Colder temperatures are gentler on textiles, so even if your favourite shirt can be washed on a hot wash, you might want to consider washing it at 30 degrees, a cold wash. It minimises the risk of shrinkage and colour bleeding, too.
A setting of 30°C is usually recommended for washing delicate clothes when combined with a delicate cycle, and not on quick wash. This means low temperatures can be used with items like wool and silk when set to a delicate or hand wash cycle.
Observe the care label
Both washing temperatures that are too high and drying that is too hot will cause your clothes to shrink. It is therefore advisable to wash at low temperatures. Many items of clothing can only be machine washed at 30 degrees Celsius, while delicate fabrics such as silk can only be washed by hand.
This is great for the environment as it saves on power and energy needed to heat the water; this will also save you money too. However, we still advise that you do a 'maintenance wash' every so often to clean away any grease, mould and bacteria that has not been killed off by washing at 30° or 40°.
Nope. 30 degrees doesn't kill bacteria and that bacteria is transferred to all/other items in that wash.
Does A 30-Minute Quick Wash Clean Clothes? Absolutely. Many washing machines allow you to perform a quick wash that actually takes 30 minutes, rather than the usual 15 minutes. This means that it is better equipped for fully refreshing your clothes.
Some people advise 30˚C, saying anything hotter will make towels stiff and scratchy or fade their colour. Others believe hotter temperatures between 40˚C and 75˚C are the only way to kill bacteria. We recommend washing coloured towels at 40˚C and white towels between 60˚C and 75˚C.
Helping your clothes stay vibrant and last longer - Washing with a warm water temperature − on cycles at 40°C or higher – is more suitable for heavy soiling, but can come with a few downsides such as colours fading and shrinking fabrics.

While 30°C is generally considered a “cold” wash, some organisations, such as the EU's Ecodesign Initiative, believe that 25°C or even 20°C is the perfect temperature for a cold cycle. The colder you go, the more energy you'll save and the less harmful synthetic microfibers you'll shed.
Is 30 degrees a cold wash? No, a 30ºC wash is generally considered a warm wash. A cold wash is below 20°C and is usually reserved for clothes that are very delicate. Washing at 40ºC is also considered a warm wash, while 60ºC is a hot wash and 90ºC is a very hot wash.
The washing temperature should not be more than 30 degrees and the wash cycle should be over as quickly as possible. You should specifically tackle strong stains before washing.
When to Use Warm Water – For man-made fibers, knits and jeans, use warm water (90°F). Most of your clothes can be washed in warm water. It offers good cleaning without significant fading or shrinking. When to Use Cold Water – For dark or bright colors that bleed or delicate fabrics, use cold water (80°F).

If you're particularly worried about some garments, you can always wash and dry them on a lower heat, say 30 °C. While lower temperatures won't prevent all shrinkage, it will significantly reduce it. One other thing you might see on a garment label is the phrase “preshrunk”.
What does 30, 40, 50 and 60 mean in laundry symbols? The numbers 30, 40, 50 and 60 reference water temperature in degrees Celsius. A cold wash is around 30°C (85°F), warm is 40°C (105°F), warm/hot is 50°C (120°F) and hot is 60°C (140°F).

In general, when the wind chill is 32° and above, it's safe to be outside. In temperatures 13° to 31°, you should take indoor breaks every 20-30 minutes. For wind chills of 13° and below, move activities indoors as frostbite can quickly set in. How Cold Is Too Cold to Go Outside?

Avoid hot water – high temperatures will cause cotton to shrink, so opt for a delicate cycle or a cold wash to avoid your favorite cotton items from shrinking. Flip them inside out – to protect the outside of the garment from the abrasive agitation of the washing process, turn them inside out.
Most washing machines have a cold wash setting, meaning, the water isn't heated at all, but a temperature up to 30°C is still considered a cold wash. It's a high enough temperature for delicate fabrics, bright colours that could run or fade and lightly soiled clothes.
Bacteria stops growing at 8°c and below, and at 63°C or above. You should store food at these temperatures. Bacteria is killed at 100°C and above (boiling point). Bacteria definately won't grow at -18°C (freezer temperature), but might still stay live.
Incorporating natural additives such as vinegar or baking soda during the wash cycle can further enhance softness. Advanced drying methods, utilizing commercial-grade dryers with precise drying cycles, play a crucial role in preserving the towels' plush texture.
Proctor & Gamble tested its Ariel Gel for effectiveness and stain removal at 20C, while Which? magazine found in a test that an olive oil stain was the only one a 20C wash couldn't shift compared with a 40C wash. It's got to be worth a try.
