Big toilet problem

Hello, to all of you. Who can help me? I need a product with which I can get rid of stubborn lime scale in the toilet. The following product is already excluded (did not work): WC-Tabs (from DM-Drogerie Markt) - with 3-phase power I am grateful for any idea! Best regards

Where is the limescale located? If under the rim, soak an old dish towel well with vinegar essence, stuff it into the rim and let it work overnight. Remove and rinse in the morning, repeat if necessary.

1-2 liters of water in the kettle with 2-3 tablespoons of [Amidosulfonsäure] boil and pour into the toilet. Afterwards, the kettle is also descaled.

Grandma's home remedy is citric acid, right? Just buy a kilo and press it into the toilet. No, but I think Neige is right about the vinegar... I found instructions:

Simply pour half to a whole bottle of vinegar essence (about 2 euros in the supermarket), depending on the degree of dirtiness, into a pot and heat it strongly.

Carefully pour the hot stuff into the toilet bowl. The limescale will literally be dissolved. For difficult spots, just soak a cloth with it and let it work.

Did the tips help you?

Buy citric acid at the drugstore. It will then cost you 2€ and last for 1-2 years.
