I've yet to find a liquid solvent of any brand that will remove carbon, as verified with before and after use of my Hawkeye. Several that make advertising claims for their carbon removal abilities, are just plain outright lies! A few liquids will remove it from the flat surfaces on the lands & grooves, but will not take it out of the corners where the lands meet the grooves. "The Hawkeye knows".
