maintenance
general
Clean the extractor hood at least once a month. Clean the
grease filters at the same time.
You should clean the stainless steel or painted exterior of
the hood with a solution of washing-up liquid and a damp
cloth. The stainless steel will regain its shine if you
occasionally use a stainless steel care product or polish.
The polish imparts a dirt-resistant layer to the stainless
steel. Always clean the stainless steel in the direction of
polishing.
Never use abrasive cleaning agents, green scouring pads or
other scourers or polishing cleaning products (such as liquid
scourers).
Do not use aggressive cleaning agents. They can discolour
the stainless steel or attack the paint.
