Battery terminal protector instead. I've had the same can for about 8 years. It has lasted many a car.
Clean the terminals and clamps with a wire brush, spray a coat of the protector on everything and add some fiber washers. I've never had terminal corrosion issues.
Clean it up good then you can use anti-corrosion washers or [anti-corrosion spray](https://www.amazon.com/Permatex-80370-Battery-Protector-Aerosol/dp/B000BOKML2/ref=sr_1_2? s=automotive&ie=UTF8&qid=1496404545&sr=1-2&keywords=anti+corrosion+spray) or just coat them in a heavy grease after you retighten.
The corrosion is caused by the dissimilar metals and perhaps a bit by the hydrogen gas generated when charging the battery.
Get something like this from your local auto parts store, or even Wal-Mart. I had a car that had corrosion issues on the battery terminals and after cleaning with a wire brush, baking soda and water (as others have stated) I put these on and they never corroded again. Cheap investment, worked perfectly.
