Batteries are used for everything: remote controls, clocks, toys. However, after a while, the batteries can become dirty with sulfate.
Follow our instructions to clean this or any other sulfated item!
Steps to follow
Take the battery or device with the sulfated surface and moisten it with lemon juice, the amount necessary to moisten that area. Then brush the surface until the sulfate subsides.
Finally dry it with a cloth and put it back in the device.
