I'm either the most clueless dishwasher user in the world, or this is truly a UK-only dishwasher phenomenon! Regardless, after almost four years in this country, I'm still amazed at the things I learn on a daily basis.
We had a dinner guest over last nite, and in the course of pulling out a few wine glasses for drinks, Simon made the remark about how dingy the glasses looked. Our genius guest asked us if our dishwasher was just out of 'dishwasher salt', to which we both just sat there with what can only be described as 'huh?' written across our faces.
Our guest proceeded to hop up off the couch, walk into our kitchen & open our dishwasher. Where, in a matter of 2 seconds pointed out a covering in the bottom of the dishwasher marked 'Salt' (of course!) where you pour said salt.
Apparently, this is very common in the UK, but I've never heard about it until now.
