De ce să aplici suc de lămâie pe baterii? Ai nevoie de o dischetă demachiantă și puțină răbdare • Newsweek România

Using lemon juice can effectively clean battery contacts that have lost their shine or developed stains. The citric acid in lemon juice helps remove dirt and corrosion from metal surfaces, improving electrical contact. To clean, remove the batteries, apply a small amount of lemon juice to a cotton pad, and gently wipe the contacts. Ensure the pad is not soaked to prevent liquid from entering the device. After cleaning, let the contacts dry completely before reinserting the batteries. If a battery is damaged or leaking, it should be replaced rather than reused.
