Proper maintenance of your snow shovel will depend on the type of material your handle is made of. While the blade is often waterproofed for extra durability, the handle often does not have protective coating. For a wooden model, wipe it down with linseed oil once a year and store the shovel in a safe, dry area. If you have a shovel with a metal handle, remember to wipe it down on a regular basis so moisture does not sit on the surface to avoid rusting. Fiberglass and plastic require the least amount of maintenance since they do not rust or absorb moisture. To ensure your snow shovel lasts longer, keep it in a dry place and reduce exposure to chemicals like the salt which is used to evaporate snow and ice on the roads.
