Removing limescale from PVC pipes is an important step to keep pipes clear and extend their lifespan. Here are a few tips for removing limescale from PVC pipes:
1.Use vinegar water: Mix vinegar and water in a 1:1 ratio and pour the mixture into the affected PVC pipe. Allow the mixture to sit in the tubing for a while, preferably for at least a few hours or overnight. Vinegar has an acidic, good ability to dissolve limescale and can help remove limescale from inside pipes. After that, rinse the pipe with clean water to wash away the remaining vinegar and limescale.
2.Use citric acid: Citric acid is also a common natural substance for removing limescale. Mix the citric acid powder into clean water to make a solution. Pour the solution into the affected tubing and let it soak for some time. Then rinse the pipes with clean water to wash away the citric acid and limescale residue.
3.Use an alkaline cleaner: If limescale is severe and not easy to remove, consider using an alkaline cleaner. When choosing a cleaner, make sure it is safe to use on PVC materials. Pour it into the pipe as directed by the cleaner and let it act inside the pipe for a while. Rinse the tubing thoroughly with clean water to ensure that the residue is removed.
4.Mechanical cleaning: Mechanical cleaning may be required for stubborn limescale that is difficult to remove. Physical wiping and removal can be done using tools such as wire brushes or pipe cleaners. But please note that care should be taken when using mechanical cleaning to avoid damaging the PVC pipe surface.
It is important to note that different types and degrees of limescale may require different removal methods, and before using any cleaner or tool, confirm its suitability for PVC materials. Also, be sure to wear gloves and eye protection to ensure your safety when performing the cleaning process. If the situation is serious or unsure how to remove it, it is recommended to consult a professional plumbing repairer or scale removal service provider.
