This step is optional but recommended if the blades on your garden tools are developing rust. If your tools have any removable parts, start by disassembling them before cleaning. In a container, create a mixture of one part water and one part vinegar, enough for the blade of your tools to sit in. Soak tools in the mixture overnight.
After letting your tools soak in the vinegar and water mixture overnight, remove tools. While they're still wet, use steel wool or a strip of sandpaper to brush off the rust on the blades. If you desire to clean your wood-handled tools, pour linseed oil on a cloth. Use the cloth to rub your wooden handles to make them look brand new.
Find a bucket big enough for your tool's blades to stand in. Fill the bucket with dry sand. Gradually add vegetable oil and mix well. The sand should be a similar consistency to packed snow—you should be able to make a ball of it with your hand.
Insert tools into sand mixture and let stand. Store in a cool, dry place (like a garage) during the winter.
