My time at RAF Cosford 1959-61, 16 yr old Boy Entrants in wooden huts cleaning linoleum floors with paraffin prior to applying polish and then bumpering the lino to a high gloss. What could possibly go wrong? Other character-building tasks included polishing metal dustbins (interior as well as exterior) with Duraglit or Brasso and using razor blades to scrape handles of brooms and bumper until they were "clean"
