For most everyday laundry, cold water is a sensible default if the care label allows it. Choose warm or hot only when the garment’s label and your washer’s instructions permit it. The words on a washer’s temperature dial are not universal temperature measurements: the water that reaches a load can depend on the model and the incoming supply.
Start with the garment care label
Use the care label as the limit for the garment, then choose a compatible washer setting. In the United States, the Federal Trade Commission’s care-label glossary defines hot as an initial water temperature of 112–145°F (45–63°C), warm as 87–111°F (31–44°C), and cold as up to 86°F (30°C). These definitions describe care-label terminology; they do not promise that a washer setting with the same name will deliver that temperature. See the FTC care-label rule and glossary.
If the label limits the temperature, do not exceed that limit just because a washer offers a hotter cycle. When the label and washer instructions do not make a choice clear, check the garment or appliance manufacturer’s guidance.
Which temperature should you choose?
| Laundry situation | Practical choice | What to check |
|---|---|---|
| Ordinary everyday clothes | Cold is a reasonable default. | Confirm the care labels permit cold washing. |
| Oily stains or a reason to wash warmer | Consider warm or hot only if appropriate. | Check the garment label and the washer manual. There is no single temperature chart that applies to every stain and fabric. |
| Delicates, dark colors or shrink-prone garments | Follow the garment’s stated temperature limit. | Do not assume a fabric category has one safe temperature for every item. |
| A setting seems cooler than expected | Consult the manual for the exact washer model. | Incoming water conditions and machine design can affect the water temperature. |
Why cold is a useful default
ENERGY STAR says cold water generally cleans well except when dealing with oily stains, and recommends cold washing as a best practice. It also reports that water heating consumes about 90% of the energy it takes to operate a clothes washer. Switching from hot to warm can cut energy use in half, according to ENERGY STAR; its cited page does not state a publication year for these figures.

If you wash cold often, cold-water laundry detergent is an optional category to consider. It is not required by the guidance above, and no particular detergent brand is established as superior here.
What cold, warm and hot mean on a washer
Washer dial labels should not be treated as cross-brand standards or as a built-in thermometer. For example, Whirlpool lists approximate temperatures for some settings: Hot 101–115°F, Warm 80–85°F, Cool 65–75°F, Cold 55–65°F, and Tap Cold at tap temperature. Those are Whirlpool examples, not universal definitions; Whirlpool also notes that settings vary by model. Its temperature-setting information and consumer guide to washer settings should not be used to infer another brand’s exact temperatures.

LG explains that warm water mixes hot and cold water, so pipe temperatures and the distance from the water heater can affect the result. GE Appliances likewise notes that inlet temperature matters and directs users to the manual for the specific washer. If you need to know how a particular selection behaves, consult that model’s manual rather than relying on another washer’s figures.

- Read the care labels. Identify each item’s temperature limit before selecting a wash temperature.
- Consider the load’s soil. Cold is suitable for many ordinary loads; for oily soil or another reason to use warmer water, first confirm that the garments can tolerate it.
- Check the washer manual. Use the instructions for your exact model to understand its cycles and temperature options.
- Account for incoming water. If the result seems unexpectedly cool, supply temperature and machine design may be factors; a setting name alone does not establish the measured temperature.
The FTC definitions apply to US care-label terminology, while the Whirlpool figures are examples for that manufacturer’s context. Neither should be substituted for the exact care label and washer manual when choosing a setting.
