Default ques about plug chop

if you've been using the spark plug a little and the motor was running rich (black plug).
... and then you re-jetted, soaked the plug overnight in carb cleaner and laquer thinner, would you still be able to get an accurate reading or will the black color that is baked on to the plug forever mask any other reading?
