Hello,

We live in a very hard water area and the kettle scales up very very
quickly, I have always used de scaler tablets or powder to de scale
the kettle however I was wondering if there was another way of doing
it as the price of de scaler is working out to be quite expensive.

I have Googled it and most people suggest vinegar, bicarbonate of soda
or lemon juice, somehow I don't have any faith in those things.

Citric acid was 69p for 150 gms last time I looked. A tablespoon should
be plenty
