How To Clean Battery Corrosion
Have you ever wondered how to clean battery corrosion (or even if it's possible to do so)? Yes, it is possible to clean mild to moderate battery corrosion -- and as I'll show you, it's actually really simple too!
- Paper towels or cleaning rag
- Cotton Swabs
- Baking soda
STEP 1: Remove and discard old batteries.
In almost all cases of battery corrosion, you'll need to dispose of the old batteries.
In my experience, it's fairly easy to clean the corrosion off the toy or other electronics, but you can't really "clean" it off the batteries.
STEP 2: Wipe out any loose chunks.
Sometimes you won't need to do this, but if there are any loose chunks of corrosion, I try to wipe those out with a damp paper towel (or blow them out with a can of compressed air).
STEP 3: Make a paste of baking soda and water.
You'll only need a teaspoon or so of baking soda and just a few drops of water.
I use a cotton swab and a small bowl to mix it into a paste.
STEP 4: Rub the paste onto the corroded areas.
Using the cotton swab, simply rub a small amount of the baking soda paste on and around the corroded area until the corrosion starts to rub off. Use new cotton swabs as necessary.
STEP 5: Wipe out excess with a paper towel.
Once you have the corroded area mostly cleaned out, use a damp (almost dry) paper towel to wipe the area. Then let it air dry before putting new batteries in.
STEP 6: Test it with new batteries.
Put new batteries in the unit and test to see if it works!
There have been a couple of times when this cleaning method has not worked for me, but for the most part, once I put new batteries in, the item works just like new again!

I know my quick cleaning tips won’t work for every case of battery corrosion, but considering the process only requires a few minutes and a tiny bit of baking soda, it doesn’t hurt to try!
BONUS TIP: If you plan to give a gift that requires batteries… include a pack of extra batteries! I know it will be appreciated 🙂
