Best Way to take care of your Garments
Always wash your sweaters with cold water to preserve their shape. When it comes to machine washing, cold water temperature trumps over all other cycle selections. Be aware that some machine washers have certain factory cycle settings for water temperature. While others give you the option of configuring the temperature separate of cycle type and duration.
The distinction in cycle types rests primarily in the speed at which the drum agitates whatever is being washed. It is best that you do not agitate your sweaters as much as possible, which is why choosing the cycle labeled "delicate" or "hand wash" is best. These cycles may also be expressed as "slow/slow"— defined as both the wash and the spin cycles are performed at the slowest speed.
If your washer/dryer machine offers a choice of cycle duration, select the shortest available option. Some machines express time in actual minutes (usually 4-15), while some use the far less transparent terms like "light", "normal", "heavy", or "super heavy". Always select the least amount of minutes or "light".
Using a mesh laundering bag will help to cut down on the amount of friction the sweater is exposed to. It's also best to wash the sweater alongside other delicate items and avoid putting it in the machine with heavy, bulky items like jeans, sweatshirts, and towels, which can rough-up more delicate clothes.
If possible, air dry is preferred. Don't use the air dry setting on the dryer—too much friction. Lay the sweater flat (hanging can cause the wet fibers to stretch) and let it air dry. You can speed things along by placing it near an open window, fan, or dehumidifier.
