How to Care for Sun Bum Apparel: Washing Tips for UPF Protection Longevity

Sun Bum apparel is built for the beach, but its UPF rating only lasts as long as you care for it properly. Saltwater, chlorine, sunscreen oils, and even regular wear can break down the fabric’s UV-blocking fibers over time. The good news: a few simple washing habits can help your favorite rash guard, cover-up, or swim trunks keep their protective edge for many sunny days ahead.

Whether you’ve just picked up a new UPF shirt or you’re trying to extend the life of an old favorite, these care routines are easy to follow. And because your beach-day gear works best as a system, we’ll also point you toward complementary Sun Bum products that make the whole routine smoother.

Why UPF Clothing Needs Special Care

UPF (Ultraviolet Protection Factor) is a physical property of the fabric weave and any added UV absorbers. When the fabric stretches, fades, or accumulates residues from sunscreen and salt, those gaps allow more UV rays to pass through. Harsh detergents, bleach, and fabric softeners can strip the UV-blocking finishes or relax the tight weave. That’s why treating your Sun Bum apparel gently is not just about color—it’s about keeping the protection you paid for.

Think of it like this: you wouldn’t use a rough scrub on a delicate face sunscreen. The same logic applies here. Gentle handling and the right products preserve the integrity of the fabric, so your skin stays shielded.

• Always check the care tag inside your apparel for specific temperature and wash-cycle instructions.

6 Washing Tips to Maximize UPF Longevity

1. Wash before first wear. New garments often have finishing chemicals that can temporarily reduce UPF. A gentle pre-wash in cold water wakes up the fabric’s protective qualities. 2. Turn garments inside out. This reduces friction on the outer surface where UV absorbers are applied. 3. Use a mild, liquid detergent. Powders can leave residue that blocks the fabric’s breathability and degrades UPF over time. Avoid bleach and fabric softener—they are the top enemies of UV protection.

4. Wash in cold water on a gentle cycle. Hot water accelerates fading and can shrink the weave, reducing coverage. 5. Air dry only. High heat from dryers destroys the elastic fibers and UV finishes. Hang your Sun Bum apparel in the shade to prevent sun damage while drying. 6. Never wring or twist. Roll the item in a towel to remove excess water instead. This keeps the fibers aligned and the UPF uniform.

• For items like the SB x Kitsch Limited Edition Scrunchie Set, follow the same gentle rules—machine wash cold in a lingerie bag and air dry to keep the elastic snug and the print vibrant.



• If you use sunscreen before dressing, let it absorb fully into your skin for a few minutes to avoid transferring heavy oils onto the fabric.

Storage and Everyday Habits That Help

How you store your UPF apparel matters just as much as how you wash it. Keep rash guards and swim shirts folded loosely rather than stuffed into a drawer. Hanging them on thick, padded hangers prevents stretching at the shoulders. And when you’re at the beach, avoid sitting directly on rough surfaces like concrete or sandpaper-like towels—abrasion wears down the weave faster than anything else.

A smart beach-day routine also includes reapplying sunscreen on your face and lips. The Original SPF 30 Sunscreen Lip Balm 3-Pack is an easy way to keep your lips protected without worrying about sticky residue on your collar. By pairing good clothing care with full-body sun protection, you get the most out of every Sun Bum product in your bag.

Treat your Sun Bum apparel with the same respect you give your skin—gentle, consistent care keeps both performing at their best. Wash cold, air dry, and skip the softeners. With these habits, your UPF gear will stay protective and comfortable for many seasons of sunshine.
