What is the overflow on the washbasin?

The overflow is the small hole on the rear wall of the washbasin. The cavity behind the washbasin is also part of the overflow. This outlet is designed to drain away excess water and stop the bathroom flooding if you leave the tap unattended or forget to turn off the water.  

How to clean your washbasin

Household remedies are often ideal for cleaning the outlet in the washbasin. We tell you which ones work particularly well and how to tackle stubborn blockages. 

Clean the overflow with shaving foam

Shaving foam is a simple solution to clean the washbasin outlet. To clean your washbasin overflow with shaving foam, proceed as follows: spray plenty of shaving foam directly into the outlet and leave it to work for a few minutes. Then rinse the foam off with water. We recommend rinsing the water directly into the overflow. Finally, use a toothbrush to remove any visible dirt from the outside. 

Baking powder to clear blockages in the washbasin overflow

Another household remedy you can use to clean the washbasin overflow is everyday baking powder. All you need is baking powder, vinegar, a funnel and a bottle brush or toothbrush. Use the funnel to pour two tablespoons of baking powder into the overflow and then add a small cup of vinegar. Leave the mixture to work for 10 to 20 minutes and then clean the surfaces with the brush. Rinse with lots of cold water to remove any residue. 

Bicarbonate of soda & vinegar to clean washbasin overflow

As well as baking powder, you can also use bicarbonate of soda to clean the overflow. Follow the steps described above but simply replace the baking powder with bicarbonate of soda. If you want to use vinegar to clean the overflow but without bicarbonate of soda, use an old, lint-free cloth. Soak it in vinegar and push it deep inside the overflow outlet. You should, of course, be able to pull it back out again. Leave the vinegar to work for an hour, then remove the cloth and rinse with water. Make sure you ventilate the room well!

Prevent problems by keeping the overflow outlet clean

The easiest way to prevent soiling and blockages is to make the washbasin overflow part of your regular cleaning routine. Simple household remedies can be used for cleaning. Another tip is never to dispose of foreign objects in the washbasin overflow. For example, fingernails, hair, cotton buds and more.
