# How to Remove Rust Stains from Clothes, by Fabric > Rust stains on clothes, routed by fabric: which rust remover each fabric can take, the lemon-and-salt limits, and why chlorine bleach sets rust. **Published :** 2026-09-29 --- **Summary:** Never use **chlorine bleach** on rust: it sets the stain. On white or colourfast washables, use a **commercial rust remover** after a hidden-area test. Lemon juice, salt and sun is an option, but lemon juice and sunlight can both bleach colours. A dry-clean-only garment goes to a dry cleaner. The table routes each fabric to the removers it can take, and each cell names its source. Rust stains may be very difficult to remove ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). This page matches a rust mark on clothing to a remover by fabric and care label, with each remover's limits and hazards. Dye picked up from another garment in the wash is a different problem, covered in [colour bleeding in laundry](/blog/stop-color-bleeding-in-laundry/index.md). ## Which rust remover each fabric can take Find your fabric's row. If a cell says yes, then that remover is an option for that fabric; each cell names its source. Wool, silk, spandex and dry-clean-only items follow their own rows, whatever their colour. ## What not to rely on: chlorine bleach or detergent alone Do not use chlorine bleach on rust: chlorine bleach will set these stains ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). Clorox, which makes bleach, explains why: bleach, or any product that contains sodium hypochlorite, is an oxidiser formulated at an alkaline pH, which provides the conditions to oxidise iron and make a rust stain even worse ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). A normal wash is not the fix either: laundry detergent or typical stain removers are not going to be very effective on rust ([Purex](https://www.purex.com/stain-lab/outdoor-stains/how-to-remove-rust-stains.html)). ## Commercial rust removers: test, apply, rinse Use a commercial rust remover on white and colourfast fabrics, after testing that the fabric does not change colour ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). Follow the remover's label instructions to use it safely, and wear heavy-duty rubber gloves ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). ### 1. Brush off loose rust Gently brush off any solid rust particles on the surface, and try not to rub the stain ([Purex](https://www.purex.com/stain-lab/outdoor-stains/how-to-remove-rust-stains.html)). ### 2. Read the care label Read the care label before any stain removal method, and do not use any product or procedure it prohibits ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). The decoder reads each symbol on the care label, including the bleach triangle and the dry-clean circle. ### 3. Test the remover on a hidden area Apply a drop of the rust remover to dampen a hidden area and wait a few minutes before rinsing with water; no colour change means the item is colourfast ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). ### 4. Apply it to the damp stain, then rinse Dampen the stained area with water first, then apply the rust remover; when the stain is no longer visible, rinse with clean water ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). If the mark remains, repeat the process, following the manufacturer's directions ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). ### 5. Wash, then air dry Machine wash as directed on the care label, and let the item air dry ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). ### Know what is in the bottle The sources name three kinds of rust remover ingredient: - **Hydrofluoric acid.** Texas A\&M AgriLife Extension advises against rust removers containing hydrofluoric acid because they are extremely toxic and can burn the skin ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). Rust-Oleum's data sheet for Whink Rust Stain Remover lists water, hydrofluoric acid and Bitrex, and the product is not a general purpose rust remover: it is for white sinks and toilets, colourfast fabric and carpets ([Rust-Oleum](https://www.rustoleum.com/-/media/DigitalEncyclopedia/Documents/RustoleumUSA/TDS/English/CBG/Whink/WNK_01_Whink_Rust_Stain_Remover_TDS.ashx)). - **Oxalic acid.** Rust removers based on oxalic acid may change the colour of some dyes; avoid contact with the skin ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). In its carpet and tile rust instructions, UGA Extension warns that oxalic acid is poisonous: do not let it touch the skin, and wear rubber gloves ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). - **Sulfite-salt powder.** Iron OUT Powder's safety data sheet lists sodium hydrosulfite, sodium metabisulfite, citric acid and sodium sulfite, with a pH of 5.5-6.5 ([Summit Brands](https://summitbrands.com/wp-content/uploads/2021/12/Iron-OUT-Powder-English-GHS-Rev-11-02-2021.pdf)). > Whink's data sheet warning reads "DANGER-POISON": avoid contact with skin, > eyes or clothing, do not breathe vapours, harmful or fatal if swallowed; in > case of contact, flush eyes and skin with plenty of water for at least 15 > minutes and get medical attention. Its clothing directions: wear heavy-duty > household rubber gloves, test for colourfastness, dampen the stain, apply a > few drops, and when the stain is gone rinse the area thoroughly with cold > water, then machine launder and dry before wearing; avoid contact with washer > and dryer surfaces > ([Rust-Oleum](https://www.rustoleum.com/-/media/DigitalEncyclopedia/Documents/RustoleumUSA/TDS/English/CBG/Whink/WNK_01_Whink_Rust_Stain_Remover_TDS.ashx)). ## Iron OUT in the washer: whites, or colourfast items one at a time For white laundry, the directions for Iron OUT powder are 1/2 cup (US measures: about 118 ml) added to warm water as the washer fills (in a front-loader, in the detergent drawer), a 5-minute soak with the clothes, then detergent and the rest of the wash and rinse ([Iron OUT](https://summitbrands.com/iron-out-rust-stain-removers/powder/)). On coloured laundry, Iron OUT says to test all colours first, use it only on colourfast dyes and wash each item separately; the product may irreparably damage colours and embroidered logos ([Iron OUT](https://summitbrands.com/iron-out-rust-stain-removers/powder/)). Its safety data sheet classifies the powder as causing serious eye damage (wear eye protection) and warns that contact with acids liberates toxic gas ([Summit Brands](https://summitbrands.com/wp-content/uploads/2021/12/Iron-OUT-Powder-English-GHS-Rev-11-02-2021.pdf)). **Recommended product** ## Lemon juice, salt and sun: where the sources disagree The method: sprinkle salt on the stain, squeeze lemon juice on it and spread the item in the sun to dry; rinse thoroughly and repeat if necessary ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). Texas A\&M says lemon juice and salt may be effective on rust ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). Clorox disagrees: it says vinegar and lemon juice are weak acids and typically are not strong enough to remove rust stains ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). Its limits: lemon juice and sunlight can both bleach colours, sunlight may turn some white fabrics yellow, and lemon juice may damage fabric texture or colour ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). ## Cream of tartar boil: boil-safe fabrics only If it is safe to boil the fabric (generally some cottons and linens), boil the stained item in 4 teaspoons of cream of tartar per 1 pint of water (US measures: about 20 ml in 473 ml) until the stain is removed, then rinse thoroughly ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). ## A whole white load with rusty discoloration For rusty discoloration across a load of white items, UGA's route is detergent plus one cup (US measure: about 237 ml) of oxygen bleach, soaking the clothes for 10-15 minutes, then laundering; a commercial colour remover may also be used ([UGA Extension](https://site.extension.uga.edu/textiles/care/stain-removal/remove-stains-from-iron-rust/)). Check each item's bleach triangle first: **bleach-any** **bleach-oxygen** **bleach-no** On the care label, a triangle with two oblique lines allows oxygen bleach but not chlorine bleach, an empty triangle allows chlorine and oxygen bleach, and a crossed-out triangle means no bleaching — use only bleach-free detergent ([GINETEX](https://www.ginetex.net/gb/labelling/care-symbols.asp)); the fibre-by-fibre chart is in [what fabrics can you bleach](/blog/what-fabrics-can-you-bleach/index.md). Colour removers will remove most dyes: use one when bleaches are not effective and you are willing to re-dye the item ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). ## Wool, silk, spandex and dry-clean-only items Chlorine bleach is not for wool, silk, spandex, polyurethane foam or blends of these fibres, for embossed or flame-retardant finishes, or for fabrics labelled no chlorine bleach ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). None of the sources on this page names washable wool, silk or spandex in its rust directions. When in doubt, leave it to a professional dry cleaner and point out the location and type of the stain ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). A rust remover is not for a "dry clean only" garment: take it to a dry cleaner and show them the stain ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). The home procedures in Texas A\&M's guide do not apply to fabrics labelled "dry clean" ([Texas A\&M AgriLife Extension](https://agrilifeextension.tamu.edu/wp-content/uploads/2025/04/Removing-Stains-From-Washable-Fabric.pdf)). ## If rust spots appear after every wash An older washing machine can have rust inside that transfers to laundry, especially if wet clothing is not removed right after the rinse cycle; examine the inside, especially the drain holes in the basket. Clorox says replacing the washer is necessary to eliminate this problem ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). The water can be the source too: water that looks clear can still contain iron oxide; a water test kit identifies metals, a softening system works for lower iron levels and filtration for higher concentrations ([Clorox](https://www.clorox.com/learn/removing-orange-rust-stains-from-clothes/)). ## Mistakes to avoid > **Warning:** > - **Drying before checking.** The heat could set the stain and make it impossible to remove (Purex). > - **Iron OUT with an oxygen or chlorine product.** Its laundry directions say not to use peroxide, bleach, bleach-detergents, oxi stain removers or oxi-detergents with it (Iron OUT). > - **Whink with another cleaner.** Its directions say not to use it with other household cleaners (Rust-Oleum). > - **A rust remover on a fabric that changed colour in the test.** Texas A&M limits commercial rust removers to white and colourfast fabrics (Texas A&M AgriLife Extension). ## Related reading - [Stain removal guides](/stain-removal/index.md) — the hub for every stain type. - [How to remove set-in stains](/blog/remove-set-in-stains/index.md) — stains that have already been through the dryer. - [What fabrics can you bleach?](/blog/what-fabrics-can-you-bleach/index.md) — the fibre-by-fibre chlorine and oxygen chart. - [Colour bleeding in laundry](/blog/stop-color-bleeding-in-laundry/index.md) — when the mark is dye from another garment.
