Washing at lower temperatures to save the world

November 24, 2014 by Ville Raivio

Most shirts have a washing tag with a recommendation of a 40°C washing temperature, but some of us adamantly wash at 60°C for thoroughness and OCD-friendly tendencies. K. Laitala and H. Mollan Jensen from Norway have kindly researched if washing laundry at lower degrees, to save water heating expenses and energy, will clean as well as doing so at higher temperatures. Their concrete abstract affirmingly states: “…this confirms that modern detergents are suitable for wash at 30°C, and the soil removal will in most cases be satisfactory for household use instead of the more common wash at 40°C.”

Kindly wash at 40°C or less to save the world.

    I can attest to the fact that shirts washed at 30 Celsius come out perfectly clean. They also last longer and experience less shrinkage than shirts washed at higher temperatures. I would also suggest never drying them in a tumble dryer.
