Steel extractor hood frame (source MFI c. 2 years old) all too readily attracts unsightly and very visible dust.
The hood is earthed via the power supply to the fan. It is built in - bolted to the wall and does not connect with anything else metallic. Extracted air is blown outside via a plastic tube enclosed in a plasterboard/timber frame.
The frame is painted (probably stove finished) dark brown.
Visible dust starts to settle within an hour or so of it being wiped clean.
Is this why unpainted stainless hoods are popular?
TIA for all suggestions.
