Pour Coca Cola into your kettle and leave all day. This will remove limescale and leaves it clean inside.

my grandad used to clean the bathroom this way.

and because it worked he forbid my mum and my aunt to drink coke at home - for about 10 years. XD

If you go to Snopes.com and do a site search for Coca-Cola, you'll come up with about 70 pages of entries. I also saw an episode of Mythbusters in which they tested various legendary uses for Coke; most of them didn't work.

Good for putting out fires

Mixed with Rum it makes a dandy drink too.

Yup, but pepsi is a crisper refresher.

Jeepers, if it can clean toilets, imagine what it does to one's inards!

Your innards are also highly acidic. Besides it is often a good idea to clean the pipes. LOL.

if you step on a sea urchin, fill a plastic bag with coca-cola, tie it around your foot and leave for 15 mins. the acid dissolves the spikes, painlessly and efficiently.
