Tom, If the K2 SN is below SN 3000, then I would suggest the Alternate AF Gain wiring mod be done. If the pot still is noisy, then replace the pot. For SN above 3000, just replace the pot. The use of cleaners is "iffy" IMHO - if the pot is worn, no cleaner in the world will help it on a permanent basis - any improvement will be short lived. Besides, it is difficult to ge any cleaner inside the pots used in the K2.
