This replacement part comes with 2 pads and 4 washers for the carboy cleaner. Eventually when your original pads have cleaned enough carboys and kegs, they'll need to be retired and replaced by a set of these new ones.
The carboy cleaner is constructed of a stainless steel rod with two super absorbent, lint free, soft cleaning pads to wipe carboy walls clean without scratching them. High-strength, yet flexible plastic inserts inside the pads help keep the pads rigid during use. The expanding sponge at the end of the cleaning pad assists in the centrifugal cleaning force for tough to get debris.
