Cleaning inside of your kettle

Looking at the inside of my kettle and oh boy, its needs a clean.  So to the internet i go.

Here are some suggestions:

  1. Fill kettle with cold water pour in baking soda about half a cup. Allow to come to a boil then turn off and let hot water mixture do the work maybe about an hour. Pour out and rinse thoroughly with hot water. Does a great job.
  2. White vinegar works best. Mix it 50/50 water and vinegar, bring it to a boil, shut it off and let it soak for 15 minutes or so. Yes, you will have to rinse it several times to get the vinegar smell out. If the 50/50 mix doesn’t work, try it again full strength.
  3. boil one part vinegar three parts water and let it sit for a while ( I go off and do other things so it probably sits at least a half hour for me) I am sure fifteen minutes is fine. I pour it out and then I put lemon juice (one part lemon 2 parts water) boil it again and empty. The smell is fine and it is super clean.
  4. Cut a lemon or lime into 4 pieces. Fill the kettle with water up to the maximum level, squeeze and put the lemon slices inside, and boil the water. Let the water cool down for 1 hour and boil the water again. The kettle will be as clean as new.
  5. The best way for me is fill the kettle, pour some tartaric acid and boil. Once boiled, empty kettle, fill up with cold water, and boil again.  Clean as a whistle!

So, if you have any ideas, please let me know!!
