I found yet another use for my fave salad topping today - cleaning away battery contact corrosion.
Let me stress that this corrosion was not on a battery, but on a removable metal contact in a battery operated toy. I tried cleaning the corrosion off with a paper towel to no avail, and then discovered that the contact plate was removable, and therefor available to other cleaning methods.
Hmmm. What about soaking it in vinegar? I submerged it in a little glass bowl for about ten minutes, and then carefully wiped it dry. I reinserted it in the toy, added fresh batteries, and presto: it worked!
