How to Clean Your Washing Machine

Washing machines clean your clothes but rarely get cleaned themselves — and they need it. Mould, detergent buildup, and fabric softener residue accumulate inside and cause musty smells that transfer to your laundry.

Front-Load Washers: The Mould Problem

Front-load washing machines are significantly more prone to mould than top-loaders. The rubber door gasket (the seal around the door) traps moisture and creates ideal mould conditions. If your clothes come out smelling musty, this is almost certainly the cause.

Cleaning the door gasket:

  1. Open the door and pull back the rubber gasket to expose the folds
  2. Wipe thoroughly with a cloth soaked in a bleach and water solution (1:10)
  3. Get into all the folds — this is where mould hides
  4. Wipe dry completely

After cleaning: Leave the door open between washes to allow the gasket to dry. This is the single most effective prevention measure for front-loader mould.

Cleaning the Drum (All Washer Types)

Bleach method: Add 1 cup of bleach to the detergent dispenser. Run the longest, hottest cycle available (usually "clean washer" or "sanitize" cycle). Wipe the drum with a cloth after.

Vinegar + baking soda method (gentler alternative):

  1. Add 2 cups white vinegar to the detergent dispenser
  2. Run a hot cycle
  3. Add ½ cup baking soda directly to the drum
  4. Run another hot cycle

Cleaning the Detergent Dispenser

Remove the detergent drawer (most pull straight out) and soak in warm soapy water. Scrub with a brush to remove caked-on detergent. Rinse and replace.

How Often

Monthly for front-loaders. Every 2–3 months for top-loaders. Leave the door open between uses (both types) to prevent moisture buildup.
