Modern washing machines are great for saving water and energy, but they sometimes leave behind a greasy residue called “biofilm” (nope, it’s not bugs!). Here’s how to keep your machine fresh and your laundry smelling clean.
What causes the greasy smell in my washer?
Lower water usage, lower temperatures, and leftover detergent can lead to a buildup of residue, especially on thick fabrics like jeans and towels. Over time, this buildup can make your clothes smell, even after washing.
How can I clean my washing machine?
Do a hot, empty wash with soda crystals
Once a month, run an empty cycle with half a bag of soda crystals and a liter of boiling water in the drum. Set the machine to the hottest cycle. This will dissolve residue and eliminate odors.
Tips to keep your washer smelling fresh
- Run a hot cycle monthly: Do a “maintenance wash” at high temperature with extra water if available.
- Use the right detergent amount: Avoid using too much detergent, and don’t overload the drum. A hand-width gap should be between the drum and clothes.
- Dry the door seal and detergent drawer: Wipe down the rubber door seal and leave the door slightly open after each wash. Also, rinse and leave the detergent drawer open to dry.
- Skip fabric softener on cotton, silk, and wool: Fabric softener is best for synthetics, as it reduces static. For natural fibers, it creates a coating that limits absorbency.
Pro tip: Dry your clothes as soon as they’re washed to prevent any lingering odors from setting in.
