To remove stubborn mulch, soak and scrub tool with a stiff brush. Rub off rust with very fine sandpaper or with fine steel wool dipped into kerosene. Dry tools with an absorbent rag or paper towels, as dampness can lead to rust. Sharpen cutting edges with a file or a whetstone, filing from the outer edge to the center. Wipe metal surfaces with an oiled cloth or store metal tool ends in a bucket filled with coarse sand soaked in motor oil. Keep wooden handles from drying out by applying a light coat of boiled linseed oil and buff. Tighten screws and dab a drop or two of light machine oil on moving parts. Store tools out of reach of children in a cool, dry spot. Winter is an excellent time to make an organized pegboard or other storage system for your tools.
