What can you use on battery terminals to stop corrosion?

Is there anything other than the red belt dressing that works well on the top post battery terminals to stop corrosion. After sitting over the winter with a battery tender, my 445 has some white powder around the positive side terminal. I cleaned it up last night since there was not much and I put a little baking soda and water, then rinsed.

I am out of the red stuff and wanted to coat it tonight, but I will not have time to run to the store. Anything else work that might be a household item?

I hadn't heard of the penny trick; but aren't modern pennies copper plated zinc? If so, the zinc would act as the sacrificial anode.
