Cola Cleaner

Our toilet has been looking a little the worse for wear recently with a stubborn build-up of limescale. I'd tried various limescale removers but none worked very well and all smelt vile. Then I read somewhere that cheap cola would do the trick. So I bought the cheapest bottle I could find (40 cents for 2 litres) and not expecting too much success poured it down the toilet and left it over night. "Mum - some-one's done a brown wee," came Ben's dulcet tones at some unearthly hour this morning. It was far too early to try and explain but when I did get up a while later I have to say I was a bit shocked. The limescale was now dark brown and looked a whole lot worse. HOWEVER, a quick scrub round with the loo brush and it came up as good as new. Fantastic - clean loo with no horrible limescale remover smells. Simon had also poured a little of the cola into a lovely blue glass bottle I want to use for oil but could not get the alcohol smell out of. Guess what - one night of cola, a quick rinse in the morning and it too is like new. All I can say is, if that is what cola does to limescale and alcohol smells what the heck does it do to stomachs?
