How you can remove boiler scale?

To remove boiler scale, you can use descaling agents such as citric acid, vinegar, or commercial descalers specifically designed for boilers. Begin by shutting down the boiler and allowing it to cool, then drain the water. Apply the descaling solution according to the manufacturer's instructions, allowing it to sit for the recommended time before flushing the system thoroughly with clean water to remove any remaining scale and residue. Regular maintenance and periodic descaling can help prevent future buildup.
