Caustic soda for stubborn blockages (use with caution)
Pour a liter of cold water and 3 cups of caustic soda into a plastic bucket.
Mix this solution with a wooden spoon until it starts to sizzle and get hot.
Pour it into the toilet and leave it to act for 30 or 60 minutes, depending on the level of incrustation.
Caustic soda does not foam, so it is easy to rinse and also allows you to thoroughly clean plumbing and sinks. Gloves and safety glasses are recommended when using this substance.
