Prep first
Before you start
- Move the rusty object off the wood and blot any wet residue with a dry cloth.
- Keep chlorine bleach away from rust. It sets the stain and makes it more intense.
- Work on the spot alone so the wood around it stays as dry as possible.
Rust on wood is iron that has soaked into the grain or settled under the finish, usually from hard household water or a metal object left sitting on the surface. Wood reacts badly to the wrong cleaner, and a worn or wet finish lets the mark sink in further. Whether it lifts depends on whether the rust is on the finish or in the wood itself, so look at it in good light before you start.
Start with a paste on bare wood, and keep acid rust remover for hard surfaces well away from it. On painted wood or a painted deck, test a hidden spot first so the paint doesn't lift. Iron stains on a wood table usually take a few gentle rounds, and a pro is worth calling if the mark survives them.

6 steps
Step by step
Step 1 of 6a few minutes
Test a hidden spot first
Dampen a hidden area of the wood, wait a few minutes, then rinse it. Check the spot for any color change before you treat the rust.
Careful. Wet mops and steam mops damage the finish on wood floors and, over time, the wood.
Step 3 of 6
Spread the paste and let it dry
Spread a thick layer over the rust so it covers the whole spot. Leave it in place until it dries completely, and don't scrape it early.
Step 4 of 6
Scrape off the dried paste
Once it's fully dry, scrape the paste off with a plastic scraper. Lift it in flakes rather than digging into the wood.
Step 5 of 6
Wipe the spot clean
Wipe the spot with a dry or slightly damp cloth to pick up any residue. Check the stain in good light to see how much has lifted.
Careful. Ammonia and household dust treatments aren't for wood floors.
Step 6 of 6
Repeat until the rust stops lifting
If rust still shows, spread a fresh layer of paste and go through the drying and scraping again. Stop once a round no longer lightens the stain, since more rounds won't help.

Best products for rust on wood furniture
If you'd rather buy a product, choose a rust treatment labeled for wood and follow its label directions. Pretest it on a hidden spot before using it on the stain.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on wood furniture, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
On bare wood, a rust mark should look lighter after each paste round, and the wood should look even once the paste is off and the spot is dry. If the dark mark stays the same after repeated rounds, it has probably reached the wood itself, and the paste won't lift it.
What changes for yours
Adjust for your wood furniture
Wood floors
On a floor, work on one board at a time and keep the rest of the boards dry. Spread the paste only over the rust, and wipe the spot with a dry or slightly damp cloth as soon as it's scraped.
If the stain is still dark after a few rounds, stop and check the finish before you try anything stronger.
Iron on wood
Iron stains from household water are the same iron oxide as rust, so the same paste works on them. Because the water keeps carrying the iron, the stain can come back after cleaning.
If the iron is still reaching the wood, the stain will return, so deal with that source before you treat the spot.
Painted wood and painted decks
Paint is a coating, so keep the paste to the rust itself and never let it spread onto the surrounding paint. Pretest a hidden area first so you can see how the paint reacts. Scrape gently so you don't chip the paint around the spot.
A deck or fence has more exposure to weather and more area to cover, so the decks and wood fences guide covers that case.
Iron on a wood table
Table rust usually comes from a metal object left on the top, such as a can, a pot or a tool. Move the metal object away first, or the rust keeps coming back.
Test the paste on a hidden area of the top, then keep it on the spot and wipe with a dry or slightly damp cloth. Let the wood dry fully before the table gets used again.
Wooden furniture
Furniture finishes vary, so check whether the piece has a wax, oil, shellac or surface finish before you treat the rust. Skip wood cabinet cleaners on waxed, oiled, shellacked or unfinished pieces, since they can damage them.
On a turned or carved piece, use the plastic scraper with a light hand so the detail doesn't get gouged.
Metal on wood
A metal object like a nail or a can leaves a rust mark by sitting in one spot on the wood. Remove the object first, or the stain keeps getting fed.
If the metal is still rusting, it can keep staining even after you clean the spot, so replace it or keep it dry before you treat the wood. Then follow the steps above and check the spot after each round.
Heavy or long-standing buildup
An old rust stain that has soaked into the grain usually needs more than one round, so plan on repeating the paste. Let the paste dry completely each time before you scrape it off.
If the stain has dried dark and hard, the paste may need a little longer to work, so give it the full time each round. Keep wiping to a dry or slightly damp cloth and don't push harder on the wood.
If it's still visible after several rounds, a home treatment has likely gone as far as it can, and a professional can look at the finish.
Vinegar, baking soda, peroxide and more
Do home remedies work on rust on wood furniture?
Most household remedies won't lift rust from wood, and some can damage the finish. A sodium citrate, glycerin and Whiting paste is the one option worth trying on wood.

What makes it worse
Mistakes to avoid
Don't use an acid rust remover on wood
Commercial acid rust removers can strip sealers and pit or strip wood, so they're off the list here. The paste gets the job done without that risk.
Don't wax over a surface finish
Wax can't go on top of a surface finish, so skip it when you polish after treating a stain. Check the finish first if you're not sure which one the piece has.
Don't scrape the paste while it's wet
The paste has to dry completely before it comes off, so wet paste just smears the rust around the grain. Wait for it to set, scrape it away, then go again if the mark is still there.
Don't add steam or extra water to loosen it
Steam and standing moisture can damage the finish and, over time, the wood beneath it. Keep the moisture to the paste itself and leave the mop in the cupboard.
Don't reach for ammonia on a wood floor
Ammonia and household dust treatments aren't approved for wood floors, so they add risk without helping the rust. Stick to the paste and a dry cloth when the stain is on a floor.
When to call a professional
Once the rust has worked past the finish, or the repair involves resanding, bring in a certified wood flooring professional or a furniture refinisher, depending on the piece. In homes built before 1978, disturbing more than 6 square feet needs lead-safe certification, so check the house's age before any sanding starts.
Questions
Will rust come out of wood completely?
Fresh rust on the surface often lifts fully with the steps above. Older stains that have soaked into the grain may lighten a lot without vanishing, and then a professional is the next step.
Can I use vinegar to remove rust from wood?
Usually not. White vinegar is typically too weak to lift rust, and wood can't take a soak. The paste in the steps is the better choice.
Why does rust keep coming back on wood?
Usually because iron is still reaching the wood. Iron in household water or a metal object still touching the wood keeps leaving rust, so remove that source first.
Will the paste lift the paint on a painted deck?
The paste isn't meant to lift paint, but paint can react to it. Keep the paste on the rust and check a hidden area first, and if the paint looks dull or lifted after the test, skip the paste on that surface.
Can I use this on a wood table with a finish?
Yes, after a pretest, since the finish decides how the wood reacts. If the test spot shows no color change, treat the rust and wipe with a dry or slightly damp cloth.
Can a dark rust mark on wood be lifted?
Sometimes, but it's usually a repair more than a cleaning job. If the mark has reached bare wood, the paste may lighten it over several rounds, and anything left after that may need a professional to sand the area.
Is steel wool safe to use on rust marks in wood?
Keep abrasives out of the first pass. Once the paste has done its work, very fine steel wool or a synthetic pad used lightly can buff a leftover mark, but coarse pads cut through the finish and leave their own scratches.
What should a hidden-spot test on wood show?
Dampen a small patch, wait a few minutes, rinse, and check for any color change. If the spot looks the same once dry, you can go ahead with the visible rust, and a change means the finish needs a different approach.
