Our new house is a 1960s standard construction property. Some of the rooms are very smelly and the smell is that of urine (cat or human or, most likely, both). The house is in good nick but hasn't been well looked after (elderly couple who couldn't cope with a too-big house, that sort of scenario).
We've had the carpets cleaned by an industrial company and that has helped and certainly the carpets must be pretty clean now, but still the smells linger.
Has anyone any good tips on how to remove the odours? We could spray Dettol (or similar) everywehere to "drow out" the pervading smells but that is more masking than removal. I hope we don't need to lift up the now-clean carpets in order to scrub the underlying floorboards, but is it anyone's experience that that is likely to be the necessity?
thanks for any pointers - we've got a good book from Channel 4's "How Clean Is Your House?" which has some tips but I am after any other thoughts too please.
