Is it better to wash at 40 or 60 degrees?

Should You Wash at 40 or 60 Degrees?

When it comes to washing clothes, temperature matters—but not always in the way you might think. Most everyday laundry doesn’t need a 60-degree cycle. In fact, a 40-degree wash is usually more than enough for lightly soiled clothes. Modern eco-friendly detergents are specially formulated to perform well even at lower temperatures, meaning you can tackle common stains effectively without turning up the heat.

Washing at 40 degrees strikes a balance between cleanliness and care. It’s gentle on fabrics, helps preserve colours, and uses significantly less energy than higher-temperature cycles. Many people are surprised to learn that even a 30-degree wash can handle routine laundry when paired with a good-quality detergent.

So when should you go for 60 degrees? Reserve that higher temperature for specific situations—like heavily soiled workwear, cloth nappies, or bedding after an illness. At 60°C, you get a more thorough sanitisation, which helps eliminate bacteria and stubborn residues that lower temperatures might miss.

Still, cranking up the heat every time isn’t just unnecessary—it’s hard on your clothes and the planet. Higher temperatures can cause fibres to break down faster, leading to shorter garment lifespans. Plus, the energy use adds up over time, both on your bills and your carbon footprint.

The bottom line? Stick to 30 or 40 degrees for most of your laundry. Save the 60-degree cycle for when it’s truly needed. Not only will you keep your clothes cleaner, but you’ll also extend their life—and do your part for a more sustainable routine.
