Unclogging a drain naturally: baking soda, vinegar and other methods
A sink that drains slowly or a shower that forms a puddle: before bringing out the harsh chemicals, there are natural methods, effective and safe for your pipes and the environment.
The baking soda + vinegar method
This is the best known and most effective method for light to moderate clogs. The baking soda (base) reacts with the vinegar (acid) producing foam that loosens grease and residue.
- Pour 100 g of baking soda into the drain
- Add 100 cl of white vinegar (first in small amounts to control the foam)
- Let it work for 30 minutes (the foam does the work)
- Pour a pot of boiling water to rinse
The plunger, the mechanical weapon
For a more stubborn clog, the plunger is very effective:
- Fill the basin with water until the plunger is covered
- Position the plunger over the drain
- Pump vigorously and regularly
- Repeat until the water flows freely
The other natural methods
Salt and hot water
Pour half a cup of coarse salt followed by very hot water. The abrasive salt loosens deposits and the hot water dissolves them. Effective on grease.
The plumbing snake
For deep clogs (hair in the bathroom in particular), the snake is inserted into the pipe and physically removes the clog. Available in a manual version (a few euros) or electric for large clogs.
Dismantling the trap
Last resort before the plumber: unscrew the P-trap (the bend under the sink), empty it into a bucket and clean it. Most clogs are found there. Simple, free and definitive.
How to prevent clogs?
- Install a filter or strainer on every drain
- Never pour fats or oils down the sink
- Brush your hair regularly before washing
- Run hot water after every kitchen use
- Monthly baking soda + vinegar maintenance
When to call a professional?
If the water no longer drains at all despite the plunger and snake, or if several sinks are clogged at the same time, the problem may be deeper (main sewer line or network). In that case, call a plumber: forcing further could damage your pipes.
