Scale Removal
The Raindance Air 1-jet handshower incorporates the
Rubit TM cleaning system. If scale deposits are noticed in
the spray channels, turn the water on lightly and rub the
spray channels with a finger or a sponge.
If scale deposits are noticed on the spray face, pour
about 3/4” of a commercial scale remover, such as Lime-
Away TM or CLR TM ,into a shallow dish. Dilute the remover
according to the label instructions.
Soak only the spray face in the solution for the amount of
time specified on the label.
Rinse the handshower with clear water.
Reinstall the handshower. Turn on the water and allow
the handshower to flush for at least one minute.
