How to clean a flat iron and remove buildup

Why plates get dirty

Most styling products are designed to coat the hair. When a coated section passes between hot plates, some of that coating transfers to the plates and bakes on. Silicone heavy serums, strong hold hairspray applied before ironing, and dry shampoo are common sources. You may see a cloudy film, brown spots near the edges or a sticky feel when the plates are cool.

Buildup can make the plates grab instead of glide, and it can be one reason your hair smells burnt while you style. Cleaning does not change how the iron heats, but it keeps the plate surface smooth.

What you need

• Soft microfiber or cotton cloth
• Water
• Rubbing alcohol (isopropyl) for sticky residue, if your manual allows it
• Cotton swabs for edges and the hinge area
• A dry towel to work on

Note.Always unplug the iron and let it cool fully before cleaning. Do not put the iron in water or run it under a tap. Check the manual, since some makers give their own cleaning instructions.

Step by step: routine cleaning

1. 1

   Unplug the iron and leave it until the plates are cool to the touch.

2. 2

   Dampen a soft cloth with water. Wring it out so it is barely damp, not wet.

3. 3

   Wipe each plate from the hinge to the tip, using light pressure.

4. 4

   Wipe the outer housing and the plate edges, where residue collects.

5. 5

   Use a cotton swab around the floating plate mounts and along the gaps. Do not force anything into the gaps.

6. 6

   Dry the plates and housing with a clean, dry cloth.

7. 7

   Let the iron air for a few minutes before plugging it back in.

Removing stubborn buildup

If water does not lift the residue, many people use a small amount of rubbing alcohol on a cloth or swab. Rub gently in small circles on the spot, then wipe with a water dampened cloth and dry. Repeat rather than scrubbing harder. Make sure the alcohol has fully evaporated before you plug the iron in, since it is flammable.

Some people loosen buildup by warming the iron briefly, unplugging it, and wiping once it is only slightly warm. Only do this if your manual allows it, and never touch a hot plate. The safest default is to clean when cool.

Ceramic vs titanium plates

Ceramic plates and ceramic coated plates have a smooth finish that can scratch or chip if you scrub with something abrasive. Titanium plates are generally harder, but they still should not be scratched or scraped. Either way, a soft cloth and patience work best. Our ceramic vs titanium flat iron page explains how the materials differ in use.

If a coating is visibly chipped or peeling, stop using the iron and contact the maker. Damaged plates can snag hair, and the issue may be covered under the warranty; see hair tool warranties.

How often to clean and how to keep plates clean

A quick wipe once a week suits most people who style a few times a week. Clean more often if you use lots of product or see residue. A few habits reduce buildup:

• Apply heat protectant, let it dry, then iron. Do not iron through wet product.
• Use hairspray after ironing, not before.
• Iron clean hair when you can. Day three hair with dry shampoo carries more residue.
• Store the iron with its plate guard once cool.

Frequently asked questions

Can I clean a flat iron with rubbing alcohol? Many people do, using a small amount on a cloth when the iron is cool and unplugged. Let it evaporate fully before heating the iron, and check your manual first.

How do I clean a ghd or other floating plate iron? The same way: cool and unplugged, a damp soft cloth on the plates and housing, and a swab around the plate edges. Do not pry at floating plates.

Why does my flat iron leave residue on my hair? Usually product buildup on the plates. Clean them and iron through hair with less product on it.

Is it safe to clean a hot flat iron? No. Unplug it and let it cool. Wiping hot plates risks burns and can damage the plate surface.
