Those strange pale or orange spots on your towels can be confusing at first, especially when they seem to appear out of nowhere. In most cases, the culprit is benzoyl peroxide—a common ingredient in acne treatments from brands like PanOxyl, Clearasil, or Neutrogena. While effective at treating breakouts, this ingredient acts as a strong oxidizer, meaning it can bleach fabrics on contact, similar to household chlorine bleach.
On dark-colored towels—black, navy, or deep gray—the effect is even more noticeable. Instead of turning white, the fibers take on shades of orange, yellow, or even pink. This happens because dark dyes break down more quickly, revealing the lighter underlying pigment. A simple way to identify the issue: if the spot is lighter than the surrounding fabric, it’s likely bleaching; if it’s darker, it’s probably a normal stain.
Unfortunately, once this type of damage occurs, it’s permanent. The color isn’t just stained—it’s chemically removed from the fibers. Washing, scrubbing, or soaking won’t restore the original shade. In some cases, leftover residue from these products can transfer during washing and affect other items if laundered together.
To prevent this problem, a few simple adjustments can help. Use white towels for your face, rinse thoroughly after applying acne treatments, or switch to alternatives like salicylic acid to protect your fabrics. And if a towel is already affected, it doesn’t need to be thrown away—it can still serve as a cleaning or gym towel. Understanding the cause is often the best way to avoid repeated frustration.
