The most sustainable way to do laundry is to wash less often, wash in cold water, use the smallest effective amount of a low-impact detergent, and dry clothes without heat whenever possible. Combining these habits cuts energy use, reduces microfiber pollution, and helps clothing last longer—often the biggest hidden waste in a laundry routine.
Not every item needs a full wash after one wear. Airing out lightly worn clothes, spot-cleaning small marks, and rotating garments can reduce the number of loads you run each week. Fewer loads means less water, less detergent, and less wear on fabrics.
Heating water is one of the largest energy draws in laundry. Washing with cold water (especially for everyday items) can dramatically lower your laundry footprint while still cleaning well—particularly when paired with a quality detergent and proper cycle selection.
If you’re choosing a washer, look for a high-efficiency model. Day to day, aim for full loads to maximize water and energy efficiency, but avoid overfilling so clothes can move and rinse properly. That prevents rewashing and reduces lint and fiber shedding.
Overdosing detergent can leave residue, require extra rinsing, and shorten fabric life. Measure carefully and consider lower-waste options (like concentrated liquids or powders in recyclable packaging). Skip fragrance boosters and single-use pods if they add extra packaging or irritants you don’t need.
Line-drying or using a drying rack is typically the lowest-impact option. If using a dryer, clean the lint trap, use dryer balls to improve airflow, and avoid over-drying—small changes that cut electricity use and help clothes stay in better shape.

Wash synthetic items less often, choose colder and gentler cycles, and avoid high-heat drying that can increase shedding. Using a microfiber-catching laundry filter or bag can also help keep fibers out of waterways.
