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. Linda (11/10/2005)
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)
I bought a second hand kettle from my charity shop, but never checked the inside. So, I need to really descale it. Can you use ordinary malt vinegar or cider vinegar, as all the tips say to use white vinegar? I just wondered what the difference is? Many thanks.
You could use malt or cider vinegar as well; sometimes they are more expensive here in North America, so that is why white is suggested. As I said in a previous post, you might look for a special kettle descaling product or CLR if you have that product in the UK. Either would be a stronger acid, which would speed up the process if there is a lot of scale. (05/24/2010)
I use borax. I put it in, add a little water to make a paste, let it sit for 30 minutes or so and scrub with a sponge. Rinse out well and several times. This is an all natural product so I would not suggest eating it, it is safe to use this way. (05/25/2010)
