When you strike a match, the sulfur it contains produces sulfur dioxide as it burns. This gas has the particularity of reacting with certain malodorous compounds (such as hydrogen sulfide) and temporarily neutralizing them .
In other words, this small, seemingly harmless fire “masks” the unpleasant gases present in certain pipes – particularly when the traps are empty or the seal is defective. The result? A rapid but temporary improvement in the ambient air.
But be careful, this is not a miracle solution. Neither sustainable nor risk-free.
Use with caution… or not at all
Even though this trick is old, it is not recommended for home use . Why? Because some gases like methane can be flammable. A simple match could therefore, in extreme cases, cause a small explosion or a fire.
That’s why professionals always assess the situation before lighting anything. At home, it’s better to opt for safer and equally effective solutions.
Natural tips to say goodbye to bad odors
Rather than pulling out your matchbox, here’s what you can safely do:
- Fill the drains regularly : A drain that is rarely used (such as a spare sink) can dry out. Pour a little water into it from time to time.
- Baking soda + white vinegar mix : Pour in about a tablespoon of baking soda , then a glass of white vinegar . Leave to act for a few minutes, then rinse with hot water.
- Ventilate the room : Even a simple half-open window can significantly improve air quality .
- Check the condition of the seals : A damaged or poorly installed seal can allow gases to escape. Inspect around toilets, sinks, and bathtubs.
Sometimes what looks like sleight of hand hides real logic.
