Cleaning Garden tools for winter

A good garden tool isn’t just for Christmas ….

A cliché, but true. Proper tool maintainance, from the humble trowel to the mighty cultivator, will extend their useful life considerably. Regular cleaning, oiling, sharpening and generally looking after them will also make your life a lot easier. Some tools may only need an annual service whilst others will benefit from being cleaned after each use.

I have to admit that I’m no angel all the time when it comes to this, and I’m sure there have been times when we’ve all left a pair of secateurs outside or put dirty spades and forks away in the shed. When was the last time you sharpened your shears properly and gave your Dutch hoe some TLC?

As it’s now that time of year when a lot of the garden has been put to bed and tools are away for the winter. The lawn mower has gone into hibernation in the shed or garage like a bear settling down for the winter and even the hedge cutter can find a roost and be hung up until it’s needed again.
But before all that happens, I need to be kind to my tools so that I can use them when I need to come spring!

First of all, anything with a blade I will give a good clean. I’ll use a strong detergent, water as hot as I can bear a scrubbing brush and one of those sponges with a scourer on one side. It’s so easy to let a build up of rubbish, gunk, sap etc accumulate, especially on secateurs and loppers; scrape off the worst of it using another blade (I use the knife on my trusty Multitool) and then give them a good scrub. Once they’re all clean and dried, sharpen them using a file or whetstone if you have one, they’re cheap to buy anyway and well worth getting one. You’ll get a much keener edge on the blade, which will make pruning later on much easier and you’ll also get a cleaner cut, which will reduce the chances of disease getting in! One I’ve sharpened the blade, checked it and put a plaster on my thumb where I found out it was VERY sharp, I put a drop of oil on the hinge and any other parts that move and I also then spray the blades with WD40.



Next on my list are the hand tools; the trowels, spades, rakes and hoes etc. These are usually the ones that take the hardest beating each year, and so also end up looking the worst of all.
A good scrape of the worst of the built up dirt followed by a wire brush to really give them a thorough clean and then the detergent and scourer again to finish them off. Once the metal parts have all dried I wipe them over with an oily rag or again a light spray with WD40

I have heard a tip from a friend who has a bucket of sharp sand in his shed, which has been mixed with motor oil, when he comes in with used tools, he plunges them in and out of the bucket, the sand helps to clean the tools and the oil preserves against rust. I haven’t tried this I admit, it sounds like a good idea, but knowing me, I’d stub my toe on the bucket or kick it over!

Although much rarer these days, some of my tools have wooden handles, these handle can dry out and potentially split, or become weak and break under strain. A clean, light sanding and then a liberal dose of teak oil keeps the wood in good condition and also helps to keep it more flexible too.

I know a lot of people recommend and use linseed oil on their gardening tools, to preserve blades, prevent rust and on wooden handles etc. I am perhaps overly cautious though and don’t really want to have anything that could potentially burst into flames if I forget to do something like clear up properly. I’ll stick with WD40 and teak oil, thank you very much!

I’m not a mechanic by any means but I do carry out a few simpler tasks on any garden machinery I own. For major things I always use a professional as it’s just not worth doing a “bodge” job on any piece of machinery that could go wrong and be expensive to replace!

Cleaning is probably the most important part, especially on your lawn mower, the build up inside the deck of old grass, mud, leaves and goodness knows what else can lead to rust holes on a metal deck, or an inefficient grass collection, the blades catching in internal debris can be harmful too.



If you have a petrol mower, tip it back in the direction recommended by the manufacturer, if you don’t then trust me, the oil can go everywhere, and this can REALLY mess things up later on. I usually use an old paint scraper to get rid of the worst, then it’s back to brushes and hot soapy water to give it a thorough scrub. Whilst you’re waiting for it to dry off, take the blade off if you can (wearing gloves of course) and test the cutting edges. Sharpen using a file, balance it and put it back. If in doubt, take it somewhere that can sharpen mower blades and balance them properly. If a rotary mower blade isn’t balanced then the vibrations it will cause when in use will seriously harm the machine, not to mention it being absolutely awful to use too!

Check the oil regularly of course, and clean out air filters, or replace them, this goes for all petrol machinery throughout the year. It’s a similar routine for tillers and any other large, driven machinery. As a matter of course, before I start any machine, I always check the spark plug lead is intact and that it’s firmly seated onto the plug itself, this is from past experience and prevents some head scratching as to why the machine won’t start!

The internal workings of some of my electrical equipment I honestly leave well alone. I’m nowhere near qualified to take my hedge trimmer apart, so I don’t. I really good clean and brush down, Good old WD40 on all the moving parts and check all the wires and plugs for damage is about all I can do.
Obviously make sure your storage area is clean and dry too, no point cleaning everything up & putting it away only to find the more rust has accumulated over the winter!

These are definitely “chores” every year, but I’ve found that it’s well worth it, keep your favourite tools clean and tidy and you’ll have as much pride in them as you will your garden!

Obviously more hints and tips are more than welcome from everyone!

I’ve been gardening for as long as I can remember, my first earliest memory being planting seeds in my Grandfather’s prestige flower bed and having a prize lettuce growing there, which he proudly left to show everyone.
Since then, gaining knowledge and experience from both my Grandfather and my Father, I’ve continued to garden, both as a hobby and later on as a professional gardener and landscaper for 12 years. I love all aspects of it, from the design and build, to the planting out of summer borders with plants you’ve either grown from seed or raised from plugs. Unusual varieties always catch my eye and I’m keen to try growing them, even if sometimes it means learning from my mistakes.
