Using Soda Crystals, Baking Soda, or White Vinegar:

Remove Water from Bowl: First, use your toilet brush like a plunger to push out as much water as possible from the bowl.

Apply Cleaning Agent: Pour about 1/4 liter of either soda crystals, baking soda, or white vinegar directly into the toilet bowl. For the best results, let it sit overnight.

Scrub Vigorously: The next day, scrub the bottom of the bowl thoroughly with the brush to remove all deposits. If necessary, repeat the process with a larger quantity (1/2 liter) of your chosen cleaning agent for tougher stains.

Flush Away Residue: After scrubbing, flush the toilet to rinse away any remaining deposits.

Extra Tip for Enhanced Cleaning:

For greater effectiveness, press paper towels soaked in white vinegar against the interior walls of the toilet bowl. This can help in removing stains from the sides of the bowl.

Combining Methods for Better Results:

Use white vinegar on the bowl’s walls and soda crystals for the bottom. This combination can significantly boost the effectiveness of your cleaning efforts.

By following these simple yet effective tips, you can keep your toilet bowl clean, hygienic, and sparkling without resorting to harsh chemicals. These eco-friendly solutions are not only good for the environment but also gentle on your plumbing.
