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: 
Squeeze out a lemon get some baking soda and some toothpaste mix it together and apply to the cord and take a wet paper towel not too wet and remove the mixture and there you have it good as new.
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.
