Copper is a popular metal for water bottles and other products because it is known for its antimicrobial properties. However, copper can also tarnish over time, especially if it is exposed to air and water. If you have a copper water bottle that is starting to show signs of tarnish, there are a few simple ways to clean it and restore its shine.
In this article, we will show you 3 simple ways to remove tarnish from copper bottles. These methods are safe and effective, and they will help you get your copper water bottle looking like new again.
What Causes Tarnish?
Tarnish is caused by oxidation, a chemical reaction that happens when copper comes into contact with water, air, or other corrosive elements. Oxidation causes the surface of the copper to become coated with a dark, greenish-black substance known as copper oxide. Copper oxide is what makes the surface of the copper tarnished and dull.
It is important to recognize the signs of tarnish and to take action to remove it if you want to keep your copper water bottle looking like new. To restore the original shine of your copper bottle, try one of the three methods outlined in this article.
How to Remove Tarnish
Now that you know what causes tarnish, here are three simple ways to remove tarnish from your copper bottle:
- Lemon Juice, Salt and Flour – Squeeze a lemon and mix the juice with a tablespoon of salt and a tablespoon of all-purpose flour. Spread the paste over the tarnished areas and allow it to sit for an hour. Using a soft cloth, rub the paste gently over the copper in small circular motions. Rinse with warm water and wipe dry with a soft cloth.
- Baking Soda – Combine two parts baking soda with one part water and stir to form a paste. Apply the paste to the tarnished areas and leave for an hour. Take a soft cloth and rub the paste gently in small circular motions. Rinse with warm water and dry with a soft cloth afterwards.
- White Vinegar and Salt – Combine equal parts white vinegar and salt and mix together. Immerse your copper bottle in the solution and allow it to sit for 30-45 minutes. Take a soft cloth and rub the tarnish gently in small circular motions. Rinse with warm water and dry with a soft cloth.
Things to Avoid When Cleaning Copper
When cleaning copper, there are a few things you want to avoid doing.
- Harsh chemical cleaners – Using harsh chemical cleaners such as bleach can damage the surface of copper. Avoid using them and instead stick with the natural ingredients we mentioned earlier.
- Scrubbing – Copper is a very soft metal, so scrubbing too vigorously can cause scratches that only add to the tarnish.
- Steel Wool – Steel wool is too abrasive for copper and can cause scratches that are hard to remove.
- Heat – Using high heat to clean copper can cause it to warp, so it’s best to stay away from the oven or any other source of high heat when trying to clean copper.
Conclusion
In conclusion, with the right techniques, you can easily clean your copper bottles and make them look shiny and brand new. Using natural ingredients like lemon and salt or baking soda and vinegar is the safest and most effective way to clean tarnish off of copper bottles. There are also some commercial cleaners available, but be sure to follow the instructions carefully to avoid any damage to the metal.
Remember to avoid using any harsh chemical cleaners or scrubbing too vigorously to avoid scratching the surface. Finally, do not use high heat to clean your copper bottles as that can cause warping. With these tips in mind, you will have no difficulty cleaning and maintaining your copper bottles.
