This is getting quicker! I hadn't thought of putting them in oven. I've ordered the citric acid so will try that when it comes, first try was water only with drop of washing up liquid and that gave a good result.
Ordered citric acid, why? All you had to do is ask your lass to pop in to wilkinsons and get a box (naturally you said it was for descaling the kettle) think its only £1.50 a box
