Ok, I admit, this is an unusual one, but each time I squirt dishwashing liquid onto a cloth or a sponge to wash up, I am reminded of our friend Christian and transported straight back to his very cool batchelor pad with the spiral staircase on Portobello Road in Notting Hill. As I helped Christian wash up after a lovely lunch at his place, he went on to tell me how he had solved a problem that had been bothering him ever since his brother had moved in. Christian had noticed they were going through three times the amount of dishwashing liquid than usual, so he got to thinking. He hypothesised that instead of squirting the dishwashing liquid directly onto the sponge, holding the dishwashing liquid for longer, therefore washing more items per squirt, that his brother must have been squirting the liquid directly onto the dirty dish in turn washing the liquid down the drain. With his hypothesis in mind, he observed his brother washing up was proven correct meaning It was a simple matter of technique that would make the washing up process more efficient and economical. Problem solved.
