Orange and Brown Stains on Towels
Those brown or orange stains are probably not rust. They are usually caused by make-up, acne medicine, sunscreen, or self-tanners, especially on beach towels.
Why do bath towels get discolored?
Hard water contains extra minerals that towels absorb. These mineral deposits are difficult to wash out and can build up even more over time. The mineral buildups can lead to discolored spots on your towels.
How do I stop my towels from discoloring?
Apply white vinegar to the wash water at the first wash cycle. White vinegar set the color of the towel, prevents it from fading, removes detergent residue, and eliminates its bad odor. Never use brightening products that are used for white towels.
