Stubborn toilet limescale disappears with this ingredient

Mix with baking soda: Create a paste of baking soda and vinegar and apply it to the limescale. Let it fizz for a few minutes before scrubbing.
Add essential oils: Add a few drops of your favorite essential oil, such as tea tree oil or lemon oil, to the vinegar for a pleasant aroma.
Vinegar’s acidity effectively dissolves limescale, leaving your toilet bowl sparkling clean.

Remember to always wear gloves when cleaning with vinegar.

I hope this helps!
