16 Cleaning
Regular cleaning of the (easy to clean) interior prevents the
formation of deposits which may impair the appearance and
function of the oven.
The unit can be cleaned with a commercial stainless steel cleaning agent. Please note
that objects liable to rust must not be placed into the interior. Rust deposits lead to
contamination of the interior or the external casing.
If any rust stains appear on the interior surfaces through contanimation, the affected areas
must be cleaned and polished immediately.
Warning !
Do not use cleaning fluids containing scouring agents or solvents for cleaning the
operating module, the plastic trims or other plastic parts.
