Throw it in the sewers and forget about the blockages in the pipes.

Instructions:
Cut 1/2 lemon and remove the seeds.
In a container, place the lemons and cover them with a little water.
Add 2 tablespoons of salt. Table salt has a good bactericidal and disinfecting effect.
Mix it very well.
Filter the mixture with a strainer.
Add 1 drop of dishwashing detergent and mix again.
Pour the mixture into ice-cooked mussels and freeze.
To use it, place a cube in the drain.
Fill a bucket with hot water and place it in the sink.
Pour hot water into the sewers.
Perform this process twice a week to dissolve blockages and remove food and fat residues.
