Limescale is a problem in our area. Learning how to clean a kettle is the solution. We use water filters for our drinking water and limescale tablets in our washers to prevent damaging build up. One of the main places I notice the limescale is in the Kettle. Every day there is a slight white build up on the inside of the kettle that crystallizes into thick hard limescale chunks if not cleaned out properly.
When I first moved to Ireland I was constantly scrubbing my kettle and had the raw hands to prove it. After a bit a friend told me the secret to cleaning a kettle is vinegar, she recommended the Polish brand “Ocet” which can be found in the local Polish store for about 75¢. From that day forward I have never gone back to my old methods. Ocet works like a charm! Just pour about a cup of Ocet or regular white vinegar into the bottom of your kettle, let it sit for 5-10 minutes, then fill the kettle with water and boil. The results are amazing, no scrubbing required. I do this about every 1-2 weeks now and enjoy a clean kettle and tea without annoying white floaties.
