Persulfate can oxidize organic compounds at lower temperatures. I have no idea if that would still be too punishing for the electrode. You could probably monitor nitrate production of just persulfate in solution as a way to tell at what temperature a reasonable rate of oxidation is occurring. Just a thought, not a persulfate pusher.Nice.
Thinking about removal (to confirm the effect is external film/deposits).
I'm thinking toothbrush +
1) detergent
2) then if that doesn't work maybe solvent (ethanol)
3) then if that still doesn't remove the effect, acid (HCl or H2SO4)
