It may be possible to repair the original pot.  Where cleaners and solvents have failed, I've fixed worn pots by bending the wiper slightly to contact an unworn area of the resistance element.  Among other situations, this worked well to restore correct operation to a friend's car - engine trouble was caused by airflow sensor resistance element wear (airflow sensor is a spring loaded vane mechanically coupled to a pot's shaft).

Of course, if you have a circuit failure and end up smoking the pot, all bets are off.  Woe be to he who smokes pot!
