Prep first
Before you start
- Keep chlorine bleach away from rust. It sets the stain and makes it more intense.
- Remove the rusty object and blot any wet residue.
- Pretest any rust remover on a hidden area first.
Rust on a tool is iron oxide, and it can look like a lost cause, but most of it lifts with patience. Loose surface rust usually comes off with steel wool or a wire brush. Deeper rust on bare steel needs an overnight soak in white vinegar before it lets go, and fresh rust comes off more easily than rust that has sat for years.
Check the finish first, since chrome, aluminum and painted tools each need different treatment. For a rusty shovel or old garden tools, a rust remover made for hard surfaces does most of the work. Plan on a second round for the worst spots, and stop once the bare metal looks clean.

5 steps
Step by step
Step 1 of 5
Scrub off the surface rust
Work 000 or 0000 steel wool or a wire brush over the rusty areas until the loose, flaky layer is gone. Cover the whole rusty area evenly so you can see how much rust is left for the soak.
Tip. Start with the steel wool, then switch to the wire brush for stubborn spots.
Step 2 of 5
Soak heavy rust in vinegar
If the rust is still heavy after scrubbing, soak the tool in white vinegar overnight. Only bare steel tools go in vinegar this way, since the soak isn't meant for painted, coated or chrome finishes.
Step 3 of 5
Wipe the tool down
Take the tool out of the vinegar and rub it with a damp rag to lift off the loosened rust. Wipe the whole tool, including the joints and any hard-to-reach spots.
Step 4 of 5
Dry and scrub what remains
Dry the tool completely before going further. Then remove the rust that's left with the wire brush or steel wool.
Step 5 of 5
Coat the metal to slow rust
Once the tool is dry, spray or lightly coat it with vegetable spray or another plant-based oil. A light coat is what helps prevent new rust from forming.
Careful. On garden tools, avoid petroleum-based oils; they can harm the soil.

Best products for rust on tools
Choose a commercial rust remover labeled for the metal your tool is made of. Read the label before you start.
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on tools, 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
The scrubbing is working when the orange layer comes off and the metal underneath starts to look bare and clean. If a spot still looks rough after one pass, that's your cue for the vinegar soak on bare steel, not more force.
What changes for yours
Adjust for your tools
Chrome-plated tools
Chrome plating scratches easily, so the steel wool and abrasive pads from the main steps stay off these parts. Don't apply cleaners to hot chrome, so let the tool cool first.
For set-in rust on chrome, stick to a cleaner the maker approves and follow its label. Wipe off any residue with a damp rag once the treatment is done.
Aluminum tool parts
Aluminum parts need gentler handling than bare steel. Skip the vinegar soak here, since it's for bare steel tools only.
Anodized aluminum can't take steel wool or abrasive cleaners, and strong alkaline or caustic detergents can cause discoloration. Wipe with a damp rag and dry the part fully before coating it.
Garden tools and shovels
Garden tools and shovels use the same steps, starting with the steel wool or wire brush on the blade. Give the blade the vinegar soak only if the rust is heavy and the blade is bare steel.
Keep any wooden handle out of the vinegar, since acid removers can damage wood. Dry the blade and handle fully, then coat only the metal part.
Tools with painted or coated finishes
Acids can strip sealers and damage painted or coated finishes, so skip the vinegar soak on these tools. Use the wire brush or steel wool only on the rust showing, and keep the pressure light so the finish stays put.
Work on the rusty spots only and leave the sound paint alone. Once the spot is dry, a light coat of vegetable spray or plant-based oil on the bare metal helps prevent new rust.
Cast-iron tools
A small rust patch on cast iron can be scrubbed off with a cloth and some salt, which is the gentlest place to start. Wipe away the loosened rust afterward and dry the spot right away.
Salt is a light scrub, so for heavier rust move on to the main steps. For the full cleaning routine on cast iron, see our cast-iron guide.
Heavy or long-standing buildup
Old rust is harder to shift because it has had time to bond with the metal. Rust stains may be very difficult to remove, so plan on more than one pass. Expect the first round to lift the loose top layer and leave the deeper rust behind.
If the rust has dried hard, give the tool the same vinegar soak again, then scrub it with coarse steel wool or lump pumice. Both work on bare steel tools after the soak. Repeat the soak and scrub if rust is still showing after the first round.
If rust still shows after a second round, expect a lighter result rather than fully restored metal. Coat the tool once it's dry so the cleaned area stays protected.

Do home remedies work on rust on tools?
Most household remedies don't remove rust, so only a few are worth trying on tools. It shows which ones belong in these steps and which to leave alone.

What makes it worse
Mistakes to avoid
Don't leave tools wet or in vinegar
Take the tool out of the soak as soon as the time is up, then dry it fully. Leftover moisture causes rust, and a wet garden tool will rust in storage too.
Don't mix bleach with rust removers or vinegar
Bleach combined with rust removers, vinegar or other acids can release toxic gas. Rinse thoroughly between any two products, and never mix them in the same container.
Don't handle oxalic or hydrofluoric removers bare-handed
Oxalic acid is poisonous, and hydrofluoric acid is extremely corrosive to skin, so wear rubber gloves for either. Keep oxalic acid away from children and store the container out of reach.
Don't use bleach on aluminum, silver or steel that isn't stainless
Bleach can damage non-stainless steel, aluminum and silver, so keep it off those tool parts. Check what metal your tool is made of before you start, and follow the steps for bare steel only where it applies.
When to call a professional
Most rust on tools can be cleaned at home with the steps above. If a tool is part of a machine or has a finish you're unsure about, ask a repair shop before you start.
Questions
Can I use a wire brush instead of steel wool?
Yes. A wire brush does the same scrubbing job as steel wool in the first step, and it's handy for stubborn spots.
Can I use a commercial rust remover instead?
Yes, as long as its label covers the metal your tool is made of. Follow the label exactly and rinse thoroughly afterward.
What's the best way to remove rust from an old shovel?
Scrub the blade with steel wool or a wire brush first, then give it the overnight vinegar soak if the rust is heavy. Keep any wooden handle out of the vinegar, then dry, rub and coat the metal with a plant-based oil.
Will rust come off old tools completely?
Not always. Rust on old tools can be very hard to remove, so expect a lighter result after a second round rather than fully restored metal. Coat the metal once it's dry so the cleaned area stays protected.
Can I use salt on rust?
Only on a small rust patch on cast iron, where scrubbing with a cloth and salt can lift it. Keep salt off stainless steel, since it's unsafe there.
Does the vinegar soak hurt the tool?
On bare steel, the overnight soak is the method for heavy rust. It stays off painted, coated and chrome tools, and plain white vinegar is the one to use.
