In preparation for the typical midwest winter, I replaced my old battery and seriously corroded terminal connections.
After cutting off the connector and stripping back enough insulation for the new connector, I wondered "How the Heck am I gonna get a good connection with all this GREEN corrosion on the wire???"
I knew that most soda pops have some mild acid content to them but I needed something stronger than a Coke Classic...
How about vinegar???
(I forgot to take pics of how terriffic vinegar was on the green corrosion so I am simulating it here with a piece of copper tubing. Please suspend your disbelief for a few moments
I went to the kitchen and found a bottle of white vinegar (5% acidity) along with a small Tupperware(tm)-like container to dip the stripped copper wire ends in.
Here is how it looked at first.
After 20 minutes, the tube finally gleamed all copper-y.
I have to say that the vinegar worked MUCH FASTER at stripping the green corrosion away. It took less than two minutes to turn the formerly corroded stranded copper battery wire to a bright reddish brown. It took nearly 20 minutes to get the results pictured below on the pipe:
I imagine that you can use this to clean up grounding wires and other tarnished wires that you are going to splice with a soldering gun.
Give it a try!
