Crean Mate Tool Cleaner is incredibly useful for cleaning up secateurs, shears and knives, removing rust and grime.
Crean Mate removes resin, rust, and other gunk from blades of secateurs, shears, and knives. Simply add a few drops of Camellia Oil to the blade (or water works fine, but you ought to oil later anyway) to the blade and use as you would a rubber eraser. Test before using on prize blades as this product has a roughish texture and might scratch polished surfaces. After scouring, wipe tool and and store in a dry place.
