I decided to stop washing my clothes so much. I had gotten in the habit of just throwing items in the hamper. Questionable item? Toss it. Change shirts halfway through the day? Toss it. I'm sorry but a 'day at the office' does not necessitate a thorough wash with heavy duty laundry detergent. Socks and underwear--sure, they only get a single use. But my pants and shirts can be worn 2, 3 and even more times with impunity. I simply hang them up in my room, and the air over the course of a few days freshens them (not that they need it) for my next use. A little spritzing with an iron brings them back to life.
Its a total win-win-win-win. I'm spending less money on detergent and the laundramat. I'm conserving energy (when I do wash clothes, I am careful to hang them up to dry and avoid using dryers). I'm flushing less detergents into the environment (and using biodegradable ones). I am spending less time at the laundry machines and more time doing whatever else I'd prefer. The best part of it all is that I have experienced no loss of quality of my lifestyle whatsoever, only improvements.
I don't know why, but many of us are programmed to wash clothes obsessively. A single use for part of a day and the item gets tossed into the hamper. Its unnecessary and wasteful. We use much more detergent per load than necessary, and wash many more times than reason would dictate. And we never allow ourselves that nice feel of a pair of jeans that have loosened up after several days wear to really become part of your body, to live and breathe with you as a good companion, rather than the starched floor model we don't know and keep at a distance.
