Critical reception
The Monthly Film Bulletin wrote: "Despite the promise of its credits Secrets of a Door-to-Door Salesman is a sex comedy which achieves the dual feat of being neither erotic nor funny in charting the progress of an innocent abroad in London. Joe McGrath's script lurches from one clichéd situation to another, and leans heavily for its humour on double entendres (really scraping the barrel when plodding through all the possible sexual innuendo to be wrung from the action of a vacuum cleaner), while any gags exhibiting signs of life are swiftly crushed by the actors who as with the exception of guest stars Graham Stark and Chic Murray as appear to have been selected less for comic talent than for a willingness to remove their clothes at regular intervals. Altogether, the film marks an inauspicious return to feature films by Wolf Rilla, and it is difficult to believe that this feeble romp was directed by the same man who made the imaginative Village of the Damned [1960]."
