Polyester is one of the most common fibers in clothing, and it is generally forgiving. Most polyester items can be machine washed, dry quickly and need little ironing. The details below help you avoid the usual problems.
Quick care summary
- Check the care label first, since polyester is often blended with other fibers.
- Wash in cool to lukewarm water on a normal or gentle cycle.
- Turn items inside out and avoid washing with rough items.
- Air dry, or use low heat if you must tumble dry.
- Iron on a low setting, if at all.
Is polyester easy to keep clean?
Generally, yes. Polyester does not absorb much water, so it dries quickly and usually resists wrinkling and shrinking better than many natural fibers. It can, however, hold on to oils and odors, and it can pick up lint and develop pilling. Washing it regularly and not overloading the machine helps.
Washing polyester step by step
- Read the label. Blends, such as polyester with cotton, wool or elastane, may need different care.
- Sort. Wash with similar weights and colors. Avoid heavy or abrasive items such as denim, towels or anything with exposed zips.
- Turn inside out. This protects the outer surface from rubbing.
- Choose a temperature. Sources commonly recommend cool or lukewarm water, in the region of 30 to 40 degrees Celsius. Some retailers say 40 degrees is fine. Hotter washes are not usually needed.
- Pick a cycle. A normal or gentle cycle works for most items.
- Remove promptly to reduce creasing.
What detergent should you use?
Polyester does not need a special detergent. A mild liquid detergent is a common recommendation and works for most items. Liquid detergents often dissolve more easily in cool water. For oily stains, a pre-treatment may help, since polyester tends to hold on to oil. Always test a stain remover on a hidden spot.
Can polyester shrink in the wash?
It is not very prone to shrinking, but it can happen, particularly with high heat or in blends containing natural fibers such as cotton. Synthetic fibers can also be damaged or distorted by very hot water or a hot dryer. Keeping temperatures moderate is the safest approach.
Drying polyester
Polyester dries fast on a line or rack, which also saves energy and reduces creasing. If using a dryer, choose a low heat setting and take items out when they are just dry. Heat can cause lasting creases or damage the fibers.
Ironing and wrinkles
Pure polyester often does not need ironing. If it does, use a low setting (one retailer suggests up to about 110 degrees Celsius), iron on the reverse side or use a pressing cloth. Steaming is a gentle alternative. Always check the label, since blends may behave differently.
Odors and pilling
- Odors. Polyester can hold onto smells. Wash soon after wearing, avoid overloading and make sure items dry fully.
- Pilling. Rubbing causes small balls of fiber to form. Washing inside out, using a gentle cycle and avoiding abrasive items reduces it. A fabric shaver can remove existing pills.
Shedding microfibers
Synthetic fabrics can release tiny fibers when washed. Researchers are still studying how best to reduce this, but common suggestions include washing less often, using full loads at lower temperatures, and using a laundry bag or filter designed to catch fibers. Keeping clothes in use longer is also helpful, as discussed in our fabric care guide.
Polyester or 100% cotton?
Neither is better in every case. Polyester is typically durable, quick drying and low maintenance. Cotton is a natural fiber that many people find comfortable and breathable. Polyester is made from petroleum-based materials and is not readily biodegradable, while cotton and other natural fibers generally are. See is wool biodegradable for how natural fibers compare, or vegan clothing fabrics for synthetic and plant-based options.
If you sew with polyester
Prewash polyester fabric before cutting, test your iron on a scrap, and use a needle suited to synthetics. Slippery weaves can be tricky to cut, so a rotary cutter and plenty of pins or clips may help. Keep a note of the fiber content so you can care for the finished item correctly.
