I never had an IN-1 run long enough to get poisoned. Mine developed internal shorts, resulting in 2 numerals glowing at the same time. >From what I've heard, nixie degradation increases exponentially with current, so you want to stay as close as possible to normal operating current. Try running the worst digit continuously for a few hours at 20% higher current, and see if that helps. I was (briefly) drawn to the IN-1 over 10 years ago because of the large size for the low cost; I bought a case of 25 for around 40USD including shipping. Only a few survive today that weren't dissected or tortured in a microwave oven (yeah, pretty hilarious but kinda toxic because of the bakelite).
A few of the IN-18's in my clock have shown signs of poisoning even though I run a cleansing routine for 1 hour every night. This is most-visible on the first day of the month for the months digit, and it can take a few days to recover. This clock has 14 tubes; kinda ridiculous but it looks impressive. It was inspired by the movie "Tomorrowland", which has a brief scene with two 6-digit IN-18 clocks. I'm certain one of our neonixie members is the creator of that clock (that was an invitation for you to take a well-deserved bow...). Tubes that run 0-9 during the day need no cleansing (unit seconds, unit minutes, unit hours). Tubes the run 0-5 during the day are cleansed by running 6-9 (tens seconds, tens minutes). Tubes that are static, or near static (tens hours, month, day, year) run 0-9 for cleansing. The static tubes, notably the 4-digit year, show very little signs of poisoning because I have swapped them around to put the most-vulnerable-to-poisoning tubes where they run 0-9 during the day. I havn't seen any signs of poisoning on Burroughs tubes.
