When I was in college I had to go to Atlanta for a work conference. I had an old Honda Prelude with over 100K. Anyway, one morning trying to run my car nothing, the battery seemed dead, so I had to call AAA.
The mechanic came right over looked at the battery and the terminals were pretty corroded. He took some change out of his pocket and just said to me, "Get me a Coke". My thoughts were WTF what I am your servant. I did not say anything, since I was away from home (at the time was living in Jacksonville, Florida) and needed to get back. Anyway, I came back with the Coke from a vending machine, next thing I know he is pouring the Coke on the Battery terminals. It was amazing on how it just ATE
the corrosion in the terminals making them all clear.
He then proceed to jump my car and I was able to get home. I was shocked at seeing that, and imagining what it was doing to my stomach. Anyway, I do not drink it, seldom do I do once in a while when I need sugar, but I still remember that day.
