How to clean an aluminium stove top coffee maker?

[bluegeranium]

I have a Bialetti stovetop coffee pot which has become badly discoloured. Does anyone know the best way of cleaning it?

I haven't done anything yet as I seem to remember that there are quite a lot of things you're NOT supposed to do like putting in dishwasher/scouring it etc.

thanks
