Cool cleaning

Wash your clothes at 30°C

Wash your clothes at a cool and efficient 30°C and all that will shrink is your carbon footprint (oh, and your energy bills). Most modern detergents are designed to work perfectly at cooler temperatures, so you'll still get your whites sparkling.


Here are a few reasons to take action.

Long lasting clothes

There's nothing more frustrating than ruining your warmest woollies, shrinking your favourite skirt, or running the dyes of your smartest top because of washing them too hot. Avoid the risk: wash on cool.

Climate change

We've all become so accustomed to having piping hot water at the twist of a tap that it's easy to forget what an energy-intensive luxury it is.


CO2 per year saved by washing your clothes at 30°C


Energy costs money. By washing at 30°C instead of 40°C, you could cut the cost of each cycle by a third. Ok, so it's not quite like winning the jackpot, but it's enough to treat yourself to that slightly pricier jumper next time you're out shopping.

Global Goals

In September 2017, an historic agreement was signed by UN member nations agreeing to work towards 17 Global Goals for Sustainable Development by 2030, otherwise known as the SDGs.

Achieving these ambitious goals will require action from governments, businesses, NGOs, and individuals alike. We can - and must - all play our part.

By making the 'Cool cleaning' pledge, you are contributing to the following SDG targets:

12.8: By 2030, ensure that people everywhere have the relevant information and awareness for sustainable development and lifestyles in harmony with nature

13.3: Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning


Well, this one is pretty self-explanatory. Turn the dial down to 30°C.

The washing powder

Modern detergents are designed to work perfectly at 30°C, so unless you've been rolling around in the mud or have been eating like a complete mucky-pup, then your clothes should emerge as fresh and clean as ever.

The Ethical Superstore are a pretty friendly bunch who have some great offers on all sorts of household goods - including some nice eco friendly washing powder and free fabric conditioner, helping to keep clothes cleaner at a lower temperature.

The washing machine

Perhaps you have a pretty old washing machine that doesn't have a 30°C setting? If that's the case then it's probably time to upgrade to an AAA rated machine.

Otherwise, it's pretty simple: set the temperature to 30°C, and off you go.

There are a few other laundry-related good deeds you can do while you're at it:

  • Always wait until you have a full load
  • Use the Eco settings wherever possible, they use less water
  • Use eco-friendly detergent (think of the fishies!)
  • Hang your laundry to dry naturally

Success Stories


in total



I was pleasantly surprised how little difference there seemed to be in the wash between low temperature and a normal 40 degree wash.

Made no negative impact on my washing for a good cause :)

I try to make my washes as infrequent as possible, but when I do put a wash on I now make sure that it's on 30 every time!

Washing at 30 made no difference to the washing so I will continue to do so.
