Don't know about the UK, but that's pretty common in Germany, too. I'm one of the few who actually rinses the dishes with clear water afterwards. But it's not really necessary to do so. Detergents are designed in a way that there is usually only minimal residue. If you'd lick your dishes clean after every meal, you'd ingest perhaps 100 to 150 mg per year. Not really dangerous.Originally Posted by lexico
