This popular “grandma’s trick” has taken the internet by storm, promising a clean toilet in just 2 minutes – with absolutely no effort. While the method is effective, don’t overestimate the time it takes: Preparation and application itself only take 2 minutes, but the actual effect only kicks in after a while.
The secret lies in the combination of baking soda and vinegar (or citric acid). These two ingredients together create a powerful chemical reaction that literally dissolves limescale and grime from the surface.
How to effectively clean your toilet without scrubbing:
🛠 What you need:
1 cup baking soda (approx. 150–200 g)
1 to 2 cups white wine vinegar (or citric acid dissolved in hot water for a stronger effect)
⏱ Application (Quick 2-minute application):
Sprinkle (0.5 minutes): Pour one cup of baking soda into the toilet bowl and sprinkle it evenly. Pay particular attention to the areas directly under the rim where the water runs off and most limescale deposits form.
Pour and activate (0.5 minutes): Slowly pour the vinegar directly onto the baking soda. The mixture will immediately foam up vigorously. This releases carbon dioxide, which mechanically loosens the deposits.
Spread (1 minute): Use a toilet brush to evenly distribute the resulting foam throughout the entire bowl. ⏳ And now the most important (waiting) phase:
Even though you’ll often find advice online that says 2 minutes is sufficient, for optimal results you should let the mixture work for at least 15 to 30 minutes (ideally overnight if the toilet is severely clogged). The acid needs time to dissolve the limescale.
After this time, simply give the toilet bowl a light brush and flush. The result: a sparkling clean and odor-free toilet.
💡 Grandma’s tip for particularly stubborn clogs:
If you have old, brownish limescale deposits at the bottom of the toilet that baking soda and vinegar can’t remove, Grandma had another trick up her sleeve: citric acid and hot water.
Empty the toilet as much as possible (e.g., with a plastic cup). Pour the entire contents of the citric acid packet (approx. 100 g) into the toilet bowl. Pour hot (but not boiling!) water into a kettle to prevent the ceramic from cracking.
