In my 35 years of repairing electronics, my success with "cleaners" has been much lower than 99%. I'd rate it closer to 5%, but even when there's success, the problem always returns. You can't find a genuine cleaner, either, since trichlorotrifluoroethane has been outlawed for consumers. Cleaning a pot is like sprinkling salt on a bird's tail: if you've gone to the trouble to get that close, just reach out and catch the bird. Moral, try the cleaner (whatever that is), but while you're in there, replace the pot.
