How do you fix a horse helmet with a scratch on it?

To fix a scratch on a horse helmet, first clean the area around the scratch with a mild soap and water solution to remove dirt and oils. Depending on the depth of the scratch, you can use a fine-grit sandpaper to gently buff the area, followed by a polish specifically designed for helmets to restore its shine. If the scratch is deep or affects the helmet's safety features, it’s best to consult a professional or replace the helmet to ensure safety. Always prioritize the helmet’s integrity over cosmetic repairs.
