It doesn't matter if it's a bottle, a decanter or a vase - cleaning the "insides" of narrow-necked containers is truly a challenge.
This is probably what all housewives think, except for those who are familiar with the old life hack that allows you to keep any dishes clean.
If you are still among the first who do not know, read this article as soon as possible to learn a simple trick that will help you out in such a situation.
It turns out that in order to make containers shine (in the literal sense of the word), you will need the simplest soda.
And not a pack, as it might seem at first glance, but only 1-2 teaspoons.
Pour the specified amount into the container to be cleaned and fill it to the top with water.
Now set the container aside for a few hours. Then shake it upside down.
Using this method, you can easily remove dirt from a bottle or any other container with a narrow neck.
