Why Towels Develop Orange Stains
Orange stains on towels typically come from minerals, rust, or residue buildup during washing. Here are the most common causes.
1. Rust in Your Water Supply
One of the biggest culprits is iron in your water. When iron is exposed to oxygen, it oxidizes and forms rust particles. These particles can attach to fabric fibers and create orange or reddish-brown stains.
Homes that rely on well water are especially likely to experience this issue.
2. Hard Water Mineral Buildup
Hard water contains minerals such as:
Iron
Calcium
Magnesium
Manganese
Over time, these minerals build up in towel fibers. This buildup can react with detergent and heat, producing orange or rusty stains that resist normal washing.
3. Too Much Detergent or Fabric Softener
Using excessive detergent may seem like a good idea for cleaner laundry, but it can actually make stains worse.
Extra detergent or fabric softener can:
Trap minerals inside fabric fibers
