The temperature at which you should wash white clothes depends on several factors, including the material they are made of, the level and type of stain they have, and the presence of patterns or stripes. Here are some general guidelines:
-
Cold water: Cold water cycles (between 60 and 80ºF (15 and 30ºF)) cause the least amount of damage to fabrics, so it’s a good idea to wash garments (white or not) you’re unsure about in cooler temperatures to avoid disappointment when you pull your clothes out of the drum. Cold water is also recommended for dark or bright colors that bleed or delicate fabrics.
-
Lukewarm water: White linens should be washed in lukewarm water, which generally falls between 90 to 110 degrees Fahrenheit.
-
Hot water: White clothes should generally be washed using hot or warm water (130°F or above) to effectively remove stains and bacteria. However, some fibers will shrink and become weaker in hot water, so its best to use lukewarm water, ranging between 90 to 110 degrees Fahrenheit, for delicate whites.
Its important to read the care label on your clothes to determine the appropriate water temperature for washing. Additionally, washing white clothes separately can help retain their whiteness and prevent color transfer.
