What temperature you should wash clothes at depends on the type of fabric and the degree of dirt. Here's a general guide for wash temperatures:
1. 30°C - Cold water
-
Good for: Delicate fabrics such as silk, wool, and fragile synthetic fibers. Cold water is also good for preserving colors and washing clothes that aren't heavily soiled.
-
Advantages: Saves energy, reduces the risk of clothes shrinking or colors bleeding.
-
Disadvantages: There is a risk that the clothes won't be completely clean, and it's easy to overdose on detergent to compensate for the low temperature.
2. 40°C - Lukewarm water
-
Good for: Most clothes, including cotton, synthetic fabrics, and blends. This temperature is also suitable for underwear, lightly soiled clothes, and dark colors.
-
Advantages: Warm enough to remove light dirt and sweat but gentle enough for most fabrics.
3. 60°C - Warm water
-
Good for: White cotton clothes, bed linens, towels, and heavily soiled items. This temperature is also effective for killing bacteria and dust mites.
-
Advantages: Removes tougher stains and partially disinfects the laundry. The detergent works at full efficiency.
4. 90°C - Very hot water
-
Good for: Extremely dirty clothes and items that need disinfection, such as hospital clothing or certain types of kitchen towels.
-
Advantages: Maximum cleaning power and disinfection.
Tips for washing temperatures:
-
Check the care label: Always follow the instructions on the garment's care label. It will indicate the maximum temperature the item can tolerate.
-
Don’t buy clothes that can’t be washed: Read the care label in-store and avoid buying garments that are so delicate they can’t handle normal washing. Such items will become unhygienic and not last long, making them a poor choice for the environment and climate. The best for the environment is always to use things for a long time.
-
Reduce energy consumption: Wash at lower temperatures when possible. Modern detergents are often effective at lower temperatures, so you can save energy while still getting clean clothes. However, don’t overdo it, as producing stronger detergents also uses energy. Additionally, consider the environmental impact of where the wash water ends up. Remember that energy-saving calculations are entirely dependent on the type of energy being used.
-
Prevent shrinkage and color fading: For delicate clothes and colored items that are prone to fading, lower temperatures are best.
-
Pre-treatment: Stains can be pre-treated before washing to ensure they come out even at lower temperatures.
In summary, choose wash temperature based on the fabric type and level of dirt, and always follow the manufacturer's instructions to protect your clothes.
