Does Hot Water Shrink Clothes?

Hot water will cause shrinkage to clothes made from a variety of different fabrics. Fabrics that will shrink the most in hot water include 100% cotton, silk, wool, linen, and hemp

Clothes made from natural fibers tend to shrink more than clothing made from synthetic fibers. Garments made from synthetic fibers such as polyester (can you shrink polyester), nylon, and spandex are resistant to shrinkage. This is because synthetic fabrics are treated with a special chemical during production to make them shrink, wrinkle, and sometimes stain resistant. 

Heat has the potent ability to shrink clothes, so avoid washing your clothes in hot water or tumble drying them in high heat if you do not want shrinkage to occur.

Your best course of action to make sure your clothes don’t shrink when cleaning them is to take them to a dry cleaner instead. Learn how much dry cleaning costs and how long dry cleaning takes.

How To Shrink Clothes

If you are looking to make your clothes tighter or shrink them, the main thing you want to do is use heat. The hotter the environment the garment gets placed into, the more likely it is to shrink. 

The best way to shrink clothes is by using the washing machine on the hot water setting, paired with the dryer (learn how to use a dryer properly & how long does a dryer take) on tumble dry settings: tumble dry high & tumble dry medium (tumble dry low will not be hot enough.)

How To Wash Clothes

Sort your laundry into groups so that white clothes, colored clothes, and dark clothes are washed separately. Check the care labels before beginning to make sure there are no special care requirements. Use the right water temperature and cycle settings to wash your clothes. Choose the cold water and delicate cycle settings if you do not know which presets to use. Use the appropriate laundry detergent, and do not over-pour.

Once finished (how long does a washer take?), air dry your clothes by hanging or laying flat on a drying rack (line dry or dry flat.) Learn all the ways to dry your clothes without a dryer.

Different fabrics will shrink to a different degree when placed in hot water. 100% cotton may shrink up to 20% of its size if it is not pre-shrunk, whereas a garment made from polyester may not shrink at all. Check your garment’s care label to see what kind of fabric it is made from. As a general rule, natural fabrics will always shrink more than synthetic fabrics. 

Hot water shrinks clothes. Cold water does not shrink clothes. Heat is the main requirement to shrink any type of clothing.
