How modern detergents changed the temperature rules
Some laundry detergents are formulated for cold water. Check the actual product for its permitted temperature, dose and compatible machines instead of assuming every liquid, powder or packet has the same directions.
A colder setting can reduce the need to heat water, but it does not promise the same result for every textile or stain. Dose, cycle, loading, rinsing and drying also affect the outcome.
- Check whether the actual detergent is suitable for the permitted temperature.
- Separate items by care needs and colorfastness; cold water is not a guarantee against dye transfer.
- Follow washing and drying limits; cold water does not rule out shrinkage or loss of shape.
