🧪 Special casesHow to remove sunscreen stains

Orange stains after washing · the culprit is iron in the water

White clothes worn on a day you applied sunscreen sometimes come out of the wash with orange or brown stains. This is reported to happen when some UV filters (such as avobenzone) meet iron ions in tap water and form colored compounds. Treatment differs between an oily stain before washing and an orange stain after washing.

🔬 Why this order works

Before washing, it's an oil stain, so dish soap will get it out. If it turns orange after washing, it's a stain with metal (iron) in it, so you need an acid (citric acid or vinegar) to dissolve rust. Chlorine bleach can make this stain darker.

🧺 Step by step

Tap a step when it's done to tick it off.

👕 By fabric

⚪ White cotton & linen

Repeat the citric acid soak. A commercial rust remover (for fabrics) can also be used, but follow its directions carefully. No chlorine bleach.

🎨 Colors & synthetics

Acid can discolor some dyes, so test on the inside before using.

🧶 Wool, silk & cashmere

Even acid treatment is hard on wool and silk. Tell the dry cleaner it's a sunscreen stain.

🚫 Don't

  • Chlorine bleach — it makes stains with iron in them darker.
  • Mixing citric acid or vinegar with chlorine bleach in the same water — it releases toxic gas.

⏳ If it has already dried

Orange stains that have been through several washes often fade with acid treatment too, but you may need to repeat it several times.

💡 Tip

Get dressed only after sunscreen has fully absorbed, and before putting sunscreen-stained white clothes in the machine, rub the collar and cuffs once with dish soap; this helps prevent orange stains.

❓ Common questions

Does every sunscreen cause orange stains?

They're mainly reported with organic (chemical) sunscreens containing ingredients like avobenzone. Mineral sunscreens that use only zinc oxide or titanium dioxide may leave white oily marks, but orange stains are fairly rare.

Can it happen to rash guards and swimsuits?

Yes, it can. After swimming, rinse right away in cold water and hand-wash with liquid detergent. Always test swimsuits on the inside before any acid treatment.
