Swanmaid
Apologies for resurrecting this ancient thread, but...
I was watching an old colour film from 1969/1970, called 'Some Will, Some Won't'. This film is an inferior remake of the 1951 Alastair Sim film, 'Laughter in Paradise'.
Anyway, in 'Some Will, Some Won't', Michael Hordern's character is tasked with doing some shoplifting in a department store, not very successfully I might add.
He enters the appliances section (a wall poster advertising 'Hotpoint Iced Diamond Refrigerators'), and walks past the floor-standing late-version 'Swanmaid' dishwasher (plain handle, 'Swanmaid' nameplate lower-left corner of door).
A metal canister - the size of a 'Dulux' paint tin - stands upon the 'Swanmaid' dishwasher. The canister seems to be silvery-grey, appears to depict a woman with an open dishwasher. The label on the tin apparently says 'Fen', in blue, with a red oval label partly covering the 'n'.
I am assuming that this was perhaps a Swanmaid detergent, ('The Fens' being the habitat of swans, etc).
Hordern's character tries to pinch a Rolls-Colston MkIV table-top machine, almost doing himself a mischief in the process.
I also came across this paper (dated 1966) about disinfection of surgical apparatus. Swanmaid is mentioned and tested, with 'Hygleam C' detergent - it is apparently P&G's 'Freedom ' detergent by another name.
