A soft-bristled toothbrush or a gentle cleaning pad.How to Remove Oxidation From Cast AluminumĬast aluminum (casting refers to the process whereby molten aluminum is poured into a mold and allowed to solidify) can be found in several types of cookware. Read on for our step-by-step instructions on how to clean oxidation from cast, brushed, hammered and tarnished aluminum and why Schaumburg Specialties is the go-to expert for all your aluminum food production equipment needs. You only see a slight dulling of the surface, and this we can easily clean by using an aluminum brightener! Job done! On the whole, you don’t see this type of corrosion on a single part such as a pan rack that has surfaces that don’t touch. The only real way to deal with corrosion of this type is mechanically grinding or sanding to remove the contaminated outer surface. We tried to remove this by using an acid-type aluminum brightener which is a strong chemical and the results were minimal. For example, we recently had some tubing come in from a vendor that was seriously corroded. This difference with water stain corrosion is that it’s incredibly difficult to remove. This corrosion – sometimes referred to as water stain, which appears as a white, chalky substance – happens very quickly and can significantly affect the surface appearance of the metal. In our experience, aluminum corrosion is typically the result of aluminum raw materials being stored outside or having gotten wet between pieces stacked or bundled together. Amazingly, this initial oxidation actually helps to protect the aluminum from additional corrosion and is a big part of the reason why aluminum metal is so corrosion resistant! When aluminum oxidises, a white powdery and chalky coating develops on the metal’s surface. This is what happens when aluminum oxidizes. Corrosion refers to the process of metals wearing away due to a chemical reaction. Rust is a type of corrosion that occurs mainly in iron and steel, particularly when these materials come into contact with moisture. Here, it’s important to distinguish between rust and corrosion. It’s a natural process that results from the wear and tear of the metal over time (read more about the durability of aluminum).
