🧺 Why Towels Develop Orange Stains and How to Prevent Them

💧 2. Sources of the Iron and Minerals

Understanding where the iron comes from can help prevent it:

1. Tap water

   • Older pipes, especially iron or galvanized steel, leach small amounts of iron into water.

   • Water softeners do not always remove iron completely.

2. Washing machines

   • Rust in the drum or water inlet valves can transfer directly to fabric.

   • Over time, the repeated cycles oxidize and leave deposits.

3. Iron in detergents or fabric softeners

   • Some powdered detergents contain trace iron.

   • Iron interacts with oxidizing agents in bleach, producing orange stains.

4. Environment

   • Storage in a damp, humid area encourages oxidation.

   • If towels remain wet in piles, the oxidation process accelerates.
