I descale my kettle with citric acid. Then I pour that hot water into the toilet and close the lid. Come back 10 minutes later, flush and brush it with the toilet brush at the same time as the water falls. Don’t even need to put effort on the brushing.

Haven’t had issues in two years.

Assassin’s Creed Odyssey. I am a big classic mythology nerd, but I got Valhalla as a present and I want to finish it first, yet life keeps getting in the way.
