@clacke @aprilfollies @NamelessCynic In the UK, yes, “washing up” is normally hand washing as opposed to machine washing, though I wasn’t fully aware of the usage till I visited about 5 years ago. I’ve never heard of people in the UK accidentally putting “washing-up liquid” in the dishwasher. The US, where I live, calls the machine version “dishwasher” liquid or detergent, which is fine, but the hand washing version is “dish” detergent, which, as many new apartment dwellers and home owners discover the hard way, is only suited for “dish” washing by hand and utterly unsuited for “dish” washing with a machine.
