Each time you put your nylon garments through the washing machine, you are bringing them one step closer to the end of their useful life. Of course, that’s true of all garments, but the clock moves a little faster with nylon.
With this in mind, do your best to avoid unnecessary wash cycles. For instance, you might decide to wash your nylon items by hand when you have time, saving trips through the laundry machine for occasions when you are in a hurry. Even if you only hand wash half the time, that reduction in trips through the machine can help to extend the life of your garments.
