The life span of a T-shirt is probably not as long as you think it is―or wish it were. Once a tee goes through one, maybe two, summers, it's ready for under-sweater-only status. But a few simple tricks will help keep it as white and shapely as possible.
- Most T-shirt manufacturers recommend washing in cold water, yet according to Jane Rising, a manager at the International Fabricare Institute, detergents function better at higher water temperatures. So if you dare challenge the label: Wash in warm water; hot water can cause shrinkage. Use the permanent-press cycle for drying.
- Use fabric softener to avoid wrinkles, and remove clothes as soon as the dryer shuts off.
- To keep whites whiter, don't overload the washing machine. Put in only whites―no prints or pastels. (Source: realsimple)
