Before attempting the vinegar treatment, I took a good look inside my toilet tank. Unsurprisingly, it was not a pretty sight. The walls of the tank were lined with a thick, crusty layer of limescale and rust. The once-white surfaces had turned a murky brown and orange, with some areas feeling gritty to
the touch. The buildup was particularly thick around the water line and the mechanisms inside the tank, including the flapper and the fill valve. It was clear that fifteen years of mineral-rich water had left its mark.
3. How I Measured, Poured, And Left The Vinegar Overnight
To start the process, I first turned off the water supply to the toilet and flushed it to empty the tank as much as possible. This would allow the vinegar to have maximum contact with the surfaces inside the tank. I then carefully measured out a gallon of white vinegar, which I had purchased specifically for this purpose. Pouring it slowly into the tank, I ensured that it covered the entire surface area, especially the parts with the most buildup.
