My apple earphone cable is infected with iodophor a little yellow how to clean?

Pour a small amount of prepared medical alcohol into a plastic container.

Cut the medical gauze along the center scissors.

Then fold with gauze and dip in medical alcohol.

With gauze in hand, wipe and clean from the middle part of the earphone to one side.

Then wipe and clean from one side of the headset to the other. This will clean up the yellowed earphones.
