Why Clean Your Washing Machine with Vinegar?
Over time, washing machines accumulate detergent residue, hard water mineral deposits, mould, and mildew — especially in the drum, door seal, and detergent drawer. This causes musty smells and can even transfer to your clothes. White vinegar (acetic acid) is one of the most effective, affordable, and safe ways to break down this buildup without harsh chemicals.
What You Need
- 2–4 cups of white distilled vinegar (5% acidity)
- 1/2 cup baking soda (optional, for extra deodorising)
- An old toothbrush or small brush
- A clean cloth or sponge
Important: Use plain white distilled vinegar — not apple cider vinegar or flavoured vinegar. Do not mix vinegar and bleach — this creates toxic chlorine gas.
How to Clean a Front-Load Washing Machine with Vinegar
- Clean the door seal (gasket): Mix equal parts vinegar and water in a spray bottle. Spray inside the rubber door seal, paying attention to the folds where mould hides. Scrub with the toothbrush, then wipe clean with a cloth.
- Clean the detergent drawer: Remove the detergent drawer completely. Soak it in warm vinegar solution for 15 minutes, scrub, rinse, and replace.
- Run the vinegar cycle: Pour 2 cups of white vinegar directly into the drum (not the detergent drawer). Set the machine to the hottest and longest wash cycle available. Run the cycle completely.
- Run a baking soda cycle (optional): Add 1/2 cup of baking soda directly to the drum and run another hot cycle. This neutralises any remaining vinegar smell and brightens the drum.
- Wipe down: After cycles complete, wipe the drum, door glass, and door seal with a clean dry cloth.
- Leave the door open: After every wash (not just cleaning cycles), leave the machine door slightly open to prevent moisture and mould buildup.
How to Clean a Top-Load Washing Machine with Vinegar
- Start the hot cycle: Set the machine to the hottest, largest capacity cycle. Start the machine and let the drum fill completely with water.
- Add vinegar: Pour 4 cups of white vinegar into the water. Close the lid and let it agitate for 1–2 minutes to mix the vinegar thoroughly.
- Pause and soak: Pause or stop the machine and let the vinegar water soak for 30–60 minutes. This dissolves mineral deposits and detergent residue.
- Clean the rim and agitator: While soaking, dip a cloth in the vinegar water and wipe the inside rim, the top of the agitator, and the lid.
- Complete the cycle: Resume the wash cycle and let it complete fully.
- Add baking soda (optional): Start a second hot cycle, add 1 cup of baking soda, and run to completion for extra freshness.
How Often Should You Clean Your Washing Machine?
| Usage Level | Recommended Cleaning Frequency |
|---|---|
| Light (1–2 loads/week) | Every 3 months |
| Moderate (3–5 loads/week) | Every month |
| Heavy (daily washing) | Every 2–3 weeks |
Tips to Keep Your Washing Machine Clean Between Vinegar Washes
- Use the correct amount of detergent — too much creates soap scum and mould. HE (High Efficiency) detergent produces less foam.
- Leave the machine door slightly ajar after every wash to let moisture escape.
- Remove laundry promptly after the cycle ends — clothes sitting in a closed, damp drum encourages mould.
- Wipe the door seal dry after each wash (especially front-loaders).
- Run a hot wash cycle (60°C+) once a week to kill bacteria and bacteria.
Frequently Asked Questions
Can vinegar damage the washing machine?
White vinegar is safe for washing machines when used correctly. However, very frequent use of large amounts of vinegar (every week) can gradually degrade rubber seals and hoses over time. Using vinegar monthly as a cleaning agent is safe for most machines. Check your machine manufacturer’s manual — a few brands (notably some Miele models) advise against vinegar in their machines.
How much vinegar should I use to clean a washing machine?
For front-loaders: 2 cups poured directly into the drum. For top-loaders: 4 cups added after the drum fills with water.
Should I use vinegar in the detergent drawer or the drum?
Pour vinegar directly into the drum, not the detergent drawer. In the drawer, vinegar may not reach the drum in adequate quantity to be effective. The drum is the target.
Can I mix vinegar and baking soda in the washing machine at the same time?
You can use them, but not simultaneously in the same cycle — they neutralise each other and lose their cleaning effectiveness. Use vinegar in the first cycle, then baking soda in a second cycle.
