The stuff previously referred to is citric acid - buy it from your local pharmacy to be sure it's culinary (food) grade - very cheap - we use it for our babies bottle steriliser. personally, would put all the cups into a bowl or sink, evenly spread a couple of tablespoons between each cup, boil a kettle & fill each cup to the brim & leave at least 30 mins, then empty, wash & sterilse with boiled water again xx

all sounds good but involve a trip to buy something special, I always use simple Washing powder as one other camper has suggested but it works best with boiling water.
As spoonful of powder is enough in a cup, fill with boiling water and leave until cool.
I tried bleach - even neat! - on mine and it didn't work, so used Steradent tablets and they came up a treat. If you've already got Steradent tablets then you've nothing to lose by trying them first.
