There are habits that pass from generation to generation without questioning their true importance. One of them is the way we wash clothes, especially the “old rule” of not mixing colors in the machine. For years, this idea was seen as domestic law, but modern detergents and machines today raise the question: is it really a mistake to mix clothes of different colors?
Mixing colors continues to be a risky practice, especially when it comes to new pieces or those in dark and intense tones, according to the organization recognized as an international scientific reference in good practices for washing and preserving textiles, American Cleaning Institute (ACI).
Pigment transfer is a common phenomenon: when a fabric releases dye, that color can be absorbed by other lighter fabrics, leaving stains or gray tones. Therefore, these reference entities in home care still recommend separating items by color groups (white, light and dark) to preserve the original tone and shine of the clothes.
When can you mix?
Despite precautions, technological developments have changed the outlook, says the same source. Today’s washing machines use shorter cycles and lower temperatures, reducing the release of pigments.
Modern liquid detergents also have agents that stabilize the color and prevent paints from mixing. Therefore, it is generally safe to wash items with similar tones together, such as blues and grays or beiges and creams, as long as they have been washed several times and do not release color. Even so, contact between whites and dark colors should always be avoided.
Role of tissue and temperature
Not all materials react the same way. Delicate fabrics tend to absorb pigments more easily, while washing at high temperatures increases the risk of discoloration. According to the same source, it is best to choose cold water and detergent programs suited to the type of fabric, ensuring effective cleaning without compromising the colors.
Washing inside out and not overloading the machine are simple gestures that can also make a difference.
Little tricks that help
Before mixing clothes, it’s worth doing a quick color fastness test: moisten a discreet area of the item and wipe it with a white cloth; if it gets dyed, wash separately.
Drying clothes in the shade and avoiding direct heat also helps to preserve their original appearance. These are details that extend the useful life of the pieces and keep your wardrobe looking new.
How does it work in practice?
Mixing colors in the washing machine is possible, but must be done with care. Grouping similar tones, preferring cold washes and not combining whites with darks remains the golden rule, according to .
Classic separation is still the safest method for those who want to avoid surprises and keep their clothes in good condition. A few minutes of attention before washing make all the difference in the results.
