Oxygen-starving abrasives such as hydrochloric acid, chlor-
ides and spice concentrates, mustard, vinegar essences,
spice cubes and cooking salt solutions can lead to chemical
damage or rupture of the passive layer, depending on the
concentration and temperature.
Extraneous rust (iron particles), the formation of galvanic
elements and lack of oxygen could cause more damage.
If the appliance is kept in an environment with corrosive
substances (e.g. chlorine), it is advisable to apply a thin layer
of Vaseline oil to its cleaned stainless steel surfaces.
IMPORTANT
Keep stainless steel surfaces clean at all times and
make sure they are well ventilated.
Please follow these instructions:
• Remove grime, fat and other cooking residuals from steel
surfaces when cool using soapy water, with or without
detergent, and a cloth or sponge.
Dry the surfaces thoroughly after cleaning.
• In case of encrusted grime, fat or food residuals, go over
with a cloth or sponge, wipe in the direction of the satin
finish and rinse often.
Rubbing in a circular motion combined with the particles of
dirt on the cloth/sponge could spoil the steel’s satin finish.
• Metal objects can spoil or damage the steel: damaged
surfaces become dirty more easily and are more subject to
corrosion.
• Restore the satin finish if necessary.
• Do not let stainless steel parts come into prolonged contact
with acids, spices, salts, etc. Even acid fumes which build
up from cleaning tiled surfaces can promote corrosion.
Rinse off work surfaces with fresh water. This applies
especially after cooking potatoes, pasta or rice in salted
water.

Colored surfaces
• Clean all colored surfaces on a daily basis.
• Use soapy water and a cloth to remove food particles and
grease
• Metal objects can spoil or damage the surface: damaged
surfaces become dirty more easily and are more subject to
corrosion.
• Do not let colored surfaces come into prolonged contact
with acids, spices, salts, etc. Even acid fumes which build
up from cleaning tiled surfaces can promote corrosion.

J.6
Gaps and Joints
Use the plastic scraper supplied with the appliance to remove
persistent soiling in gaps and joints.
Then remove dirt, food particles and grease with soapy water
and a cloth or soft sponge.
Always work in the direction of the satin finish to prevent
damage to the steel surface.
J.7
Descaling
WARNING
Refer to A.2
IMPORTANT
Remove limescale, fat, starch and protein layers
with regular cleaning to avoid corrosion.
• De-scale the appliance with a solution of 10% vinegar, 10%
phosphoric acid or a suitable de-scaling solution available
for purchase.
• Never use steel wool or other abrasive materials which can
scratch the surface of the stainless steel.
