Have you noticed that your gas stove isn’t heating as well as it used to? Is the flame weaker, irregular, or even reddish? This problem, while common, can significantly impact your cooking. Meat that cooks slowly instead of searing, water that takes forever to boil… The cause? Injectors that have become clogged over time with food residue and grease. Fortunately, there’s a simple and effective solution to restore their full performance.
Why do your stove’s injectors get clogged?

Even if you clean your cooktop regularly, the burners are still exposed to food splashes, liquids, and grease. Over time, these residues build up and reduce gas flow. The result: The flame becomes unstable, noisy, and loses intensity. A perfect flame should be blue, even, and steady. If it flickers or turns yellow-orange, that’s a sign that it’s time for intervention.
You don’t need to replace your burners! A thorough cleaning is all it takes to restore their full performance. Follow these steps:
- Prepare your stove
- Turn off the stove completely and let it cool down.
- Remove all removable parts: grates, burners and flame diffusers.
- For safety reasons, turn off the gas supply.
- Clean the surface and the burners
- Wipe with a dry cloth or soft brush to remove crumbs and dirt.
- Use a scraper or a sponge soaked in soapy water to remove encrusted grease.
- Dry everything thoroughly before proceeding to the next step.
- Clear and clean injectors
- Carefully unscrew each injector counterclockwise using a suitable wrench.
- Soak them in a mixture of hot water and white vinegar for several hours to dissolve the grease.
- Use a fine needle or toothpick to remove any residue stuck in the small holes.
- Rinse them thoroughly and dry them completely before screwing them back on.
