  I don't think MS70 will do anything for carbon spots, its basically just a soap solution. What type of coin is it?- copper/silver/gold?

  I've learned that on copper attempting to remove a carbon spot is a fool's errand.

  From my experience the odds are against you. MS70 is a soap, originally designed as a golf-ball cleaner for industrial use (golf ranges) and does a reasonably good job on Morgans (and BU WarNicks in particular) in removing haze and light film. I've had some enormous success on some coins, and others (Commems) have just been restored to the 'as minted' look that doesn't go over so well at the TPGs when you are looking for higher grades (yup, I blew it and made 3 66s into 65s.).
  
  Bottom line . . . you can always dab a touch of MS70 on the coin on the end of a Q-Tip, but ANY type of rubbing action necessary to remove a carbon spot will hairline the coin. When you use MS70, a light rolling action with the Q-Tip is a must; any type of rubbing motion has a good chance of hairlining a coin.
  
  MS70 will give some (usually) good results on Morgans & other BU silver, but DO NOT use it on copper, circ. silver, or any coin where you'd like to leave the original toning and 'skin'. Just my experience.

  Suggest you dip the tip of a very sharp needle into the MS70 and then aggressively rub the tip of the needle over the carbon spot. Then thoroughly rinse the coin in warm water. The spot should then be gone.

  I have not heard of a successful method to remove carbon spots... at least not without leaving an altered surface. Cheers, RickO

  I happen to know for a fact that MS70 disolves carbon. What coin we talking here? Silver, copper? I used MS70 on a 79 type 2 dcam proof linc. Abe had a HUGE carbon doodie on his chin, so I popped it into a shot glass with pure MS70, which after 6 hours it ate the carbon right off the coin. I rinsed the coin and put in a flip. After 2 days a dark red streak appeared on the rev that just didnt look right. So carbon gone, but liquid mirror surfaces forever wrecked by streaking
