Clean garden tools by knocking off the soil after every use, scrubbing off what's stuck with a stiff brush and water, drying them, and wiping the metal with a little oil. Pruners also need the sap wiped off, plus a wipe of 70% rubbing alcohol after cutting diseased plants. Once a year, remove rust and sharpen.
The 30-second routine after every use#
Most rust starts with a spade that went back in the shed still caked in wet soil. The fix is a quick routine:
- Bang the tool against a post or scrape it with a stick so the loose soil falls back into the bed.
- Brush or hose off what's left. A stiff brush does most of it; you only need water for clay.
- Dry the blade and the joint where the metal meets the handle. That joint stays damp longest and rusts first.
- Hang it up or stand it head-up in a dry spot. Don't leave tools lying on the shed floor or standing in a bucket of water.
Some gardeners keep a bucket of builder's sand mixed with a little oil by the shed door and plunge spades and forks in a few times after use. It scours off the last of the soil and leaves a thin film of oil behind. It works, though a brush and an oily rag do the same job.
How to clean pruners, loppers and shears#
Cutting tools collect sap, which goes sticky, picks up dirt and makes the blades drag. After each session, wipe the blades with a rag. When sap has built up, rub it off with rubbing alcohol or a sap remover and a scouring pad, working the blades open and closed so you reach the pivot. Dry them, put a drop of light oil on the pivot and close the blades or lock them before you put them away.
If the pruners have been in diseased plants, clean off the visible gunk first, then disinfect. Disinfectant doesn't work well through a layer of sap and soil.
How to disinfect pruning tools#
Iowa State University Extension's advice on sanitizing pruners gives two practical options:
| Disinfectant |
How to use it |
Downside |
| 70% isopropyl (rubbing) alcohol or ethanol |
Wipe or dip the blades, straight from the bottle. No soak needed. |
Not recommended for fire blight on apple trees |
| Household bleach, 1 part to 9 parts water |
Soak the blades at least 10 minutes, then rinse with clean water |
Corrodes metal; mix fresh and use within 2 hours |
Alcohol is the easier choice for most people because it's less corrosive and doesn't need soaking. When you're cutting out disease, Iowa State says to disinfect between plants at minimum, and ideally between cuts. The Royal Horticultural Society's disease prevention guidance puts disinfecting pruning tools and cutting knives alongside cleaning pots and seed trays as basic garden hygiene.
Bleach left on steel starts rust quickly, so rinse, dry and oil the blades afterward.
How to remove rust from garden tools#
The RHS's October jobs list covers the basic method: clean off the mud, rub the rust off with a wire brush, then apply a little oil to the metal. In more detail:
- Wash and dry the tool.
- Scrub the rust with a wire brush or steel wool until you're back to bare metal. A wire wheel on a drill is faster for spades with a lot of surface rust.
- Wipe off the dust.
- Sharpen the edge if it needs it. Hoes and spades take a file; pruners need a fine sharpening stone along the existing bevel.
- Wipe a thin coat of oil over all the metal. Any light machine oil works.
Pitting that's deep enough to catch a fingernail won't brush out, but a pitted spade still digs fine once it's oiled. A cracked or bent blade needs replacing.
Wooden handles#
Wood handles dry out, crack and give you splinters. Once a year, sand rough spots smooth with medium sandpaper and rub in a wood oil, letting it soak in before you wipe off the excess. Check the handle while you're at it. A split running along the grain or a head that wobbles on the shaft is a repair or a replacement, not something more oil will hold together.
End-of-season checklist#
In fall, before the tools go away for winter:
- Clean, dry and oil every metal tool, including the ones you think you cleaned last time.
- Sharpen pruners, hoes and spades.
- Oil wooden handles.
- Drain hoses and bring them inside along with any sprayers, as part of getting the house ready for winter.
- Make a list of anything broken so it's fixed or replaced before spring.
This guide covers hand tools. Powered tools need the battery out or the spark plug lead disconnected before you clean near a blade, and the lawn mower maintenance checklist goes through that. Garden furniture has its own routine in the outdoor furniture guide. If the end-of-season clean tends to turn into an end-of-February job, a recurring reminder in ChoreLists.com for the first weekend of October takes care of that.
