Tips and Lifehacks Every Housewife Should be Aware of

Written by Olivia Paxton. Updated on Can You Iron Polyester

Polyester is a very common and convenient fabric that is widely used today. Despite all the benefits of using it, there is one huge disadvantage. Yes, if now you are thinking about the wrinkles then you are right!

To learn how to get wrinkles out of polyester and keep your apparel neat and tidy, this article will be a great help for you.

Can You Iron Polyester?

Shortly speaking, yes, you can iron this fabric. However, if you need to do this, remember to follow simple ironing recommendations so that your polyester item remains good-looking and of decent quality.

First of all, all polyester clothes must be ironed using low temperature settings only (around 300F or even lower)! Since the material is actually thermoplastic, it will simply melt if you put a hot iron on it! And anyway, this fabric is wrinkle-resistant so the worst that can happen is that you have it slightly creased, and for that, you don’t need a super hot iron.

The second nuance you need to keep in mind when ironing polyester is that this fabric must be ironed only when turned inside out. In addition, always make use of a damp iron cloth placed over the piece of clothing you are about to iron. Like that, the garment will remain safe.

Is Polyester Iron Safe?

Generally speaking, yes, polyester can be called iron safe but only if we follow the basic ironing instructions and rules! Fortunately, they are not difficult to memorize at all.

  1. You must use low heat settings only
  2. Use dampened pressing cloth for ironing
  3. Don’t leave your iron in the same spot since the fabric will melt
  4. Dampen your polyester item slightly before ironing
  5. Test the iron temperature before using it

If all these rules are followed precisely, your polyester garment will be safe and sound.

Why Can’t You Iron Polyester?

Well, it’s not actually that you can’t iron it. It is more that you can’t do this under certain conditions. See, due to the specifics of its manufacturing, this fabric can’t stand heat so using a hot iron is prohibited. This is why a myth appeared that polyester can’t be ironed at all. And perhaps because polyester is basically wrinkle-resistant, too.

But since the material does tend to crease a bit, it still needs some light ironing now and then. Only ensure you are using a low-heat iron setting and a damp pressing cloth, and there will be nothing to worry about.

What Setting To Iron Polyester?

To keep your garment in a proper condition, double-check the iron settings each time before you start ironing polyester.

  • The temperature must be around 300F or lower (use cool to warm regime)
  • Start ironing on the lowest temperature setting and if needed, rise it a bit

And always remember to test the iron on the corner or a reverse side of the apparel first! Like this, you will see whether the level of heat is OK or not.

What Temperature To Iron Polyester?

Different irons have different scales displaying the temperature settings. But no iron shows it in degrees unfortunately. So to be absolutely sure that you are using the correct heat regime, opt for a one-dot setting (if your iron use dots to indicate temperature).

You can raise it up to two dots, but only if you see that the colder setting doesn’t work well, and only after you test the iron on the corner of your apparel.

How To Iron Polyester Dress?

How to Iron Polyester Without Causing Damage to It

Quite a lot of synthetic fabrics have the same irritating drawback that turns modest housewives crazy every time they have to deal with it. It’s those nasty wrinkles! 

Once you ironed your dress or a blouse, it looks so nice and charming, but just give it a try and sit on a bench or lean onto something, and you will see the slattern gathers on your garment.

Does polyester wrinkle? No matter what people may say, polyester can get wrinkled, however, not so much as some of the natural fabrics like linen, for example.

Its tendency for wrinkling depends on whether it is a 100% pure polyester or a mix of this fabric with some other fibers. And of course, the methods used for making the fabric matter.

Is ironing polyester allowed, you may ask? Indeed, synthetic fabrics are far more sensitive when it comes to ironing and they require a more careful attitude and more attention.

Some say that ironing polyester is strictly forbidden but in fact, when being done correctly following the safety instructions, it is absolutely harmless to your synthetic apparel.

Ironing Polyester

So how to iron polyester dress or any other garment without turning it into a mess?

  • If you noticed any gatherings on the polyester item after washing and drying it, turn the apparel inside out first.
  • Lay it on the ironing board and ensure it is spread evenly without any extra gatherings. Be especially meticulous with the wrinkled areas!
  • Take a cloth, dampen it and cover the garment with it.
  • Iron on the damp cover directly avoiding touching the fabric itself as it can melt under the influence of the heat of an iron.
  • As a variant, you could take a dry cloth, spread it over the garment and spray with water over the shrunken zones.

If you don’t have a special cover for ironing to get wrinkles out of polyester, feel free to use any clean cotton towel, napkin or even a handkerchief.

Remember to hang the garment on the hanger the second you are finished with ironing it to prevent any new wrinkles from appearing!

Have you ever thought that it is in fact possible to unwrinkle the polyester apparel without even ironing it? But it is true! And here is how you can do it.

Use your shower

Can’t get wrinkles out of polyester? Your shower may help! Yes, simply it. 

Take the synthetic apparel to the bathroom, close all the windows (if there are any) and the door to keep the warmth and moisture inside, and hang the garment on the shower rod. After 10 or 15 minutes, the fabric will start de-wrinkling or, depending on how badly wrinkled it was before, it will be ready to be put on.

Dryer de-wrinkler

A tumble-dryer is another option. To use it, mix together one part of any fabric softener good for synthetics and three parts water, pulverize it over the gatherings, put the apparel into the barrel together with a damp towel and start the dryer for ten minutes.

If the crinkles are not gone, repeat the cycle again.

As a variant, try to simply pulverize the unwrinkling mixture over the garment and hang it up to dry.

Getting wrinkles out of polyester using a hairdryer

Probably the fastest way to get rid of the crinkles is to turn on the hairdryer, direct the airflow to the areas that need to be treated and see how they are vanishing.

Damp towels method

To destroy the corrugations, lay the apparel on the flat and firm surface like a tabletop, take a damp towel and, pressing it carefully, treat the shrunken areas with it.

Hang your item to dry and straighten itself.

Vinegar solution for unwrinkling

To remove wrinkles from polyester, prepare a vinegar and water solution using one part vinegar and three parts water. Pulverize it over the corrugations and hang the apparel to dry.

All of these methods are easy to do and none of them requires any special or expensive means and products to treat the wrinkles. To choose the best one that fits your polyester garment, try them all to see how each of them works on a particular item.
