You use well water or live in a hard-water region
2. Benzoyl Peroxide (In Acne Products)
This is one of the biggest culprits.
Face washes, spot treatments, and body washes containing benzoyl peroxide bleach and oxidize fabric, leaving orange or rust-colored patches.
Signs this is your issue:
Towels used after washing your face show more staining
Pillowcases or shirts also show orange or bleached-looking spots
Spots are in areas that touch skin
3. Makeup Residue
Foundations, self-tanners, bronzers, and some blushes contain pigments (especially iron oxides) that cling to fabric fibers—even after washing.
Signs this is your issue:
You dry your face on towels after applying or removing makeup
Towels used in bathrooms with humid, makeup-filled air stain faster
Stains look like smudges or finger wipes
