Whether you can leave your aluminum outdoor furniture outside during the winter depends on several factors, but generally, it is possible with some precautions. Aluminum is a popular choice for outdoor furniture due to its inherent resistance to rust and corrosion. However, winter conditions still pose risks that can affect its appearance and longevity.
The primary advantage of aluminum is that it won't rust like iron or steel. This makes it more resilient to moisture from snow and rain. Despite this, prolonged exposure to harsh winter elements can lead to other issues. Moisture can become trapped in crevices, potentially leading to the growth of mildew or, in rare cases, causing the metal to oxidize and develop a chalky white film. Furthermore, freezing temperatures can make the furniture more brittle, and heavy snow or ice accumulation could potentially cause stress on the welds or frames over time. The cushions and fabric, however, are a different story; they should always be stored indoors to prevent mold, mildew, and fading.
If you decide to leave your aluminum furniture outside, proper preparation is key. Thoroughly clean the furniture with a mild soap and water to remove dirt and grime. Applying a protective car wax can create an additional barrier against moisture. For the best protection, covering the furniture with durable, breathable, waterproof covers is highly recommended. These covers allow moisture to escape while shielding the furniture from direct contact with snow and ice. Ensure the covers are securely fastened to prevent them from blowing away.
Alternatively, if you have the space, storing the furniture in a garage, shed, or basement is the safest option. This completely eliminates exposure to the elements and ensures your furniture remains in pristine condition for many seasons to come. Stackable chairs can save space during storage.
In conclusion, while high-quality aluminum furniture can often withstand winter left outside, taking the extra step to protect it with covers or, ideally, storing it indoors will significantly extend its lifespan and keep it looking its best.
