10 Tips to wash less & better

At La Sirène, we believe in looking after both your clothes and the planet. Here are 10 simple steps to protect your wardrobe while being kinder to the environment.

1. Wash at 30°C or lower

Heating water is one of the biggest factors in laundry’s environmental impact. It takes three times more energy to heat water to 90°C than to 30°C. High temperatures also weaken fabrics.

2. Choose shorter cycles

Quick washes save energy and water, while being gentler on fibres. They also help your washing machine last longer.

3. Use eco-friendly detergents

Opt for biodegradable, gentle detergents. Favourites include Marseille soap–based formulas and green-certified brands. They’re softer on fabrics and better for nature.

4. Stick to the right dosage

Using more detergent doesn’t mean cleaner clothes. In fact, overdosing often reduces efficiency especially with eco-friendly products. Always follow the recommended amounts, or even less when possible.

5. Turn clothes inside out

Especially jeans, trousers, shirts, and tees. This reduces friction and fading. For delicates and lingerie, use a washing bag to protect fabrics from zips, Velcro, and hooks.

6. Use a laundry bag

Essential for synthetic fibres like polyester or nylon. These bags trap microplastics that would otherwise flow out with wastewater and end up polluting the oceans.

7. Let clothes air-dry

Tumble dryers may be quick, but they crease fabrics, weaken fibres, and consume huge amounts of energy. Whenever possible, air-drying is best.

8. Skip the ironing when you can

Not every garment needs ironing. Many fabrics don’t crease, and others will smooth out if hung straight after washing. Less ironing means less water and energy wasted.

9. Store clothes properly

Fine fabrics and easily creased garments (like dresses and shirts) should be hung on hangers. Knits and stretch fabrics, however, are best folded to preserve their shape.

10. Care for your wardrobe

Air your wardrobe regularly to prevent mould, mites, and musty smells. Use lavender sachets or scented wax tablets for freshness. To protect against moths, cedarwood blocks are a natural and effective option.
