I've been brewing some fruit beers and I have several PET carboys with junk on the inside shoulders. Below the neck but above the carboy walls.
These carboys are really nasty in this area, with stuck on yeast krauzen, cinnamom, molasses, etc.
I build a high pressure/flow keg/carboy washer with a spray ball. I use PBW in it. It gets everything but the shoulders clean. I built a special fitting that sprays only the shoulders of the carboy. Still doesn't get it off. I built a spinning shammy thing that I use in my drill. Won't reach that area because the neck interferes with the spinning of the cloth.
How does one easily clean the shoulders of a plastic carboy ?
Thanks
