It started with a small orange mark—barely visible at first—on my favorite gray towel. I tried everything: scrubbing, soaking, changing detergents, even deep-cleaning the washer. But soon, more spots appeared, bright and stubborn, until my towels looked as though someone had splattered them with orange paint. Frustrated, I blamed the water, the detergent, even the dryer. When I finally looked closer, I discovered a surprising truth that changed how I think about towels, skincare, and water quality altogether.
Those orange marks weren’t stains at all—they were areas of color loss. One of the main causes is a common ingredient in many acne treatments: benzoyl peroxide. Found in creams, gels, and cleansers, this ingredient can bleach fabric dyes on contact. When it touches towels, pillowcases, or clothing, it strips color completely, leaving behind orange or yellow patches that can’t be washed away. Even freshly laundered towels may show new marks if they come into contact with skincare or hair products containing peroxide.
But benzoyl peroxide isn’t the only possible cause. Tap water with high iron content can leave rusty discoloration that worsens when exposed to heat from the dryer. Hair dyes, self-tanners, and pigmented shampoos may also leave faint tints that become visible once the fabric dries. Even some household cleaning sprays can contain mild bleaching agents that, when splashed, create similar marks over time. Once I understood how many everyday items could contribute, I realized my “mystery stains” were really a simple chemical reaction.
Now, a few small habits keep my towels looking fresh. I use white towels when applying skincare, wait until products are fully absorbed before getting dressed, and installed a water filter to reduce iron levels. Towels that already have marks get reused for cleaning or dyed darker for a second life. What began as a frustrating mystery became a reminder that a little awareness can make a big difference. The next time you spot an orange mark, don’t worry—it’s not a stain, it’s science, and it’s easy to manage with a few thoughtful steps.
