Each brand is different and comes with detailed instructions that you should read and then follow to the letter.

Generally, you spray the cleaner on to the terminals and cables and wipe the corrosion away. Chemical cleaners - there are many brands available, and you can easily find options at auto parts stores or a retailer with an automotive department.
AUTOZONE BATTERY ACID HOW TO
When it comes to how to clean a car battery, there are two popular methods: store bought chemical cleaners or the greener, homemade method.
AUTOZONE BATTERY ACID MANUAL
Always undo the negative cable first, then the positive cable (important: refer to your vehicle owner’s manual for instructions).Make sure the engine is turned off and has had time to cool down.Before you attempt to do it yourself, remember safety first! We’ve explained why car battery corrosion is bad. Corrosion can prematurely damage and even destroy the battery post(s) and, if you want to keep rolling, you may need to replace your battery sooner than you expected had you’d just taken the time to clean the car battery terminal. The average life expectancy of a new battery is four to six years.

This one will hit you square in the wallet. If you don’t pay attention and address these issues promptly, you could find yourself stuck on the side of the road with a dead battery. You’ll begin to experience problems like slow cranking during start-up, dim or weak lights, a clicking sound when you turn your key in the ignition or press the starter button. Corrosion is a poor conductor of energy, so if it’s allowed to build up, the battery can’t function as it should. The battery stores the electrical energy the starter motor and alternator need to operate. That acid mixes with debris and moisture in the air under the hood and corrosion naturally occurs. Contained within this off gassed hydrogen is a minute amount of acid from within the battery. Off gassing of hydrogen normally occurs during battery charge and discharge.

But don’t ignore it, either! Because of the essential role the battery plays in your vehicle’s starting and charging system, it needs to continuously operate at an optimal level. It’s a common problem that’s not hard to fix. It’s corrosion, and it happens over time because of the battery’s chemical structure.ĭon’t panic. You pop the hood, and there it is: chalky white flakes, or green or blue material on the battery terminals. Or perhaps your vehicle is suddenly slow to crank. Maybe one evening you notice your vehicle’s headlights are a little dim.
