After 15 years of regular use, I finally decided to inspect the inside of my toilet tank. What I found was shocking. Thick layers of mineral deposits, limescale, rust, and brownish residue had built up on every surface. The tank looked neglected despite the outside of the toilet appearing clean. The flush had also grown weaker over time. Instead of harsh chemical cleaners, I chose a simple, natural solution: white vinegar, known for its acetic acid that dissolves buildup.

I turned off the water supply, flushed the toilet to empty the tank, and poured in a generous amount of white vinegar.
