The question of whether to leave metal outdoor furniture outside all winter is common, and the answer isn't always straightforward. While many quality metal furniture pieces, such as those made from aluminum or powder-coated steel, are designed to withstand the elements, prolonged exposure to harsh winter conditions can still take a toll.
Leaving your furniture outside can lead to several issues. Moisture from snow and rain is the primary enemy, as it can lead to rust on steel and iron frames, even with protective coatings. Constant freezing and thawing cycles can cause coatings to crack or peel over time. Furthermore, dirt, leaves, and debris can accumulate, leading to stains and providing a damp environment that accelerates corrosion.
If you decide to leave your metal furniture outside, taking proactive steps is crucial. The most important measure is using high-quality, breathable waterproof covers designed for outdoor furniture. These covers protect from direct precipitation and UV rays while allowing moisture to escape, preventing mold and mildew. Before covering, ensure the furniture is thoroughly cleaned and completely dry. Elevating furniture pieces off wet ground, such as by placing them on a patio slab or using pot feet, can also prevent water from pooling and causing damage to the legs.
However, for the longest lifespan and to maintain its pristine appearance, storing metal furniture is the best option. If you have space in a garage, shed, or basement, this is ideal. Before storing, clean the furniture with a mild soap solution to remove all dirt and grime. Rinse thoroughly and allow it to dry completely to prevent trapping moisture. For added protection during storage, you can apply a protective wax or a fresh coat of sealant if the manufacturer recommends it.
In conclusion, you can leave sturdy metal furniture outside if you properly protect it with breathable covers and prepare it correctly. But if you want to guarantee its beauty and structural integrity for years to come, finding indoor storage for the winter months is the most reliable strategy. Assess the quality of your furniture, the severity of your local winter, and your storage options to make the best decision.
