Old washing machines are inefficient with both water and energy. When shopping for a new machine, look for the energy star certification to reduce your water and energy usage. Choose a front-facing washer, especially for washing synthetic materials (such as fleece, polyester or spandex). These garments release microscopic plastic fibers into the waterways. Top-loading machines release 6-7 times the number of the microfibers as front-facing machines.
To be as environmentally-friendly as possible, skip the dryer completely and use a clothesline or drying rack instead.
Certain fabrics such as wool, lace, cashmere or silk may need to be hand washed.
Before first wear
To prevent dark dyes from bleeding, wash your jeans before wearing them. Add 1/2 cup of white vinegar to the water during the first wash to set the dye.
Wash your jeans only once or twice a month - as infrequently as possible. Use a mild soap and a damp cloth or a toothbrush to remove small stains. Machine wash cold with a detergent formulated for cold temperatures for best results.
Air dry flat to retain shape. Drying can shrink your jeans and warp the fabric. Only use a dryer to shrink your jeans.
If using a dryer, dry on low heat for 20 minutes maximum and then air dry the rest of the way.
