Tiny traces of the chemical remain on your skin—and transfer to the towel.
Over time, repeated exposure removes dye from the fibers.
Result: A permanent, sunburst-like bleach mark—often yellowish-orange, especially on grey, black, or navy towels.
Fun fact: The orange tint comes from how light reflects off the damaged fibers—not an added color.
What You Can Do:
Use old or white towels after applying acne treatments.
Wash your face and wait 5–10 minutes before drying—let the product fully absorb.
Switch to salicylic acid or niacinamide if you want gentler options for fabrics.
Label your “treatment towels” so they don’t mix with the rest.
Once bleached, the damage is permanent—but prevention works fast.
#2: Rust & Iron in Your Water
If you have well water—or even city water with high mineral content—iron and rust could be staining your laundry.
Unlike benzoyl peroxide, which removes color, iron adds it—depositing reddish-orange specks on damp towels, pillowcases, and whites.
Signs it’s iron:
Spots appear mostly on the bottom or folded edges (where moisture lingers)
You notice similar stains in sinks, showers, or dishware
Your water has a metallic smell or leaves red-brown residue
Over time, oxygen turns dissolved iron into rust particles that bind tightly to fabric—especially when combined with chlorine or heat.

What You Can Do:
Install a water softener or iron filter — long-term solution for homes with hard water.
Use iron-removal laundry additives like Iron Out or Whink Rust Stain Remover (follow instructions carefully).
Avoid chlorine bleach — it can make iron stains worse by oxidizing them further.
Rinse towels quickly after use — don’t leave damp towels sitting in humid bathrooms.
Pro tip: If you have well water, get it tested. High iron levels aren’t harmful to drink (for most), but they’ll wreck your linens.
#3: Sun Fading + Sweat Buildup
Sunlight breaks down dyes over time—especially on towels hung outside to dry.
But combine UV exposure with sweat, body oils, and deodorant, and you get something sneaky:
Yellow-orange discoloration along folds or edges—not quite a stain, not quite fading.
This is especially common with white or light-colored towels.
Sweat contains salts and proteins that react with fabric over time, while sunscreen or self-tanners can also transfer onto towels and oxidize in sunlight.
