This right here is WHINK which is the secret to cleaning any of your (oil burners) pipes! First rinse with water then dump it out. After you add a small amount of this into it. Use a torch (must be a torch) and light it carefully under the pipe as if you were smoking it. You will soon start to see all the burnt black residue come right up. After with warm water rinse it out really good. If there is anything left inside a Qutip will wipe it right up. Dry it and it should look brand new! Hopefully this helps and makes things much easier for you.
