         housekeeping relies on three basic
         principles.                                                      He continued, "For low pressure,

             ensure they are clean at the end of
             service, along with the rest of the
             equipment.

          Furthermore, "ensure the steam wand is
         properly purged before and after each
         milk foaming session and wiped clean.
         Never let any milk solids accumulate.
         Also, check the calibration of your grinder
         using scales and timing. The shot times
         and gram throw should always be
         consistent; if not, adjust the grind and
         throw accordingly. If possible, complete
         this daily and record your results."

          Typically, all staff should be able to
         perform basic daily cleaning; it will help
         them understand the principles that
         support flavourful coffee extraction and

         freshness for each beverage prepared.
