How to Remove Rust Stains on Clothes (Even Old Stains)

Rust stains look disastrous, but they don't necessarily mean your shirt, jeans, or favorite tablecloth is headed for the trash.

The trick is treating rust differently from an ordinary laundry stain. Don't reach automatically for chlorine bleach, and don't put the garment in the dryer until the stain is gone. Heat can make a stubborn stain harder to remove.

Start by checking the garment's care label. If the item is washable, try the methods below. For delicate fabrics, vintage clothing, or anything labeled dry-clean only, take it to a professional cleaner and point out the rust stain.

How to Remove Rust Stains From Clothes

For a small, fresh rust stain on a washable garment, start with lemon juice and salt.

1. Place the stained area on a clean white towel.
2. Apply lemon juice directly to the rust stain.
   
3. Sprinkle a small amount of salt over the wet area.
   
4. Gently work the mixture into the stain with your fingers. Don't aggressively scrub the fabric.
   
5. Let it sit briefly, checking the fabric periodically.
   
6. Rinse thoroughly with cool water.
   
7. Check the stain before washing.
   
8. If it has disappeared, wash the garment according to its care label.
   

Do not put the clothing in the dryer until you're sure the rust is gone.

If you can still see orange or brown discoloration, treat the stain again rather than drying the garment.

How to Remove Old Rust Stains From Clothes

Old rust stains can take more than one treatment. Start with the lemon-juice method above. After rinsing, inspect the stained area while the garment is still wet.

If the rust remains, repeat the treatment or use a commercial rust remover labeled as safe for the fabric you're treating. 

Follow the product directions exactly. More isn't necessarily better, and leaving a rust remover on longer than instructed can damage fabric.

Don't combine different stain-removing chemicals to make them work faster.

For an old stain that has already been through the dryer several times, removal may be more difficult. Be patient, and avoid increasingly harsh products that could remove the fabric along with the stain.

Removing Rust Stains From White Clothes

A rust spot on a white shirt can be especially conspicuous, but chlorine bleach isn't the solution. Chlorine bleach can react with iron and may intensify rust discoloration instead of removing it.

Instead, use lemon juice and salt or a laundry rust remover that's safe for the fabric. Rinse thoroughly and inspect the garment before washing.

Don't assume that because something is white, it can withstand any stain treatment. Learn how to wash white clothes.

Removing Rust Stains From Colored Clothes

With colored fabric, the goal is to remove the rust without taking the color with it. Before using any stain treatment, test it on an inconspicuous part of the garment—an inside seam is ideal.

If the fabric's color changes, stop.

For valuable, delicate, or non-colorfast clothing, professional cleaning may be the safer option.

Using a Commercial Rust Stain Remover

What NOT to Do With Rust-Stained Clothes

Rust is one of those stains where attacking it harder can make things worse.

Don't use chlorine bleach. It can react with iron deposits and worsen the discoloration.

Don't dry the garment until the stain is gone. Check it after treatment and washing first.

Don't vigorously scrub delicate fabric. You can damage the fibers without removing the rust.

Don't use a household rust remover unless the label specifically says it's suitable for fabric.

Don't mix stain-removing chemicals. Use one treatment at a time and follow its directions.

Why Do Rust Stains Appear on Clothes?

Sometimes the culprit is obvious: clothing rubbed against rusty metal. Other times rust-colored stains seem to appear after laundry day.

Possible sources include iron in the water, rusty plumbing, or components in a washing machine. If orange-brown stains repeatedly appear on different loads of previously unstained clothing, the problem may not be your laundry technique.

Investigate the source before sacrificing another load of clothes.

What If the Rust Stain Won't Come Out?

If you've treated and rinsed the garment several times and the rust still won't budge, stop before escalating to harsher chemicals.

For an inexpensive everyday garment, you can try a fabric-safe commercial rust remover according to its directions.

For delicate, expensive, sentimental, or dry-clean-only clothing, take the garment to a professional cleaner. Tell them it's a rust stain and describe anything you've already used.

Sometimes knowing when to stop experimenting is the best stain-removal technique of all.
