What are the effects of long-term exposure to hard water on aluminum outdoor chairs?

Long-term exposure to hard water can significantly impact aluminum outdoor chairs, leading to visible and structural damage over time. Hard water contains high levels of minerals like calcium and magnesium, which can leave stubborn white deposits or scale on the chair's surface. These deposits not only dull the appearance but can also trap moisture, accelerating corrosion and weakening the aluminum.

Additionally, the alkaline nature of hard water may react with the protective oxide layer on aluminum, causing pitting or etching. To mitigate these effects, regular cleaning with mild acidic solutions (like vinegar) and applying protective coatings can help maintain the chairs' durability and aesthetic appeal. Proper care ensures your aluminum outdoor furniture remains functional and attractive for years.
