I have buckets from Austin Homebrew Supply. The underside of the lid is ringed with grooves just inside the gasket. A vigorous fermentation leaves deposits inside these grooves, and it is virtually impossible to remove all of the gunk. Three questions:
1) Should I even be worried about this?
2) If so, any suggestions of how to clean the lids? I've tried soaking in PBW and using Q-Tips, to no avail.
3) Does anyone know of a vendor that sells buckets with smooth lids? The grooves serve no purpose that I can discern. I don't know why Austin would sell a fermentor that's so difficult to clean.
