Ok, so I know you're not supposed to, but my mum had a very gung-ho attitude to puting things in the dishwasher and washing machine and she never seemed to bugger anything up...
Anyhow... my lovely (newish) shiny hob-top expresso maker is now dull and makes a horrible screeching sound when you screw to top on. DH won't be happy as he bought it for me as a present (I love my coffee in the morning). Any suggestions? I tried buffing it with the stuff I use on the cooker hob, but no luck. Or do I buy a new on (there goes £25) and pretend that I just gave it a really good wash?
