We’ve all been there.

You wake up in the morning and decide to make a nice cup of tea or coffee before you go off to work.

After heating your water in the kettle, you pour it into your mug and take a sip…. but ugh! It tastes metallic. What gives?

If you can relate, then this article is for you.

I’ll be teaching you how to clean and descale your electric kettle by using baking soda.

Let’s begin.

What you’ll need:

Any shallow container

Step 3. Dip the brush in the baking soda paste and start brushing the inside of the kettle. If the opening of the kettle is narrow and you’re having a hard time getting the right angle with the brush, use a scrub sponge. Focus on removing the limescale and stains.

Step 5. Put 1 tablespoon of baking soda for every liter of water inside the kettle and boil. Then, let it sit for 20-30 minutes. This should remove any remaining limescale.

5 Electric Kettle Maintenance Tips 

  1. Avoid using highly abrasive products when cleaning parts made from stainless steel. They can leave scratches.
  2. Dry the outside of your electric kettle after each use.
  3. Deep clean the electric kettle before any weird taste and odors set in. Clean it at least once every 3 to 4 weeks.
  4. For the outside of your kettle, just use some water mixed with a few drops of dish soap and give it a good wash. Rinse it with water afterward. Dry it, and you’re good to go. 
  5. Never let the water reach the heating element and electrical parts of the kettle. 


Electric kettles are one of the most neglected appliances in our daily lives. If you clean it regularly and descale it with baking soda, you can get many more years out of it.
