Heather from a Southern California beach town contacted me recently about using sand for cleaning garden tools. She had come across my Seattle Times article on tool maintenance. This seemed like a good time to revisit this task, which I do every winter.
Someone from my local gardening group keeps her garden tools in a bucket of sand and swears by it. Then I posed the question if it has to be beach sand with salt and then refreshed once in a while and kept out of the rain or garden sand with no salt. She didn’t know either. And of course my google detective work isn’t panning out.
I look forward to your suggestions,
Cleaning garden tools in a bucket of sand is a great maintenance technique. I often just plunge them into the sand 4 or 5 times, then brush them off with a rag and store them in a rack or on a shelf. But you can keep them in the sand too.
I would not use sand that has salt in it – salt is corrosive to metals. Get a bag of play sand or construction sand (used to set patio pavers) from Home Depot or Lowe’s. Try to store the bucket of sand under cover, so it’s not too wet.
If you’re gardening near the beach in soil that has salty sand in it, I’d clean the tools promptly after gardening to get that salt off.
Some people mix a bit of oil into the sand (motor oil or vegetable oil) because oil on metal tools inhibits rust. But the oil is not strictly necessary.
If the tools already have rust or caked on stuff you can scrub that off with a wire brush or steel wool. A bit of oil while doing that helps too. You might want to wear gloves for that job.
Another great thing to do for your tools with wooden handles is to clean and smooth the wood with sandpaper once a year and rub in some linseed oil. That keeps the wood from cracking.
Final tip: sharpen digging tools like spades, shovels and trowels with a file (a “mill bastard” type, available at most hardware stores) in the winter. Then they’ll be all ready to use next season.
There, now you know more than you ever wanted to about garden tool maintenance.
