When aluminum is exposed to water, it creates a shield of aluminum oxide that stops it from rusting. This oxide layer on aluminum is strong and can resist corrosion, which is why it’s good for places with moisture. But if there are salts or other metals around, chemical reactions can happen and cause galvanic corrosion. Even though aluminum doesn’t soak up water, having water sit on it for too long can cause corrosion in certain spots if there are impurities on the surface. It’s important to clean and take care of aluminum regularly to keep it lasting a long time in wet areas.
