Have you ever noticed a piece of brass jewellery or decor turning green over time? It’s not a sign that the item is old or worn out; instead, it’s a natural reaction when brass is exposed to air. In this blog post, we’ll explore why brass turns green and what you can do to prevent it.
Brass is an alloy made up mostly of copper and zinc. When exposed to air and moisture, the copper in brass reacts with oxygen to form copper oxide — also known as verdigris — which is the cause of the green colour on your brass items. Oxidation depends on how much humidity and oxygen are present in the surrounding environment. So if you live in an area with high humidity, your brass items are more likely to turn green faster than those kept in drier climates.
The good news is that there are steps you can take to protect your brass from oxidation. For example, you can use polishes or waxes designed to clean and protect brass surfaces. These products create a barrier between the metal surface and the elements, reducing the amount of oxidation that occurs when exposed to air and moisture. You should also keep your brass items away from acidic chemicals such as vinegar and lemon juice, which can further speed up the oxidation process.
Lastly, if your brass item does start turning green but you want to wait to clean it, there are simple solutions like covering it with clear nail polish or spray paint that help slow down the oxidation process until you’re ready to clean it off properly.
Conclusion:
Keeping your brass items looking their best requires some extra care and effort due to their tendency to oxidize when exposed to air and moisture. Fortunately, there are ways you can prevent this from happening by using products designed for cleaning and protecting metals as well as avoiding contact with acidic chemicals whenever possible. With these tips in mind, you can ensure your favourite pieces of brass stay shiny for years!
