How to Clean a Washing Machine
Washing machines get dirty — soap scum, mineral deposits from Toronto's tap water, fabric softener residue, and mould from moisture left in the drum and gasket combine to produce the musty smell that transfers to your clothes. Here's how to clean both front-load and top-load machines.
Front-Load Washing Machines
Front-loaders are more prone to mould because water pools inside the rubber door gasket after each use. This is the number one complaint about front-loaders in Toronto homes.
Monthly Cleaning Cycle
- Remove any clothing from the drum
- Add 2 tablespoons of baking soda to the drum directly (not the dispenser)
- Add 2 cups of white vinegar to the detergent dispenser
- Run on the hottest available cycle, longest duration — usually "Cotton" or "Heavy Duty"
- After the cycle completes, leave the door open for 30 minutes to air dry
Alternatively: use a commercial washing machine cleaner tablet (Affresh is widely available at Canadian Tire) in the drum — these are specifically formulated to break down biofilm and mineral deposits.
Rubber Door Gasket
This is where mould actually grows. After every wash:
- Wipe inside the gasket folds with a dry cloth to remove standing water
- Leave the door slightly ajar after each load to allow drying
For existing mould in the gasket: spray the inside of the gasket with a 1:10 bleach-water solution. Leave 5 minutes. Scrub with an old toothbrush inside all the folds. Wipe clean and dry completely. Run an empty hot cycle afterward.
Detergent Dispenser
Remove the dispenser drawer if possible and wash it in warm soapy water — detergent and softener residue build up and become mouldy here. Wipe inside the dispenser housing with a damp cloth.
Top-Load Washing Machines
Top-loaders are less prone to gasket mould but accumulate soap and mineral deposits inside the drum and agitator.
- Set the machine to the largest load setting and hottest water temperature
- Add 4 cups of white vinegar and start the cycle, let it agitate for 2 minutes, then pause and let it soak for 1 hour
- Add 1 cup of baking soda, resume and complete the cycle
- Wipe inside the drum, lid, and control surfaces with a cloth
How Often
- Cleaning cycle: monthly
- Gasket wipe: after every load
