How to clean battery corrosion in your old electronic devices

If you have old electronic devices lying around, chances are you’ve come across battery corrosion at some point. Battery corrosion can cause your devices to malfunction or even stop working altogether. It’s important to clean it up as soon as possible to prevent further damage. Here’s a step-by-step guide on how to clean battery corrosion in your old devices.

How to clean battery corrosion in your old devices

Step 1

Safety first Before you begin cleaning the battery corrosion, it’s important to take some safety precautions. Firstly, make sure the device is switched off and disconnected from any power sources. Wear gloves and eye protection to protect your skin and eyes from the acid in the corrosion. If the corrosion is particularly severe, consider cleaning it outside to avoid inhaling any fumes.

Step 2

Remove the battery The first step in cleaning battery corrosion is to remove the battery. If the battery is still intact and hasn’t leaked, use a small screwdriver to carefully remove it from the device. If the battery has leaked, use a pair of pliers to remove it to avoid touching the acid.

Step 3

Clean the battery compartment Use a dry cloth or brush to remove any loose debris from the battery compartment. Next, mix a small amount of baking soda with water to create a paste. Apply the paste to the corroded area using a cotton swab or toothbrush. Leave the paste on the corroded area for a few minutes to allow it to penetrate the corrosion.

Step 4

Scrub and wipe Using a toothbrush or cotton swab, scrub the corroded area until the corrosion has been removed. Wipe away any excess paste and corrosion with a dry cloth. If the corrosion is particularly stubborn, use a small amount of vinegar to help break it down.

Step 5

Rinse and dry Once you’ve removed all the corrosion, rinse the battery compartment with a small amount of water. Wipe it dry with a clean cloth or leave it to air dry for a few hours before reinserting the battery.

Step 6

Dispose of the battery If the battery has leaked, it’s important to dispose of it safely. Put the battery in a plastic bag and seal it before disposing of it in a battery recycling center or a hazardous waste disposal facility.

Tips and Precautions

Here are some additional tips and precautions to keep in mind when cleaning battery corrosion in your old devices:

  • If you don’t have baking soda on hand, you can use a commercial battery cleaner or a mixture of lemon juice and salt instead.
  • Avoid using metal tools to clean battery corrosion as they can damage the device. Use plastic or wooden tools instead.
  • If the battery corrosion has spread to other parts of the device, such as the circuit board, it’s best to take the device to a professional repair shop to avoid causing further damage.
  • Always dispose of batteries properly. Don’t throw them in the trash as they can leak and cause environmental harm. Look for a local battery recycling center or hazardous waste disposal facility to properly dispose of them.
  • Regularly check your electronic devices for signs of battery corrosion. Catching it early can prevent further damage to the device.

In conclusion, cleaning battery corrosion in your old devices is a simple process that can save your devices from further damage. Remember to take safety precautions, remove the battery, clean the battery compartment, scrub and wipe, rinse and dry, and dispose of the battery safely. With these steps, your old devices can work like new again.
