flag A study finds cold, short washes reduce fabric damage and microfiber pollution better than hot, long cycles.

flag A University of Leeds study, supported by Procter & Gamble and published in Dyes and Pigments, found that a 30-minute cold wash at 30°C significantly reduces fabric damage, color fading, dye transfer, and microfiber shedding compared to standard 40°C, 85-minute cycles. flag Researchers tested various t-shirts using white "receiver" fabrics and collected wash water to measure microfibers, finding that shorter, cooler cycles better preserved clothing and reduced environmental impact, even after multiple washes. flag The findings were independently reviewed despite industry funding.
