1. I am not sure that dishwashers were ever meant to clean every bit of potato, carrot, rice, sauce, dried-in-meat, stale curry plates, mustard stains, etc from every plate, saucer, cup, fork, knife, spoon etc.
2. If there's one thing that's policed in the Leper household, it's the electric dishwasher (and me being the human version). Mrs Lep (traditional Cork lady who previously advised her maternity consultant on how time in labour should be executed properly) demands that each piece of crockery (bought in Roches Stores and The Munster Arcade, of course) should first be rinsed and if necessary brushed under a flowing tap before being placed in the dish-washer in order of size etc (Philips Dishwasher from Phil O'Sullivan's, natch!).
3. Her results are terrific, no grime, no residue, less salt use, less whatever and cleaner dishes and cutlery (Newbridge you know!).
