It might sound odd, but the key to keeping your car running smoothly and efficiently is a good battery connection. Without a good connection, the combustion engine, as well as other electrical accessories, won’t run as smoothly as the manufacturer intended.
Thankfully, it’s easy to spot when your connection terminals need cleaning with a simple visual check. You’ll notice a few specks of crunchy white residue, or in the worst case, a blue powder-like substance caked on the terminals.
To get rid of corrosion, simply remove your battery terminals (remember: negative cable first!) and clean both the battery terminals and posts with a battery cleaner solution. Give them both a good scrub with a wire brush until all corrosion is gone, then use a cloth dampened with water to wipe them down properly.
Before putting everything back together, use a dry cloth to ensure all terminals and posts are free of moisture. You can now reinstall and tighten the battery terminals!
