Am I the only one that views a BB as a "consumable"?

Replace it, now - simple. Eliminate it as a problem.

If the noise persists, it's something else; but you've created "ground zero" for your BB (mark it down in your "consumable" diary).

My experience with "it's been done recently" means anywhere from 2 to >5yrs ago. People's perceptions can be all over the shop.
