Real benefits of washing using cold water

Changing your laundry habits from using hot/warm water, to using cold water can significantly reduce your utility bill, reduce your energy consumption for laundry, and reduce your impact on the environment.

And your sheets will still be free of blemishes, bacteria, and feeling soft as ever!

Cold water detergents exist, and actually work

There are 3 factors that come into play for clean sheets: thermal energy, mechanical energy, and chemicals. When one factor was reduced in power, the other two had to work overtime. So to reduce energy consumption of washing machines, companies created cold water activated detergent that let’s you forget mum’s advice that your sheets need hot water to be rid of all that nasty residue!

Companies have been making cold water activated detergent for many years which do equally, if not better at cleaning your fabrics, and cost around the same amount to make. It has been reported that “some even contain chemicals that coat fabric fibers so that they are less likely to absorb dirt in the interval before the next washing”.

Despite the vast availability of  cold water activated detergent, most of the world has still not made the switch from warm/hot to cold water washing. Procter & Gamble estimate that 38% of laundry loads globally are done using cold water.

Reduce the damage to your sheets

Your sheets go through a normal wear, and tear which is expected. You sleep 6-9 hours a night, shedding skin, losing bodily fluids, and if you’re lucky, there’s some fun with someone else. Aside from this nightly rumble, every week you wash your sheets, and either use a dryer or air dry it, then iron it.

So why wouldn’t you wash your sheets in a way that preserves the quality of them? Koala’s All Season Sheets have been lab tested for colour fastness, light, and durability so they’re designed to last a long time, and maintain their softness…but you still need to follow our care instructions which have been proven to preserve colour, avoid shrinkage, and reduce the natural wearing down of the fibre.

Using hot water speeds up the process of the fibres breaking down by fading the colour, promoting shrinkage, and actually promotes wrinkles which means extra time doing the ironing.

Reduce your utility bill

Washing your clothes, and sheets at the lowest possible temperate will do wonders for your utility bill. According to the US Environmental Protection Agency, “hot water heating accounts for about 90 percent of the energy your machine uses to wash clothes — only 10 percent goes to electricity used by the washer motor”.

Imagine how amazing it will be when you look at your water bill to see it slashed that significantly by doing something so simple as setting the washer temperature a bit colder, and switching detergent?

According to Canstar Blue, shifting from a hot or warm washer to a cold wash can reduce your annual water bill by $60 if you do 3 loads per week.

Reduce your environmental impact

As stated earlier, switching to washing with cold water means slashing up to 90% of your washing machine energy usage which results in a reduction in your carbon footprint.

It’s important that we look at our actions, and how it affects the environment. Something as trivial to us like washing our clothes has been detrimental to the environment. For better understanding, your load of washing, with variations of drying produces this amount of CO2e to the environment:

0.6 kg CO2e washed at 30°C, dried on the line
0.7 kg CO2e washed at 40°C, dried on the line
2.4 kg CO2e washed at 40°C, tumble-dried in a vented dryer
3.3 kg CO2e washed at 60°C, dried in a combined washer-dryer

So why stop at just your washing machine? Using your dryer every two days is the equivalent of “flying from London to Glasgow and back with 15-mile taxi rides to and from the airports”, or 440kg of carbon dioxide.

Do your part, and swap to cold water when you wash, and air dry when possible!
