To fix a burnt elf bar, start by soaking it in cold water for about 10 minutes. This will help cool the metal and make it easier to work with. Next, use a fine-grit sandpaper to gently remove any remaining burnt residue and restore the surface to a smooth, even finish. Finally, apply a small amount of lubricant to the bar to help prevent future rust or corrosion. With a bit of patience and care, your elf bar should be as good as new in no time!
