Why the Spots Turn Orange
On dark towels—think navy, charcoal, or black—the bleaching process often reveals bright orange, yellow, or pinkish hues. These are the base colors of the dye left behind after the darker pigments are stripped away.
A simple way to tell:
- Lighter-than-usual spots: bleach marks
- Darker spots: regular stains
Why These Marks Won’t Come Out
Once the color is gone, it’s gone for good. No scrubbing or fancy detergent can restore the original shade.
Washing these towels with other fabrics can even spread residual bleach, causing more accidental discoloration.
Other Possible Causes
Though benzoyl peroxide is usually to blame, a couple of other factors can create similar marks:
- Rust in Water: Old pipes or iron-rich well water can leave reddish-brown streaks on laundry. This affects all items, not just your face towels.
- Serratia Marcescens: This bacteria grows in damp bathrooms and appears as a pink or orange slimy film. Unlike bleach marks, it can usually be cleaned off with disinfectant or bleach.
