How To Get Rid Of Battery Corrosion

Battery corrosion can occur when batteries are left in the device for a long time. The batteries can leak of alkaline acid that later on builds up inside the battery slot for your device or gadget. You will know that battery corrosion happened if you find in the battery slot white chalky residues that may be in form of dust or liquid. These materials caused by battery corrosion are quite dangerous so be careful when dealing with them.

If you have found leaky battery corrosion residues in your device, you should clean and remove it as soon as possible to prevent further damage. Remember that if you found the forming alkaline acid just in time, you may prevent your device from getting wrecked. In order to properly get rid of battery corrosion, here are some useful tips for you.

Gear up properly

First and foremost, you should wear proper clothing and dress before you start cleaning alkaline battery corrosion. As mentioned, these residues can be harmful and can cause accidents so before you start getting rid of battery corrosion, wear old clothes that cover most parts of your body, use gloves and eye protector.

Get some apple cider vinegar

Because alkaline residues are acid and apple cider vinegar is a base, it can help in neutralizing the chemical contents of the battery corrosion residue. Get a cup of apple cider vinegar and a cotton swab. Using the swab dipped in apple cider vinegar, rub the battery corrosion so that the concentration of the acid will be lessened. Repeat this method about five times within a couple of minutes.

Clean the corroded area

After you have neutralized the acid with the apple cider vinegar, you can now clean the corroded area. In order to avoid any unwanted spills, do the cleaning over your kitchen sink or outside the house. Baking soda can help clean battery corrosion well. Simply dilute baking soda in water and get a piece of cloth or old dishwashing scrub. Soak the cloth in the baking soda and water solution, and then clean the corroded area thoroughly.

Rinse with water

Once you have cleaned the corroded area with baking soda, you can once again take a clean cloth soaked in clean water and use it to remove any residue of the baking soda and water solution. You might have to repeat this step a couple of times to make sure that no dirt will be left to accumulate.

Pat dry

When you have finished cleaning and rinsing the battery corrosion, you can now get some cloth and pat the device dry. Be sure that every corner and side has been dried up to avoid causing further damage to your device or gadget.

Prevent battery corrosion

If you do not want to deal with battery corrosion again, you should know how to properly use your batteries. If you are not going to use the device for a long time, then take out the batteries and place them in a clean safe place.  Do not put together batteries of different kinds and do not mix up old batteries and new ones for your devices. The difference can have an effect on the operation of the batteries. Also, do not place batteries in the refrigerator. A lot of people believe that placing the batteries in the refrigerator can prolong their life but it actually just causes it to become more prone to become leaky.


  1. Andre Said,

    Apple cider vinegar is an acid, so I am a little confused about that part of the article. Other than that paragraph, the artice seems quite useful.

What worked for you?
