Start by using a plunger to remove as much water as possible from the toilet bowl. The drier the bowl, the better the vinegar can work its magic.
Step 2: Apply the Vinegar

Pour some distilled vinegar directly into the toilet bowl. Then, take a few paper towels and soak them in vinegar. Place the vinegar-soaked paper towels around the rim of the toilet bowl, ensuring they stick and stay in place.

Step 3: Let It Sit
Allow the vinegar and paper towels to sit overnight. This will give the vinegar enough time to break down the hard water stains.
Step 4: Scrub and Flush
In the morning, remove the paper towels and grab a toilet brush. Scrub the toilet bowl thoroughly, paying extra attention to the areas with hard water stains. Once you’re done scrubbing, flush the toilet to remove any remaining vinegar and stains.
If you find that there are still lingering hard water stains, you may need to repeat the process.
And that’s it! With this simple and natural cleaning hack, you can say goodbye to those pesky hard water stains in your toilet bowl. For a visual demonstration of this method, check out the video below!
