How to care for my copper flashlight？
Why use copper as a flashlight to make materials?
- Excellent Thermal Conductivity: Copper exhibits exceptional thermal conductivity, allowing heat generated within the flashlight to dissipate efficiently. This reduces the risk of overheating and enhances the safety performance of the flashlight.
- Corrosion Resistance: Copper possesses high corrosion resistance, making it less susceptible to oxidation or corrosion compared to other metals like iron or aluminum. This means that the flashlight has a longer lifespan, especially when used in humid or harsh environments.
- Aesthetic Appeal: Copper has a unique metallic luster and color, lending the flashlight a premium and elegant appearance. This aesthetic appeal may be a significant factor for certain users.
- High Ductility: Copper is easily malleable and can be formed into various shapes and designs with ease. Manufacturers can create flashlights in different forms to meet the needs and preferences of diverse users.
- Environmental Friendliness: Copper is a recyclable metal. Using copper for flashlight production can reduce resource consumption and contribute to lowering environmental impact.
Copper develops black spots due to oxidation, a chemical reaction with oxygen in the air and moisture. Over time, copper surfaces form copper oxide, resulting in the appearance of black patches. This process is accelerated in the presence of sulfur compounds, leading to the formation of black tarnish on copper surfaces.Despite the fact that it looks like something is wrong, the process of oxidation is a protective measure. The discoloration is actually a shell that forms over the copper's surface in order to protect it from breaking down or being destroyed by the elements.
How to remove the oxide layer on the copper?
- Solution 1: For signification corrosion on the copper, make a paste of equal parts vinegar, flour and salt. Rub it all over the affected area and allow it to sit for about 30 minutes.Then wipe it clean with soapy water and dry it well. Salt has metal cleaning properties all on its own as well. If you have stubborn copper oxidation due to exposure to air and water, cover the surface of the copper with salt and begin to rub it vigorously with a soft rag. Keep rubbing until the bluish-green discoloration has disappeared.
- Solution 2: It may surprise some people, but ketchup is actually an excellent copper polish. You only need to rub ketchup all over the affected area and leave it there for 20 minutes before buffing it clean with a soft, damp cloth. Once you've finished cleaning the oxidation from the exterior of the copper object, rinse it with warm water. After rinsing, be sure that you promptly and completely dry the object with a soft cloth. By keeping it dry, you remove the risk of new blue-green oxidation building up again right after you cleaned it.
- Solution 3: Once you've tried those methods, if it's still not working, you can cut a lemon in half and cover the surface with salt. Rub the salted lemon half all over the copper oxidation, using it as a scrub brush. Scrub until the surface is shiny or until you've removed as much oxidation as seems possible.If there is still oxidation after using the lemon and salt method, there are further steps you can take. Take the other half of the lemon and squeeze it into a jar or bowl. Add a few spoonfuls of cream of tartar and stir to make a paste. Apply the paste to the copper object, covering all affected areas. Leave the paste on the surface of the copper for at least one hour and up to two. Then, wipe the surface clean.
- Solution 4: If nothing removes all traces of oxidation, and there is still either blackish or bluish-green tinting on your copper, you can try to boil it away. Place the copper object in a pot of water that you have brought to a boil. Boil the object until the very last of the tarnished bits have fallen away. You may need to scrub it with salt after taking it out of the pot.
- Solution 5: While there are commercial cleaners that cleanse metals like copper, brass, silver and gold, they are not necessary unless you find that you are having no luck with the natural methods. Generally, commercial cleaners are merely a harsher chemical version of these natural methods. However, if you are unable to clean the copper objects with the natural methods, then they are a good option.
How to Care for Copper？
As one of the important outdoor tools, flashlights cannot avoid contact with oxygen and water. However, although oxidation is a protective layer, not evidence of damage, most people do prefer the luster and clean appearance of copper.
In order to correctly care about copper, it is important to understand it. Copper is a metal alloy and soft metal. This means that scrubbing with too harsh abrasive commercial cleaner will damage the surface of the copper, leaving scratches. If too much pressure is applied, copper is also easy to bend and warp.
In order to protect the copper from being oxidized and further damage, it is best to apply it with olive oil or flaxseed oil after cleaning. This oil can help create an obstacle, prevent oxidation for a period of time, and make your copper look shiny and new.
