more residue; use the recommended amount.
- Ignoring the gasket. Wipe the folds weekly on front-loaders.
- Skipping the filter. A clogged pump filter traps odor and lint.
Frequently Asked Questions
How often should I clean my washing machine?
Once a month for most homes; every 2–3 weeks if you wash pets' bedding or run many loads. Our smelly-machine guide has the step-by-step.
Why does my washer smell like mildew?
Trapped moisture in the gasket and residue buildup. Run a hot tablet cycle, wipe the seal, and leave the door open to dry.
Are washer cleaner tablets safe for septic and pets?
Plant-based tablets are formulated to be septic-safe and low-residue. Keep them stored away from pets, and see our pet-safe home cleaning guide.
Do I need a special tablet for pet hair?
The Pet Owner pack targets hair and odor buildup common in pet households — a good call if you wash pet beds regularly.
Front-load or top-load — different cleaning?
The principles are the same; front-loaders just need extra gasket attention because the seal stays damp.
Can I use the same cleaner for the washer and toilet?
Use dedicated products: washer tablets for the machine, a toilet cleaner for the bowl. Cross-using isn't necessary and can be messy.
How do I keep laundry itself smelling fresh?
Clean the machine monthly and add a lavender scent booster at wash — see our laundry freshness guide (coming in this series).
