Most washers feature temperature settings separate from other settings, so users can choose the "cold" setting to wash their clothes in cold water. Washer options such as "hand wash" and "delicates" typically use cold water for washing and rinsing.
Instead of temperature settings, some washing machines use only descriptive settings such as "quick wash," "permanent press" and "heavy duty"; typically these options wash in hot water. Cold-temperature settings are best used with loads that are likely to bleed dye in warm or hot water, such as loads with mixed colors. Additionally, cold water is better for washing out difficult stains, such as blood, which may set into the fabric with heat and become more difficult to remove.
