However, it can also cause some fabrics to shrinkor fade.
As temperature increases, thermal energy increases, contributing to improved cleaning, Gagliardi says.
So, utilize cold cycles for more delicate items, like lingerie or wool fabrics.
(Gagliardi notes that wool clothes can permanently shrink if washed in warm or hot water.)
Cold water is also the best choice for bright or dark-colored items, to prevent fading.
However, there is a disadvantage to washing clothes in colder water.
Its that [clothes] dont get very clean,” Gagliardi says.
Cold water also varies seasonally and regionally.
Cold tap water in some parts of the country will be too cold for adequate cleaning, Gagliardi adds.
Some washers have specific controls for the rinse cycle, which you’re free to set to cold.
Using a cold-water rinse will reduce your energy usage slightly, as well.
Water below 60 degrees Fahrenheit is too cold for most detergents and won’t clean your clothing well enough.
A kitchen thermometer is your best bet for testing the temperature of your wash water.
Grab a meat or candy thermometer and a cup, and head to your washer.
you might also just stick the thermometer straight into the wash water.
Either way, you’ll get an accurate read and can adjust from there if necessary.
