Sink unblocker

Old-fashioned plunger

Sometimes an old-fashioned plunger is enough to unclog a drain. Place it on the drain to unclog and move it up and down. The suction will loosen the dirt due to the force of the suction.

Soda

If this does not help you can take a handful of baking soda and dissolved it in 3 liters of boiling water and pour it down the drain.

Soda & Vinegar

A handful of soda and some vinegar directly into the drain and then rinsing it after a few minutes with hot water helps in more difficult cases.
