Noticing a scale build-up on the soleplate over time is very normal, and there’s nothing to worry about it. Following a correct cleaning process can help you get rid of the build-up in no time. Use white vinegar: Mix equal parts of distilled white vinegar and distilled water. Take a wet lint-free cloth and pour some solution on it. Wipe the soleplate: Use the cloth to wipe the soleplate in circular motions. Fill the tank with the solution: Pour the same solution into the water tank until it is a third full. Turn on: Now, turn on the iron to medium heat. Steam: Let the iron steam for about 10-15 minutes by pressing the steam button repeatedly. (If your iron has a self-clean button you can use it) Refill: Once done, refill the chamber with clean water. Steam: Turn on the iron and let it steam again. This thorough cleaning process will help you descale your iron and freshen it up.
