How to Remove Rust From Garden Tools and Keep It Away

The Short Answer

To remove rust from garden tools, wash off the soil, dry the tool, and scrub the rust with steel wool, a wire brush or sandpaper. For rust that scrubbing does not shift, soak the tool overnight in a 1 to 1 mixture of vinegar and water first, as University of Vermont Extension advises, then scrub. Finish by wiping every metal surface with a thin coat of oil. The rust stays away if the tool is put back clean, dry and oiled, and stored off the ground.

Oregon State University Extension sums up the cause in one line: tools deteriorate from time and dampness combined with soil. Every step below removes soil or moisture, or puts a barrier between steel and air.

Match the Method to the Rust

Extension sources agree on abrasives as the main method and differ only in which one they reach for. The choice depends on the tool and how far the rust has gone.

Situation	Method	Source
Rust on shovels, hoes, saws, pruning shears	Coarse-grade steel wool or lump pumice	Wisconsin
Rust left after cleaning a digging tool	Wire brush, sandpaper, or both	Oregon State
Rust on pruner blades	Wire brush, sandpaper or steel wool	Illinois
Badly rusted pruners	Penetrating oil for 10 minutes, wipe, then steel wool	New Hampshire
Rusty hand tools and pruners	Vinegar and water, 1 to 1, overnight, then steel wool	Vermont
Rusted pivot bolt	Penetrating liquid before loosening	Oregon State

Wisconsin and New Hampshire both name coarse steel wool for rust. Oregon State and Illinois keep fine steel wool for the lighter job of taking off sap.

Remove the Rust, Step by Step

1. Clean off the soil. University of Wisconsin Extension suggests rinsing under running water or soaking in water, then removing what remains with a cloth, bristle brush or wire brush. For pruners, University of New Hampshire Extension uses warm, soapy water and a scrubbing sponge.
2. Take off the sap. Wisconsin uses soapy water or turpentine. University of Illinois Extension lists turpentine, alcohol, mineral spirits or fine steel wool for stubborn sap. Oregon State adds that a heavy buildup can be scraped with a paint scraper, taking care not to gouge the metal.
3. Dry the tool. New Hampshire wipes pruners dry before starting on the rust.
4. Scrub. Work the rusted areas with the abrasive from the table. On pruners, Illinois says to scrub away dirt, rust and sap from the blades with a wire brush, sandpaper or steel wool.
5. Soak if scrubbing stalls. For badly rusted pruners, New Hampshire applies a penetrating oil spray, lets it soak for 10 minutes, wipes the oil off with a clean cloth, and goes back to the steel wool. University of Vermont Extension’s soak is a 1 to 1 mixture of vinegar and water, left overnight. Afterward, scrub in a circular motion with steel wool, rinse in soapy water and then plain water, and let the tool dry thoroughly.
6. Oil the metal. When the tool is clean, rust-free and dry, coat all metal surfaces. A lightly oiled rag is enough.

Wear gloves and safety glasses for the scrubbing, as Illinois advises for any work on tool edges.

Choosing the Oil

The sources name different products, and the common point is a thin protective film on dry steel.

Wisconsin recommends oil, a penetrating spray lubricant, silicone spray or another rust inhibitor on all metal surfaces. Oregon State suggests a protective coating of spray lubricant or clean lightweight motor oil before winter storage. University of Vermont Extension rubs dried tools lightly with linseed or mineral oil and calls regular treatment with either one the best way to keep tools from getting rusty.

For pruners, New Hampshire oils the tool to lubricate the moving parts as well as to prevent rust, then wipes off the excess with a clean rag. Oregon State uses light machine oil on the pivot bolt and the base of both blades when reassembling a cutting tool.

For tools going away for months, Illinois offers one more layer: oil the metal and wood surfaces, and for additional protection apply a high-quality spray paint to metal surfaces. That suits the backs of shovels and the heads of rakes, not cutting edges.

Sharpen While the Steel Is Clean

A freshly cleaned blade shows its bevel clearly, so this is the moment to restore the edge. The short version is below, and how to sharpen pruners and loppers has the detail.

• Pruners. New Hampshire uses a diamond file set at the same angle as the factory bevel, drawn along the cutting edge with medium pressure in one direction, starting at the inside of the blade and working outward. A pass with a fine file over the back of the blade removes burrs.
• Shovels and hoes. Wisconsin recommends a 30° angle as typical. UF/IFAS goes steeper for shovels, about 45 degrees, and warns that a sharper edge dulls too quickly. Hold the file with both hands and push away from your body in long, steady strokes.
• Grass shears and other grass-cutting tools. Wisconsin gives a 20° to 22° angle.

Illinois warns against power grinders, because the heat from friction can make the metal brittle. Oil the edge again when you finish, since filing exposes bare steel. Sharp, clean pruners matter most at pruning time, and the late-winter pruning guide covers what to cut and when.

Habits That Keep Rust From Returning

Clean after each use. Wisconsin’s first instruction is to clean tools every time they are used, and Illinois states the storage condition plainly: tools must be clean and dry before they are put away.

Oregon State’s sand bucket makes the routine quick for long-handled tools. Keep a 5-gallon bucket 4/5 full of sand, optionally with about a quart of oil mixed thoroughly into it. After each day’s use, plunge the shovel, hoe or fork into the bucket a few times to clean the blade and coat it, then wipe it with a lightly oiled rag. Oregon State’s version uses car engine oil, and the oil is optional: the sand alone still cleans the blade, and the oiled rag supplies the coating.

Store tools off the ground and away from the weather. Illinois notes that tools left outside absorb moisture from wet grass and dew, and recommends a hanging rack for long-handled tools and a pegboard for short ones. Oregon State adds that wooden parts should not rest in contact with soil or concrete. The end-of-season version of this routine is in the fall checklist for cleaning and storing tools.

If you disinfect pruners between plants, Wisconsin’s method is at least 30 seconds in 10% bleach or, preferably, 70% alcohol. Dry and oil the blades afterward as you would after any wetting.

Look After the Handles

Handles fail from drying and cracking, and they need attention at the same sitting. Wisconsin suggests smoothing rough wood with medium-grit sandpaper, then using boiled linseed oil to keep handles from drying out, cracking and splintering. Illinois adds the finishing step: let the oil dry, then polish with a soft cloth. The guide to caring for wooden tool handles goes through the job in full.
