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?
