The next time you face a sticky situation caused by a battery leak, follow these steps to clean up the mess safely and effectively.Photo: istockphoto.com All batteries—particularly the alkaline variety—leak over time, whether drawing a current or not. So even if you heed the expiration date listed on the package, you can end finding your batteries corroded, if not within the battery compartments of home electronics, then in the junk drawer where you like store extras. With alkaline batteries, leaks usually manifest near the contacts as a white and flaky substance. To clean battery corrosion like this, follow these easy guidelines. Photo: fotosearch.com How to Clean Battery CorrosionSTEP 1: Protect yourself and your work surface.First, set up a safe place to do the job. Spread newspaper over the surface where you plan to work, and since there are chemicals involved, it’s recommended that you wear protective gear. STEP 2: Clean battery corrosion with a household acid, like vinegar.Alkaline batteries leak, not acid, but a chemical that registers as a base on the pH scale. For that reason, it’s wise to clean a battery leak with a mild household acid like vinegar or lemon juice. Both liquids work to neutralize the alkaline discharge. Place a drop of vinegar or lemon juice onto the corroded area, then wait a minute or two for the neutralizing effect to take place. STEP 3: Use a Q-tip to wipe up the corrosion.Having dipped a Q-tip or toothbrush dipped into your chosen acidic liquid, gently wipe away the crystalline white residue from the battery itself and wherever the leak may have spread. Double-check the drawer where you store them and the compartment in battery-powered device so that you don’t miss any of the residue. Again, be careful not to get the chemical on your skin or in your eyes. STEP 4: Pick out the last of the crystalized leak with a toothpick.Address lingering residue with a toothpick or, even better, a pencil eraser. If you’re cleaning the contacts within the battery compartment, sandpaper or a file may prove handy for the purpose. Now, what do you do with the batteries that have corroded? Some municipalities allow you to throw in alkaline batteries with your regular trash. Other counties and states enforce more stringent regulations. Check with your local sanitation department for the appropriate disposal method.
