Dark spots occur more commonly from chemical sunscreens, but mineral ones can leave discoloration, she says.
Tinted sunscreens can stain towels, and cosmetics are common offenders when not removed completely before toweling off.
The products delivery method can also affect the chances of ruining towels.
However, this does not guarantee no bleaching, she says.
If using benzoyl peroxide, Jeffy says, I encourage white towels and bed linens.
Another option is to choose towels that are bleach-safe, which allows more color choices than plain white.
