It often happens that an unfinished lunch or dinner ends up going straight into the toilet.
However, there are a number of products that should never end up in the sewer.
Unfinished coffee can cause pipes to become clogged and wear out quickly, especially if they are made of cast iron.
Instead of mercilessly saying goodbye to leftover coffee, give it a second life, for example, in the form of a skin scrub.
The fat left in the frying pan after it is flushed down the toilet settles on the walls of the pipes.
Over time, it accumulates and causes a blockage.
Although hot water can hardly be called a product, it nevertheless deserves a place on this list.
If you need to get rid of boiling water, you should first wait until it cools down before pouring it down the drain. If you pour boiling liquid on the enamel first and then cold water, it will be irreparably damaged.
