Descale an Iron
Limescale blocks steam vents and leaves white marks on clothes. Flush it out with a simple white-vinegar solution.
Quick answer
Fill the water tank with equal parts white vinegar and water. Heat the iron to a medium-high setting and steam an old towel until the tank is empty. Rinse the tank with distilled water, then steam again to clear any vinegar smell.
Hard water leaves mineral deposits inside your iron. Over time these block the steam vents and spit white flakes onto fabric. A vinegar flush dissolves the buildup quickly.
What you’ll need
- white vinegar
- water
- old towel
- cotton cloth
- distilled water for refilling
Step by step
- 1
Mix the descaling solution
Pour equal parts white vinegar and tap water into a jug. Half a cup of each is usually enough. Stir briefly.
- 2
Fill the iron's reservoir
Always unplug the iron and let it cool completely before filling or emptying the water reservoir. Pour the vinegar mixture into the water tank up to the maximum fill line.
- 3
Heat and steam an old towel
Plug the iron in and set it to a medium-high temperature with steam on full. Iron an old towel or rag you do not mind staining. Press the steam button repeatedly. Continue until the reservoir is empty and brown or white scale comes out of the soleplate.
- 4
Rinse the reservoir
Unplug the iron and let it cool. Pour out any remaining liquid. Fill the tank with plain distilled water and shake it gently. Empty it completely through the steam vents by repeating the steaming process.
- 5
Steam with distilled water
Refill the tank with fresh distilled water. Heat the iron and steam the old towel again until the tank is nearly empty. This removes any lingering vinegar smell from the steam passages.
- 6
Wipe the soleplate
Once the iron is cool, dampen a cotton cloth with distilled water and wipe the soleplate. Check the steam holes for trapped flakes. Use a cotton bud to clear them if needed.
The iron soleplate and steam get very hot during this process. Place the iron on a stable ironing board and keep it away from children and pets. Never leave a hot iron face-down on fabric.
Common mistakes
- Using malt vinegar or balsamic vinegar, which can stain the reservoir
- Forgetting to rinse out the vinegar, leaving clothes smelling sour
- Steaming onto a good garment instead of a sacrificial towel
- Skipping the distilled-water final flush, which lets new scale form quickly
Frequently asked
Can I use commercial descaler instead of vinegar?
Yes, follow the manufacturer's instructions. Rinse thoroughly afterwards, as some descalers are stronger than vinegar.
How often should I descale my iron?
In hard-water areas, descale every month. In soft-water areas, every two to three months is usually enough.
Why is my iron still spitting after descaling?
Check that the temperature is high enough for the steam setting. Low heat can cause water droplets instead of steam. If the problem persists, repeat the flush.
