Either use Alcohol or Nail Polish Remover. It comes right off. But don't use anything stronger.
This is what you need.
1. Rag or old T-Shirt
2. Clean towel
3. Rubbing Alcohol or Nail Polish Remover (Quicker Results)
This is what I did.
Pour some Nail Polish Remover on the Rag and whipe the backside of the Needle. (NOT THE FRONT) The paint comes right off. Make sure once you whipe the needle with the Rubbing Alcohol or Nail Polish Remover. You clean it right after with the clean towel because you don't want to burn the needle. I would recommend the towel being moist. You will notice you are burning the needle when it starts turning white. Keep on doing this until the needle turns clear.
