Get rid of lime deposits in a tea kettle by adding 1/2 cup white distilled vinegar to the water and letting it sit overnight.
If more drastic action is needed, boil full-strength white vinegar in the kettle a few minutes, let cool, and re-use the tea kettle with plain water. Don't pour the tea kettle vinegar down the drain.
You can freshen the drain if you first pour about 1/2 cup baking soda down the drain, then pour the hot vinegar down the drain. Or, you could use the vinegar to kill weeds. Make it do double duty!

To remove the buildup from the inside of a tea kettle, a friend told me this method.
Fill the tea kettle with lemon juice (bottle from juice section in grocery store is OK). Put in enough juice to cover the buildup. Leave it alone for some six hours, twirling the pot occasionally to swirl the juice.
Empty and wash clean.

RE: Removing Build Up from Tea Kettle
Vinegar is a frugal natural room freshener (once the smell dissipates) and it removes mineral deposits. I fill my kettle or coffee pot with vinegar, heat it, then turn it off to sit for 2 hours. Dispose of vinegar, it freshens your drains, then run clear water through your nice clean pot.

Pour vinegar in it and let it sit for a few hours. You could heat the kettle as well, to speed up the chemical reaction. There are also stronger descalers for sale in the hardware store or grocery store, or you could use CLR. Descale it whenever there appears to be significant build-up. Kettles take longer to boil when there is a lot of scale. (12/22/2009)
I'd use vinegar to clean it now. To prevent having buildup again, get a furr collector. It is a little thing of wound up wire and it will go through the opening in the tea kettle. I got mine in London (while on a great trip) years ago and I still use it. (12/22/2009)
