Orange Stains on Towels? Here’s What Causes Them and What Works

A frequent cause of unusual orange or pale marks on towels is benzoyl peroxide, a chemical commonly used to treat acne. It’s found in products like PanOxyl, Clearasil, and Neutrogena, as well as some prescription creams. While effective on skin, it behaves like a bleaching agent on fabrics.

When it comes into contact with darker towels—such as black, navy, or charcoal—it can strip away color. This process often leaves behind orange, yellow, or pinkish patches as the darker dyes break down first.

A simple way to identify the issue is by observing the mark. If it appears lighter than the surrounding fabric, it’s most likely caused by bleaching. If the spot is darker, then it’s probably a standard stain instead.

Unfortunately, these discolorations are permanent. Since the fabric’s dye has been chemically removed, no amount of washing or scrubbing can restore the original color.

There’s also a risk of spreading damage. Residue left on towels can transfer during washing and affect other clothes, causing similar fading or discoloration.

Although benzoyl peroxide is the most common cause, other factors may be involved. Rust from aging pipes can leave reddish-brown marks, while bacteria like Serratia marcescens can create a pink film that usually wipes away.

To avoid this problem, consider using white towels for your face, rinsing skin thoroughly after applying acne treatments, or switching to alternatives such as salicylic acid. Damaged towels can still be reused as cleaning cloths or for workouts.
