We have already mentioned that Polyester is wrinkle-resistant. Is it true? No, if you don’t take good care or wash polyester clothes regularly, they may have wrinkles in the long run.

Therefore, always wash or iron it properly. Sometimes, if you pack polyester clothes in the closet or bags with other fabrics, they may be damaged. So, be careful.

How to Remove Wrinkles From Polyester

Polyester is a synthetic that requires intense care. It can’t endure high temperatures. So, it would help to be more careful when removing wrinkles from such clothes. Luckily there are three ways to remove wrinkles out of Polyester. These three methods are-

  • Wash and dry properly.
  • Iron at low temperatures.
  • Steam out wrinkles.

Wash and dry properly

To remove wrinkles from Polyester, washing, and drying can be immensely important. Follow the instructions below to do it properly-

  1. Check Clothes Tag: Checking clothes tags can help you understand the exact wash cycle and water temperature for that dress. Such measurements may vary depending on the clothes type. Your dress may be 100% Polyester or a blend of Polyester and another softer fabric. So, check that tag first.
  2. Turn Cloth Inside Out: Although Polyester is durable and extremely strong, you should wash clothes inside out. It would protect clothes from the rough moment inside the machine. 
  3. Add Gentle Detergent and Fabric Softener: Choose a detergent that is free of harsh chemicals. Toxic and intense material can ruin the texture of Polyester. Therefore, using a soft one is always better. 
  4. Start Washing Machine and Remove After Cycle Ends: After starting the washing machine, wait a while for the process to finish. After finishing, transfer clothes as soon as possible. Otherwise, new wrinkles may develop.
  5. Don’t OverdryAlways use a clothes dryer for 15 to 20 minutes. While working, check the condition of your clothes after every 5 minutes. Use the permanent press cycle of your dryer. Otherwise, use a lower temperature for a perfect result. Remember, you can also hang your clothes on the roof to air dry. Air drying never hurts the fabric.
  6. Hang the Dress: When your clothes become dry, hang them on a hanger. Don’t put your dresses in the closet or drawer just after drying. Hang those for at least 5 minutes.

        Now, you can keep dresses in your wardrobe. Never forget to check those every month.

Many renowned companies are producing ironing boards in the market. You can easily buy a board for just $30.So, never worry about it.

  • Soleplate cleaning kit
  • Homemade soleplate cleaner

Homemade soleplate cleaner

  • Turn on the iron and set the temperature to a lower level. Allow it to heat up. The heated soleplate may soften Polyester marks.
  • Take a spoon and gently try to remove the spot. Never hurry. If so, you may ruin the surface. You may use tweezers for better finishing.
  • Unplug the iron and give it some time to cool down. Prepare a mix of baking soda and water by maintaining a ratio of 1:1.
  • Take a clean cloth and immerse it into the mixture. Now, use this cloth to clean the surface.
  • If you still observe any last residue of Polyester, don’t worry. Take a clean towel and soak it into the acetone-based nail polish remover. Use that towel on the surface.

Try until the stain is removed and you are satisfied with the final result.

Soleplate cleaning kit

Using a cleaning kit is tremendously easy. It’s hassle-free. Just follow the rules mentioned below-

  • Keep the water tank of iron empty.
  • Set the temperature to Cotton (3 dots) setting. Give it some time to heat up. Never use a cold iron.
  • Cover the ironing board with an old cloth.
  • Pick a cotton terry cloth and fold it into two. Apply two inches of cleaner on it and place it on the board.
  • Move your iron in a circular motion on the cloth with cleaner. Cover the whole soleplate area. You may notice some smoke. It’s normal.
  • Remove the iron and rub it on a second cloth to clean it properly.
  • You may use another cloth for better results. Remember, you can’t use dirty ones.
  • Now, your iron is ready to start. Check the soleplate before starting. Sometimes cleaner may block the steam holes.
  • After cleaning, turn on the iron and apply steaming on a piece of cloth. Check the performance before starting ironing clothes.

Using a soleplate cleaning kit is convenient for you. However, you need to understand that it can’t remove the permanent damage to the soleplate. It can only remove melted fabric from iron.

Frequently Asked Questions

Does polyester shrink in the washing machine or dryer?

Yes, polyester shrinks. Polyester is a robust and shrink-resistant fiber. If you don’t wash it properly, it may shrink down the road. Polyester can shrink in washing machine or dryer –

Can I heat-press polyester?

Yes, you can. If you love customizing your dress, you may want to heat press to your favorite polyester fabric too. Am I right?

First, the heat press works better on natural fabric, such as Cotton. As Polyester is synthetic, you may face some difficulty in this case. But, I am giving you a guideline-

  • Find the ideal temperature for your clothes. It may be somewhere between 270 to 300F.
  • Use the perfect transfer. Success depends on what type of transfer you use. If you choose a transfer that works better at high temperatures, never use it for Polyester. You may use it for another type of fabric.
  • Use a thin sheet to stop damaging the garment. Luckily, there are different types of thin sheets in the market. Choose a thinner one.
  • If you want to apply heat pressing on many clothes, select one or two pieces of clothes and give them a try. Remember, the process may not work if the temperature is too low.
  • Be gentle. If you hurry, you may fail. Patience is the key here.

If you follow these rules, you can successfully heat press on Polyester. However, sometimes it may leave scorch marks on the fabric. If so, wait for a few minutes until it cools down. Then, the damaged area may disappear. Otherwise, wash the dress properly.
