UV protection clothing is becoming an increasingly popular choice among outdoor enthusiasts, athletes, and parents who want to keep their skin safe from harmful sun exposure. These special materials are made with densely woven or chemically treated fibers that block a portion of UV rays, helping to prevent burns and long-term skin damage. However, to maintain their protective properties, UV clothing requires special care.

This guide provides comprehensive advice on how to wash, dry, store, and use UV garments so they stay effective and last longer.

What is UV Protection Clothing and How Does It Work?

UV protection clothing is specifically designed to reduce the amount of UV radiation reaching the skin. Its effectiveness is indicated by the UPF (Ultraviolet Protection Factor) rating; for example, UPF 30 means only 1/30th of UV radiation passes through. These fabrics are usually made of polyester, nylon, spandex, or blends with natural fibers, and some garments are additionally treated with UV-repellent agents.

Over time, improper care—like aggressive washing or drying in direct sunlight—can significantly reduce the protective capability.

Washing UV Clothing – Basic Rules

When washing UV protection clothing, it’s important to understand that harsh detergents, bleach, and fabric softeners can damage fibers and reduce UV resistance. It is recommended to use mild detergents without added fragrances or optical brighteners. Hand washing in cold water is the gentlest way to care for these garments. If you prefer machine washing, always select a delicate cycle and low temperatures.

Before washing, always check the care label—some items require specific handling.

Drying and Preserving Protective Properties

UV clothing should be dried in the shade or in a well-ventilated area away from direct sunlight. Sun exposure can fade colors and gradually reduce the effectiveness of the protective layer. Never use a tumble dryer, as high heat can permanently damage the fibers.

Once dry, store your UV garments in a dry, dark place. Folding is preferable to hanging, as this prevents stretching.

Ironing and Reapplying Treatments

Most UV garments don’t need ironing. If you do need to remove wrinkles, iron on the lowest heat setting without steam, and always use a pressing cloth between the iron and the fabric.

Certain UV-treated fabrics can have their protective layer refreshed with special re-impregnation sprays available in specialist stores. Always follow the manufacturer’s instructions when using these products.

Frequently Asked Questions

How long does UV protection in clothing last?
It depends on how often the garment is used and how it’s cared for. On average, after about 40–50 washes, the protection level may start to decline.

Can I wash UV clothing in a washing machine?
Yes, but only on a delicate cycle with mild detergent and without fabric softener.

Does UV clothing also protect against heat?
To some extent—densely woven fibers can help block heat, but their main function is UV protection.

Does hand washing preserve UV protection better?
Yes—hand washing is less abrasive and helps maintain the integrity of the fibers longer.

Practical Tips for Longer Lifespan

Always rinse UV clothing after exposure to salt water or chlorinated pools. Salt and chemicals damage fibers and reduce UV protection. After rinsing, gently squeeze out excess water and air dry.

Avoid leaving wet garments in bags for extended periods, as moisture encourages bacteria and accelerates material degradation.

If you notice the fabric becoming thin or stretched, it’s a sign that its protective qualities are fading.

When Is It Time to Replace UV Clothing?

Even with the best care, UV clothing has a limited lifespan. If a garment is more than two to three seasons old, the color is faded, or the material is visibly worn out, it’s time to replace it to ensure you’re still getting effective protection.

UV protection clothing is an excellent ally in keeping your skin healthy. But its effectiveness depends greatly on how you wash, dry, and store it. Careful maintenance prolongs its life, preserves functionality, and ensures you continue to benefit from reliable protection.
