Question: I've found a good-condition earphones in an old bag, and I've managed to clean the earphone cords with a rag and alcohol, I've also found **[this video](https://www.youtube.com/watch?v=tVeH2rhocSY)** which suggests to clean them with **Window Cleaner Liquid** which also helped me remove the last dirty of the places that alcohol couldn't remove it.

But on the plugin area, I can't seem to remove the "yellow" color. How can I clean this yellow area?

Answer: 
Just use a little bit of hand sanitizer and keep applying it over the length of the cable over and over again. It has left my earphone cables looking almost new.
use white toothpaste :) it works on my white earphone turned yellowish
