Over time, irons can accumulate sticky residue from synthetic and natural fibers, which melt onto the soleplate when the temperature is too high. This buildup can snag fabrics, leave stains, and reduce your iron’s effectiveness. Keeping your iron clean not only ensures your clothes look their best but also helps your iron last longer.
How often to clean an iron
How often you clean your iron depends on how frequently you use it. If you iron regularly, aim to clean it about once a month. For occasional use, a few deep cleans per year—or whenever you notice visible buildup on the soleplate—should be enough to keep your iron performing well.
How to prevent buildup in the first place
Preventing residue from forming on your iron is easier than cleaning it later. Always start with low-temperature fabrics like nylon and silk, saving high-heat fabrics like cotton and linen for last.
If you use spray starch, let it fully soak into the fabric before ironing. And never leave water in the iron’s tank after using it, since stagnant water can seep through the steam holes, discolor the soleplate, and even corrode the internal parts.
How to clean an iron
Always follow the manufacturer’s instructions first, since soleplate materials can vary. While you may come across DIY suggestions, it’s not recommended to pour vinegar or any other cleaning product directly into your iron, as this can damage internal parts and coatings. Baking soda is a safer and highly effective option for all types of irons—just be sure to rinse it off thoroughly with a damp cloth to avoid clogging the steam holes.
What you'll need
- Baking soda
- Damp cloth or non-scratch scrubber
- Faultless Hot Iron Cleaner (optional for heavy buildup)
For light buildup
- Dampen a cloth or non-scratch scrubber.
- Dip it into baking soda and gently rub the soleplate to loosen grime.
- Wipe the soleplate (including the holes) with a damp cloth.
For heavy buildup
- Apply Good Housekeeping Seal holder Faultless Hot Iron Cleaner to a hot iron according to the package instructions to melt away stubborn, stuck-on messes.
- Flush the steam vents by holding the iron over a sink and pressing the steam burst button until the iron's reservoir is empty.
- Wipe with a clean cloth.
