Learn how to wash and dry men's swim trunks to keep them looking great. Simple steps for fabric care, avoiding damage, and extending their life.
Quick Answer
Rinse your swim trunks in cold water right after swimming, then hand wash with mild detergent and hang them to dry in the shade. Avoid the dryer and hot water to keep the fabric stretchy and the colors bright.
Why Proper Care Matters
Swim trunks are made from stretchy materials that can break down quickly if you use hot water or a tumble dryer. Chlorine, salt, and sand also wear down the fabric and elastics over time. A simple rinse after each wear removes these elements before they cause damage.
The tie at the waist and the velcro back pocket on many trunks are the first places to show wear. Gentle washing keeps these closures working and prevents the drawstring from fraying.
Common Mistakes to Avoid
One of the biggest mistakes is wringing out your trunks. Twisting the fabric stretches it out of shape and can break the fibers. Instead, press the water out gently with a towel.
Another mistake is leaving wet trunks in a gym bag or hamper. Damp fabric in a closed space develops mildew and odors quickly. Hang them up as soon as you can.
Step-by-Step Washing and Drying
- Rinse Immediately: After swimming, rinse your trunks in cold water to remove chlorine, salt, sand, and sunscreen. This is the most important step to prevent fabric damage and color fading. Rinsing right after swimming is the best thing you can do for your trunks.
- Hand Wash with Mild Detergent: Fill a basin with cold water and a small amount of mild detergent. Gently swish the trunks for a few minutes, paying attention to the waistband and any stained areas. Avoid using bleach or fabric softeners, as they can break down the elastic. If you must use a machine, put the trunks in a mesh laundry bag and use the gentle cycle with cold water.
- Rinse Thoroughly: Rinse the trunks in clean cold water until no soap suds remain. Soap residue can attract dirt and cause the fabric to feel stiff. A second rinse ensures no detergent is left behind.
- Press Out Water Gently: Lay the trunks on a clean towel and roll them up, pressing gently to absorb excess water. Do not wring or twist the fabric, as this can stretch it out of shape. Rolling in a towel is a safe way to remove water without damaging the fibers.
- Air Dry in the Shade: Hang the trunks to dry in a shaded, well-ventilated area. Avoid direct sunlight, which can fade colors, and do not use a tumble dryer, as the heat can shrink or warp the stretchy material. If you need them dry fast, use a fan or lay them flat in the shade.
