Cleaning an extremely corroded Bronze Bell, PART2!

Giving the bronze bell another 15 minutes of vibrations to remove the corrosion, will it work?
Mixture used during this clean:
100% Water
a drop of dish soap
Temperature 50 °C

Definitely got a few crusty bits off.. maybe a little citric acid in the water might speed up the process a bit...

Its a nice thing to experiment different solutions on thanks for the idea.
