If you want to sell your copper wire at a scrap yard or are preparing copper wire for soldering, you may want to clean it. While there are commercial cleaners that exist on the market, there are also a variety of ways you can clean copper with commonly found, all-natural ingredients. By stripping the wire of its plastic casing and using specific methods and solutions like vinegar and salt, you can easily break up the dirt and grime on your wire and bring it back to its original luster.
Steps
Place the wire on a flat working surface. Place the copper wire onto a flat surface that won't be damaged by a knife, like a cutting board. You'll be cutting into plastic, and the knife will likely cut into whatever surface you're working on.[1]
Make a slit into the plastic casing around the wire. Use a fine cutting tool like a razor blade to make a slit in the plastic casing that's around the wire. You can also use a wire stripper or pliers with a blade. Make a slit that goes completely around the casing of the wire.[2]- Use thick gloves to avoid cutting yourself when cutting the copper wire.[3]
- Be careful not to cut all the way through the copper wire when you cut the casing.
Advertisement- Separate the plastic from the copper wire. Slide the casing that's been cut and remove it from the copper wire. You should be able to separate the plastic portion from the wire by pulling on it. If there are portions of the plastic that aren't coming lose, go over them with a razor blade again.[4]
Fill a large pot up with water. Use a deep pot that's large enough to accommodate all your pieces of copper wire. Set the pot on the stovetop and set the heat to high.[5]- If you don't have a large pot you can boil your wires in batches.
Boil the copper wire in water for 10 minutes. Bring the water to a rolling boil. Carefully place your wires into the pot with the plastic casing still attached. The heat will warm up the plastic on the wire and make it easier to remove.[6]- Never burn your copper wire casing. It hurts the environment and reduces the value of your wire.
- Use thick gloves when handling hot metal.
- Remove the wire from the water using tongs. Turn off the stove and remove the copper wire from the water using the tongs. Place the wire on a rag or paper towels, but don't let them cool down too much.
- Pull the plastic casing away from the wire. It's important that you don't allow the plastic to cool or else it won't be soft enough to pull apart. Simply grab onto on end of the soft plastic and pull it away from the copper wire. If it's hot enough, it should slide off.
- Add 1 tablespoon (17.06 g) salt and 1 cup (236.58 ml) vinegar to a bowl. Salt and vinegar can help clean off any tarnish or corrosion that remains on your copper wire. Mix the solution together until the salt is well incorporated with the vinegar.
Allow the wire to sit in the solution. As the wire sits in the solution, the corrosion should loosen on the wire and make it easier to scrub off. Let the wire sit in the solution for anywhere between 10 minutes up to an hour.- Scrub the wire with a nylon brush or sponge. Remove the wire from the solution and place it on a flat surface. Use a nylon brush or a dish sponge and use the solution to wash the wire. The salt should act as an abrasive that can aid the process of removing corrosion.[7]

About This Article
You can clean copper wire in just a few minutes using some basic household cleaners. Before you clean the wire, you’ll need to strip the plastic casing off. Place the wire on a cutting board, then make a horizontal slit at one end with a sharp knife or razor blade. The cut should go all the way around the plastic, but make sure you don’t cut the actual wire itself. Once you make this cut, you should be able to remove the end of the casing, exposing the wire. To clean the copper wire, first, mix together 1 tablespoon of salt with 1 cup of vinegar to make a cleaning solution. Let the wire soak in the solution for 10 minutes to an hour. Then, use a nylon brush or sponge to scrub off any corrosion or dirt. Once you’ve removed it, rinse the wire under cold water then pat it dry with a cotton rag. To learn how to strip copper wire in boiling water, read on!
