Few things make a woodworker’s heart sink faster than spotting a patch of rust on a favourite hand plane. Rust doesn’t just spoil the look - it can affect the performance of your tools, dull the blade, and pit the sole if left unchecked.
The good news? Preventing rust is simple once you understand what causes it and how to keep it under control.
In this article, we’ll look at why rust forms, how to prevent it, and the best habits to keep your planes in top condition.
Why Rust Happens
Rust forms when the iron in steel reacts with moisture and oxygen in the air. Even well-made planes - like those from Melbourne Tool Company, which use quality castings and precision-ground soles — will eventually rust if they’re neglected in the wrong conditions.
Common culprits include:
- High humidity in the workshop
- Condensation from temperature changes
- Sweat or fingerprints left on metal surfaces
- Storage near damp timber or concrete floors
Step 1: Keep It Clean
After each use, wipe down your plane with a clean rag. A few seconds of attention prevents a lot of trouble later. Pay special attention to:
- The sole and sides of the body
- The blade, and blade bed
- The adjuster and mouth area, where shavings and dust can trap moisture
Step 2: Add a Protective Layer
A thin layer of protection on the metal surfaces helps seal out moisture. There are several good options:
Camellia oil – A traditional favourite for woodworking tools. Light, non-sticky, and safe for wood.
Paste wax – Apply a small amount to the sole and sides, let it haze, then buff it off. This not only prevents rust but also reduces friction in use.
Corrosion inhibitors – There are dedicated products to inhibit corrosion that might be a good choice if you are storing your planes long-term, or shipping them overseas. Just be mindful of anything with silicone as an ingredient, as it may get onto your timber and react with any finishes.
Reapply every few weeks, or more often if your workshop is humid.
Step 3: Control the Environment
If your tools live in a shed or garage, you’re battling humidity. Here are some simple ways to win:
-
Keep your plane in the packaging it came in – each MTC tool comes in a purpose made foam-lined box, which is the perfect place to store your plane.
- Store above ground level – Keep planes off concrete floors and away from damp walls.
- Use a cabinet or toolbox – If you prefer to store your planes all together, closed storage slows air exchange and moisture exposure. Making the box out of a timber such as Camphor Laurel, that releases oils into the air, can further help prevent rust.
- Add desiccant packs or a dehumidifier – Small silica gel packs or powered dehumidifiers make a huge difference.
- Avoid direct drafts – Airflow from open doors or windows can bring in moist air.
Step 4: Maintain During Use
Every so often, check under the lever cap and blade for trapped dust and shavings — they can hold moisture against the metal.
Before planing resinous or green timber, apply a little wax to the sole. It prevents resin from sticking and provides a barrier against moisture.
If you notice early surface rust, remove it gently with fine steel wool (0000 grade), very fine Scotch-Brite pad, or a non-abrasive rust eraser. Heavier rust might require a rust remover gel – follow the manufacturer’s instructions, and use appropriate PPE. Don’t forget to reapply your wax or oil coating.
The Payoff
Rust prevention is all about small, consistent habits. A quick wipe, a little wax, and mindful storage go a long way.
Your planes will stay clean, bright, and ready to use — so when inspiration strikes, you can start making shavings instead of scrubbing corrosion.
At Melbourne Tool Company, we believe that good tools deserve good care. Whether you’re maintaining a single block plane or a full set of low-angle bench planes, a few simple steps will keep them performing beautifully for generations.
