Hi Toby,
Can't offer much in terms of your situation.Maybe alot of work with the Dyson.
Thought I would contribute to your post as I have just returned from seeing an old mate who is 70 and a bachelor since his divorce in the 1980's.Anyway his flat resembles something from the 1970's...Wicker book cases,lights with curly flex hanging from the ceiling,a Hygena G plan kitchen.You get the drift.Anyway the dust on ornaments and stuff is a given.We are talking decades !
He also has a big bottle garden but the contents have been dead in there for the last 15 years and its like a dusty hole in there.I think he does hoover but stops short of getting the duster out.He's got a wicked sounding valve SET system though with big Focals and just upgraded his TV to a Pioneer 4K 55" set which is one down from the top model in the range.Wicked picture.So hes got his man cave sorted entertainment wise.
