Do you wash clothes without detergents? I've been doing so for nearly a month since summer officially began in early May. In the summer, most of my shirts, both long- and short-sleeved, are "stained" with perspiration, so a fast wash with pure water is all that is required. It's not about costs; detergents are not particularly pricey. It's all about reducing plastic pollution. Many detergents are known to contain microplastics, which are eventually washed into the sea and endanger marine life. In 2019, a group of Columbia University researchers demonstrated the dangers of detergents for environmental health in a well-recognized experiment.
