Many modern detergents are formulated to work just as well in cooler water, so unless your clothes are heavily soiled, 30°C is often enough.


🧺 4. Modern Detergents + Cooler Water = A Better Combo

Thanks to advances in laundry detergent technology, most mainstream products now clean efficiently at lower temperatures. Cold wash detergents are specially designed to dissolve and lift dirt even at 20°C–30°C.

So, unless you’re dealing with greasy, stained workwear or infectious laundry, you really don’t need 40°C.


🧊 When to Choose 30°C, 40°C, or 60°C?

Here’s a quick cheat sheet:

Temperature Best For Caution
30°C Everyday clothes, delicates, synthetics Saves energy, gentler on clothes
40°C Lightly soiled items, colorfast cotton Not hot enough to disinfect
60°C Towels, bedding, underwear, heavily soiled items More energy use, some fabrics may shrink

📌 Final Thoughts: It’s Not Just About the Number

While 40°C may seem like a balanced choice, it actually falls into a grey zone—not hot enough to sanitize, not cool enough to protect delicate fabrics. That’s why many laundromats and laundry professionals recommend either dropping down to 30°C for regular loads or going up to 60°C when hygiene is a concern.

So next time you do laundry, give that temperature dial a second look—your clothes, energy bill, and skin might thank you!
