How to maintain the effectiveness of UV-blocking clothing?

April 5, 2026

Quick Answer

To maintain the effectiveness of UV-blocking clothing, it's essential to follow a specific laundry routine, avoiding harsh chemicals and high heat. Washing and drying in cold water, and line-drying when possible, can preserve the fabric's UPF rating. Regularly checking for tears and reinforcing weak areas is also crucial.

Scent-Free Laundry Techniques

When washing UV-blocking clothing, it’s vital to use a scent-free laundry detergent to prevent chemical residues from compromising the fabric’s UPF rating. A good rule of thumb is to use a detergent specifically designed for washing outdoor gear or activewear. Avoid using fabric softeners, as they can reduce the fabric’s breathability and UPF protection. Instead, opt for a fabric refresher or a UV-blocking treatment to maintain the fabric’s performance.

Drying and Storage Best Practices

After washing, it’s essential to dry UV-blocking clothing in a way that maintains its UPF rating. Line-drying or tumble-drying on a low heat setting (below 140°F or 60°C) can help preserve the fabric’s performance. When storing UV-blocking clothing, avoid folding or creasing the fabric, as this can weaken the UPF protection. Instead, hang the clothing on a breathable hook or in a mesh bag to allow for airflow and prevent moisture buildup.
