Denture cleaning tablets do amazing things.
The effervescence seems to go places where scrubbing can't. Might be worth a shot.
tj99959 had the best advice: get a couple more tanks and dedicate each to a specific flavor type. Fruits, baked goods, coffees, candies, & mint/cinnamon/anise should be a good start.
Only people vaping your specific brand & flavor can tell with any certainty that its taste can effectively be completely cleansed from your tank.
Good luck.
