Winterization is the process of preparing a home, vehicle, or outdoor equipment for the cold winter months. This involves taking steps to protect against freezing temperatures, snow, and ice. Common tasks include insulating pipes, sealing windows and doors, and ensuring heating systems are functioning properly. For vehicles, winterization may include changing to winter tires, checking antifreeze levels, and ensuring the battery is in good condition. Outdoor equipment, such as lawnmowers and grills, should be cleaned and stored properly to prevent damage from harsh weather. These preparations help maintain functionality and extend the lifespan of various items.
