I have a growler from a brewery that I love that I had to decommission due to beer stone deposits about a year ago. The thing is, they redesigned their growlers since I bought this one, and I hate the new design.
Now, they put a seasonal beer on tap this month that I fucking love (an Imperial Alt. Ale, 11% ABV and very sweet, with a really nice finish) and I want to bring some home. Of my options, finding a way to clear out the beer stone is the one I prefer, so what is that way? I've soaked it in soap and water and vinegar solutions in the past, but they had minimal effect. Today I got fed up, bought a gallon of vinegar, and poured the growler full of it. My plan is to leave ti soaking for a while, but I am worried that alone won't do it.
So please, help me out. What should I be doing to clean it? Also, what should I do once it is clean to keep this from happening again?

A beer stone is actually similar to a kidney stone, but it forms inside the beer is kept in. Which is an issue since it ruins new beer put in there.
Have you tried breaking it up with a tool?

Might be a bit pricey to get your hands on the lovely caustic chemicals involved though
