Faucet internals are a distinct part of the dispensing system that a beer line clean alone doesn’t reach, as covered in our note on faucet cleanliness and pour taste.
Disassembly follows the specific faucet’s design
Most tap faucets are designed to come apart into a handful of components — follow the manufacturer’s specific disassembly instructions rather than forcing parts apart, since designs vary between faucet types.
Soaking in a dedicated solution addresses residue a rinse won’t
A dedicated beer line cleaning solution, the same kind used for line cleaning, is generally appropriate for soaking faucet internals — a quick rinse alone often isn’t enough to clear built-up residue from internal channels.
Thorough rinsing before reassembly matters
As with any cleaning solution used on dispensing equipment, thoroughly rinsing all residue before reassembling and returning the faucet to use avoids any lingering taste from the cleaning product itself.
What to do in practice
Disassemble per the manufacturer’s instructions, soak in a dedicated cleaning solution, rinse thoroughly, and reassemble — building this into the same regular schedule as beer line cleaning.
What we would not do
Rely on beer line cleaning alone to address faucet residue — the internal faucet parts need their own separate disassembly and cleaning step.
