DIRECT STEAM KETTLES

CLEANING

 The kettle and its parts are hot. Use care when operating, cleaning or servicing 

the kettle.

The kettle interior and exterior should be thoroughly washed after each use when a different food is 
to be cooked next or when cooking is completed for the day. If the unit is used continuously through 
the day, it should be cleaned and sanitized once every 12 hours.

Empty the kettle. Close draw-off valve and add water to the kettle for cleaning to prevent residue from 
drying and sticking to the inside of the kettle.

•  Never use harsh or corrosive cleaning chemicals.

•  Never scrape the inside of the kettle with abrasive cleansers, metal tools or steel scouring pads, 

which will scratch the surface, spoil the appearance and make it more dif

fi

 cult to thoroughly clean.

•  Add mild, non-chlorine, non-chloride, and non-bleach detergent and scrub the kettle interior 

with a nylon brush.

•  Loosen stuck-on food by allowing it to soak at a low temperature setting.

•  Thoroughly rinse the interior and dry with a soft cloth.

•  Rinse the exterior and dry with a soft cloth.
