apologies for the bad spelling, does anyone know how i can descale my microwave stereliser.

You need citric acid - you can buy it at most chemists for about 60p.

Mix 10g of citric acid with 200ml water and pour into unit. Heat on full for 2 minutes with the lid off, leave for 30 minutes then drain and rinse. Run a full cycle with the usual amount of water (but without any bottles or anything in the unit) and you're all set again.
