While we recommend home-laundering, since it is an effective way of reducing the environmental impact throughout a shirt’s lifecycle, and ensure that your shirt looks its best, we are aware that many of you may prefer going to a professional cleaners. If so, to make a smarter choice for the planet, choose a green dry cleaning service in your area (also referred to as non-toxic dry cleaning). Dry cleaning is a chemical process: in a green dry-cleaning process, they use liquid CO2 or silicone-based solvents, meaning you contribute to reducing the use of chemicals like Perc, harmful to both planet and people.
