Introduction:
When it comes to doing laundry, many of us follow the simple rule of washing clothes at 40°C (104°F) as a standard setting. It’s considered a safe, middle ground temperature to keep your clothes clean while protecting their fabric. However, recent findings reveal that washing your laundry at 40°C may not be the best option. In fact, it could be doing more harm than good, both for your clothes and your washing machine.
In this article, we’ll explore why you should reconsider washing your laundry at 40°C and the surprising reasons behind this advice. We’ll also provide some expert tips on how to optimize your laundry routine, save energy, and extend the life of your clothes and washing machine.
Ingredients:
Laundry detergent (preferably eco-friendly, if possible)
Clothes (dirty) – Always check fabric care labels to choose the best washing settings
Water (Hot or Cold, depending on the temperature preference)
Optional: Fabric softener (for added softness)
Optional: White vinegar (for cleaning and odor removal)
Instructions:
Understanding Temperature Settings: The first step is understanding the effect different temperatures have on laundry. Washing at 40°C seems like a safe bet, but the truth is that many types of bacteria, germs, and allergens do not get properly eliminated at this temperature. Even though it’s generally seen as a gentle wash, 40°C water may not be hot enough to kill certain pathogens or remove stubborn stains.
Why 40°C May Not Be Effective: At 40°C, some detergent ingredients don’t dissolve or activate fully, which means that they may not be as effective at removing dirt or grime. For certain heavy-duty loads (like towels, bedding, or workout clothes), hotter water—around 60°C (140°F)—is often needed to ensure a deeper clean and to properly sanitize your fabrics.
