Garden tools take more abuse than anything else in the shed. They're stuck in wet soil, coated in sap, and often left outside overnight. The good news: a shovel, hoe or pair of pruners that's orange with rust is usually still worth saving. Rust on a garden tool is mostly cosmetic until it starts pitting the edge or the pivot. Here's the order I use, gentlest first.

1. Clean before you de-rust

• Knock off soil with a stiff brush and water, then let the tool dry. Rust removers and abrasives work poorly through caked dirt.
• Dissolve sap and resin on pruners, loppers and saws with a solvent such as mineral spirits or rubbing alcohol on a rag. Sap left on the blade traps moisture and makes the tool stick.
• Take pruners apart if they're designed for it (most quality bypass pruners are). Rust hides at the pivot and under the spring. Keep the parts in order on a rag and photograph them first.

2. Remove the rust

Match the method to how bad it is:

Whatever you use, dry the steel right away and oil it. Freshly cleaned steel flash-rusts within hours, especially in humid weather. For more detail on soaks and electrolysis, see How to Remove Rust from Tools.

3. Sharpen the working edge

• Shovels, spades and hoes: clamp the tool and file the existing bevel, usually on the top/inside face only, pushing the file away from the edge. You want a working edge, not a razor; a very thin edge chips on rocks.
• Bypass pruners and loppers: sharpen only the beveled cutting blade, following its original angle, with a diamond file or carbide sharpener. Leave the flat back face flat; just remove any burr with a light pass.
• Mower blades: remove the spark plug wire first, and check balance after sharpening. An unbalanced blade vibrates and wears the engine.

4. Refinish wooden handles

Gray, splintery handles cause blisters and eventually crack. Sand off the old varnish and the rough gray layer with 80 to 120 grit, wipe off the dust, then rub in boiled linseed oil. Let it soak in, wipe off all the excess, and let it cure before use. Repeat once a year. Replace any handle that's cracked through; a split handle can fail under load.

5. Protect and store

• Wipe metal with a light coat of oil or a long-lasting rust inhibitor before storing, and after each use in wet soil.
• Store tools hanging, dry and off the floor, not leaning in a damp corner or left out in the bed.
• Many gardeners keep a bucket of sand with a little clean oil mixed in and push shovels into it after use. Skip used motor oil; it's messy and contaminates soil.
• Clean pruners with rubbing alcohol between plants if you're cutting diseased growth.
