How to Clean Battery Corrosion in a Remote Control

Remote control batteries can get dirty over time. Corrosion can also leak onto the remote’s battery cover or terminals, this usually happens if the batteries are old. To avoid corrosion, change your batteries on a regular basis. Remember to always remove the battery from the remote when not in use. You should also note the expiration dates of batteries so that you can replace them in time, this provides optimal performance of the device.

You can use a pencil eraser or a toothpick to clean the contacts in the battery compartment. Also, you may also want to use a squirt of WD-40 to loosen any large amounts of corrosion. Make sure you wear gloves to protect your hands, this is because an alkaline battery has a liquid electrolyte that can break down over a prolonged period of time.
The corrosion can be dangerous for your skin, eyes, and lungs if it’s inhaled. Hence, be sure to use gloves, safety goggles, and a face mask while cleaning. Make sure to work in an area that has plenty of ventilation. If you’re planning to clean battery corrosion in your remote control, be sure to follow the manufacturer’s instructions carefully or check their website if applicable.

If you can’t clean the battery corrosion in your remote control by yourself then you can just try replacing the batteries. Replacement batteries are relatively inexpensive and easily available at Walmart.

If you want to get the best battery life out of your remote then it would be better to purchase leakproof lithium batteries.

A common method to clean battery corrosion in remote controls is to use a solution of baking soda and water. The solution should be neutralized with potassium hydroxide.

While rubbing baking soda into remote control batteries isn’t a permanent solution, it does help get rid of stubborn corrosion. It can be applied using a cotton swab or a damp lint-free cloth.
