Learning how to wash and reshape sweaters at home can help you avoid dry-cleaning costs. With a bit of time and patience, your sweaters can look great, smell fresh and feel soft to the touch.
Sweaters that are knit from cotton, acrylic, ramie, bamboo, wool and even cashmere yarns can be cleaned at home. The exception is any sweater than interior shaping for lapels, collars and shoulders. While the outer fibers may be washable, the interior shaping materials (interfacings) may be dry clean only materials. Washing these materials can make them go limp and loose their shape. However, you may be able to clean and freshen these dry clean only sweaters at home with a home dry cleaning method.
Machine Washing Tips for Sweaters
Some basic sweaters may have a label that says they can be machine-washed. This is usually true for acrylic and man-made fibers. Some cotton and ramie sweaters may also allow machine washing but you will have less success with these fibers because they tend to shrink or stretch more easily than man-made fibers. When you machine wash, there are still some tips that will keep the sweaters looking their best by reducing stretching or shrinking and pilling.
Pretreat all stains before washing.
Use the lowest water temperature possible when washing sweaters.
Use the gentle/permanent press cycle when washing knits.
Stop the machine before the spin cycle. A high revolution spin cycle can be stressful to the yarns and pull them out of shape. Take care not to pull the sweater out of shape as you remove it from the washer.
Use mesh laundry bags (one sweater per bag). Mesh bags contain and protect sweaters and are easy to fish out of the washer. Less abrasion from other garments will reduce pilling.
One special tip to remember: Never put a sweater into the clothes dryer! Avoid the dryer to prevent shrinking and excessive static cling with acrylic fibers.
Hand Washing Tips for Sweaters
Hand washing is usually the safest choice for washing natural fibers as you can see from this About.com Video. If there are stains, pretreat before washing. Use a gentle detergent or homemade wool wash following the label directions. Here are some additional tips:
Do not use too much detergent or you will have a very difficult time getting out all of the suds. Left-in detergent can cause fibers to feel stiff and scratchy.
Use cold or lukewarm water - never hot - for best results.
Gently agitate or squeeze the sweater in the water to be sure that the detergent and water reach all parts of the sweater. Never wring or scrub which can cause stretching and pilling.
Support the sweater from underneath as you move it to the rinse water or transfer it to towel for drying.
It is best to wash only one sweater at a time. Overcrowding the sink or wash basin can prevent soil from being removed.
Never mix colors when washing! You may have fading that is very hard to remove.
Reshaping and Drying Sweaters
Here are the steps the best method to dry and reshape sweaters unless you own a ventilated drying rack for sweaters:
Gently remove excess water and supporting the sweater, lay sweater flat on a dry, heavy absorbent towel and roll the sweater in the towel, pressing firmly as you roll. Do not wring the towel.
Next, lay another dry bath towel on a flat surface large enough to hold your sweater with arms extended. A card table is the perfect size for air-drying sweaters and typically has a protective vinyl top. Always protect wood surfaces with a vinyl tablecloth under the towel.
Place the sweater on the dry towel and reshape the sweater into its original shape. Pat the sweater into shape; avoid tugging or pulling. Gently push the ribbing together at the neckline, wrists and waist. Fasten buttons. Fold collar as it would be worn. If the sweater has an attached belt, extend it flat away from the sweater on each side. For removable belts, dry the belt off the sweater.
Allow the sweater to dry for 24 hours.
Flip the sweater over onto a new dry towel, arrange into shape (the shape will have set by now but you don’t want to add wrinkles or slow drying) and dry for another 24 hours.
Fold your sweater and put it away. Never hang a knitted garment. The weight will stretch out the shoulders very quickly.
