Small Trick, Big Change: How to Clean Your Washing Machine Without Harsh Chemicals

If you’ve ever opened your washing machine and noticed an unpleasant smell, you’re not alone. A smelly washing machine is a common problem that can ruin the freshness of clean laundry. In this article, we explain what causes the issue, how to clean your washing machine effectively, and how to keep it fresh using eco-friendly solutions. We’ll also show you how laundry sheets and laundry perfumes can improve your washing experience – all while protecting the planet.

What causes washing machine odour?

Bad smells in washing machines can come from several sources. Here are the most common causes:

1. Detergent and softener build-up: Using too much detergent, especially liquid types, can leave sticky residues in the drum, door seals, or detergent drawer. Over time, these residues grow mould and create unpleasant odours.
2. Moisture and mould: Washing machines are often damp environments – perfect for mould and bacteria. Leaving the door closed or wet laundry inside after a cycle encourages microbial growth that causes smells.
3. Hard water and mineral deposits: In areas with hard water, calcium and other minerals build up inside the machine, trapping dirt and worsening odours. Studies show up to 60% of households experience hard water issues.
4. Clogged filters and hoses: Uncleaned filters and drain hoses can hold dirt, lint, and fabric fibres that start to smell over time.

How to clean and deodorise your washing machine

Fortunately, there are easy, eco-friendly ways to clean your washing machine and get rid of smells:

1. Regular cleaning with vinegar and baking soda:
   • How to: Pour 200 ml of white vinegar into the drum and add 2 tablespoons of baking soda. Run an empty cycle at the hottest temperature (ideally 60–90 °C / 140–195 °F). Vinegar dissolves limescale and mould, while baking soda neutralises odours.
   • Tip: Repeat every 1–2 months to prevent smells from returning.
   • Eco benefit: White vinegar and baking soda are natural, biodegradable, and affordable alternatives to chemical cleaners.
2. Cleaning the seals and detergent drawer:
   • Door seals are breeding grounds for mould. Wipe them with a cloth soaked in a 1:1 mix of vinegar and water. Remove the detergent drawer and scrub it with an old toothbrush to get rid of residue.
   • Tip: After every wash, leave the door and drawer open to air dry.
3. Checking the filter and drain hose:
   • Check the filter (usually at the bottom of the machine) and remove any debris, hair, or fabric fibres. Flush the drain hose with hot water if possible to eliminate build-up.
   • Eco benefit: Regular maintenance extends the life of your washing machine, saving resources and waste.
4. Use eco-friendly detergents:
   • Switch to laundry sheets – a great alternative to liquid or powder detergents. These thin, dissolvable sheets are chemical-free, fully biodegradable, and leave no residue. Their concentrated formula cleans effectively and prevents odour-causing build-up. The compact, plastic-free packaging also reduces environmental impact.
   • Tip: One sheet is enough for a regular load – simple and waste-free!
5. Add freshness with laundry perfumes:
   • To keep your laundry (and washing machine) smelling fresh, use laundry perfumes. Add a few drops to the softener compartment – they give clothes a long-lasting, pleasant scent.
   • Eco benefit: Choose perfumes made with natural ingredients and recyclable packaging to minimise environmental impact. We currently offer four scents – find your favourite in our online shop.

How to prevent smells and protect the planet

• Don’t overload the washing machine: Too many clothes prevent proper rinsing, leading to residues and odours.
• Wash at lower temperatures: For everyday laundry, 30–40 °C (86–104 °F) is enough to save energy. Run one hot cycle per month with vinegar to disinfect.
• Use less detergent: Too much detergent increases build-up and environmental strain. Laundry sheets are perfectly dosed and residue-free.
• Use natural alternatives: Replace fabric softeners with 50 ml of vinegar or a drop of essential oil – for soft, fresh laundry without harsh chemicals.
• Invest in a water softener: If you have hard water, a softener reduces mineral deposits and prevents odours. Magnetic softeners are eco-friendly and maintenance-free.

Benefits of a clean washing machine

• Fresh laundry: A clean machine means fresh, pleasant-smelling clothes.
• Longer lifespan: Proper care extends your machine’s life and saves repair costs.
• Eco benefits: Using natural cleaners and laundry sheets reduces plastic and chemical consumption.
• Healthier home: Less mould and bacteria – ideal for families with children or allergies.
