Step-by-Step: Cleaning a Drain with Baking Soda and Vinegar
Before calling a professional, you can clear minor clogs yourself using this eco-friendly method. All you need is baking soda, household vinegar, a damp cloth, and boiling water.
1
Preparation
Remove coarse, visible dirt such as hair from the drain strainer. Have 3 to 4 tablespoons of baking soda and 100 to 150 ml of vinegar ready.
2
Pour in baking soda and vinegar
Pour the baking soda directly into the clogged drain. Then carefully pour the vinegar in after it. Caution: The mixture will immediately start to foam vigorously.
3
Let it work
Place a damp cloth over the drain to keep the foam inside the pipe. Let the mixture work for 10 to 15 minutes.
4
Rinse with hot water
Pour about a litre of boiling hot water down the drain. **Safety warning:** Keep your face at a safe distance, as the hot water can splash.
5
Check the result
Check if the water drains normally again. If this is not the case, the blockage is deeper and requires mechanical tools or a professional.
If this method is unsuccessful even after repeating it, you should contact a plumber to avoid damaging the pipe system.
Frequently Asked Questions About Clogged Drains
Here you will find answers to the most important questions about drain cleaning and the associated costs.
For a standard cleaning (approx. one hour of work including travel), you should expect costs between 200 and 350 CHF. For weekend emergencies, camera inspections, or complex thermal flushing, the costs are significantly higher.
In the shower and bathtub, hair and soap residue are usually the culprits. In the kitchen, grease and food scraps often lead to deposits that narrow the pipe's cross-section over time.
No. Chemical cleaners are often highly corrosive, pollute the environment, and if used incorrectly, can generate heat that deforms plastic pipes. Mechanical methods or home remedies are much safer.
An experienced plumber can clear most common clogs within the first hour of work (approx. 45 to 60 minutes).
The simplest and most effective measure is a hair strainer for a few francs. In addition, it helps to flush the drain once a week with boiling water to dissolve grease residues early on.
Do not hesitate to consult a professional for recurring problems to prevent major water damage to the pipes.
