Quick answer

A white shirt turning orange is usually rust: iron in your water supply, old pipes or a rusting washer drum leaves orange-brown stains on light fabric. Find where the rust comes from, then lift the stain with lemon and salt or a laundry rust stain remover made for fabric. Never use chlorine bleach on rust, because it can set the stain.

Free fix vs. permanent fix

Free fix · 20 minutes plus drying

Lemon juice, salt and sun

  • Wet the stained spot and cover it with salt
  • Squeeze lemon juice over the salt
  • Lay it in the sun for an hour
  • Rinse and check the stain before you dry the shirt

How long it lasts: Fades light, fresh spots. Set-in rust, or rust that keeps coming from your water, comes back.

A laundry rust stain remover

Rust removers made for fabric dissolve the iron compounds that make the orange color instead of bleaching them. They work where lemon and salt only fade the mark, and they are made to be safe on white cotton when you follow the label.

What to get: Laundry rust stain remover

How long it lasts: Lifts old and new rust stains well. The stain stays out as long as the source is fixed.

Why it happens

1

Rust in the water supply

Old iron or galvanized pipes shed rust, and work on the water main can stir up sediment. The orange tint shows on white cotton first.

2

Iron in well water

Dissolved iron is clear in the glass but turns orange when it meets air or bleach. It leaves rust-colored marks on whites wash after wash.

3

A corroding water heater

If only the hot tap runs orange, the rust is likely coming from inside the water heater tank.

4

A rusty washer drum or metal in the load

A chipped drum or agitator coating, and loose metal such as bobby pins and buttons, can shed rust onto wet clothes.

Do these in order, starting with the simplest.

  1. Find the source

    Tool used: White bowl or bucket

    Run cold water for a full minute into a white bowl, then do the hot tap. Orange or brown in both means rusty pipes or well iron. Only in the hot means the water heater. If the water is clear, look inside the washer drum for chipped or rusty spots.

  2. Do not dry the shirt or use chlorine bleach

    Heat sets rust into the fibers, and chlorine bleach can turn dissolved iron into darker, permanent stain. Keep the shirt wet until you treat it.

  3. Treat light spots with lemon and salt

    Tool used: Lemon and salt

    Wet the spot, cover it with salt, squeeze lemon juice on top and lay it in the sun for an hour. Rinse well and check.

  4. Use a rust remover for what is left

    Tool used: Laundry rust stain remover

    Mix the remover as the label says in a plastic or glass container and soak or dab the stain for the time listed. Work it in with the toothbrush if the label allows. Rinse thoroughly.

  5. Wash and check before drying

    Wash the shirt in the machine on a normal cycle, then check it in daylight. If any orange remains, treat it again before the dryer.

When free fixes aren't enough

Lemon and salt fade only fresh, light rust. If the orange returns after every wash, the source is still in your water or your machine, and treating shirts will never catch up. If both taps run orange, call your water utility or a plumber. If only the hot tap does, the water heater tank may be corroding and need a flush or an anode check. On well water, a water test shows how much iron you have. A rust remover fixes the stain. The source needs its own fix.

Where the orange comes from, and what fixes it

  • Both taps orange: rusty pipes or supply. Run the cold tap a few minutes before laundry and call the utility if it persists.
  • Only hot orange: water heater. Flush the tank or call a plumber about the anode rod.
  • Well water: iron. Test the water and ask about an iron filter.
  • Clear water: the washer drum or metal in the load. Inspect the drum and keep metal out of pockets.

What to skip

Chlorine bleach on rust

Chlorine bleach can react with the iron and turn the stain darker and permanent. Skip it for orange spots. Skip the dryer too, until the stain is gone.

Frequently asked questions

Why are my white clothes turning orange after washing?
The usual cause is rust or iron in the water, or rust shed from the washer drum. Colors hide it and whites show it. Check the tap water in a white bowl and look inside the drum.
Does vinegar remove rust from clothes?
It can lift a light, fresh rust spot if you soak the fabric for about 30 minutes, but it is weaker than a rust remover. Test colored fabric first.
How can I tell if it is the washer or the water?
Check the tap water in a white bowl, hot and cold. If it is clear, wash a clean white rag alone. If it comes out orange, look for chipped or rusty spots in the drum.
Will the stain wash out on its own?
Not usually. Rust sticks to fibers. Normal detergent does little, and heat from the dryer sets it. Treat it while it is wet.
