Shrink Polyester Boiling Water


Have you ever accidentally shrunk your favorite polyester shirt or dress? Don’t worry, it happens to the best of us. But did you know that you can actually use boiling water to shrink polyester on purpose? This may sound counterintuitive, but it is a great hack to adjust the fit of your polyester clothing without having to buy a new one. In this article, we will guide you through the process of shrinking polyester using boiling water.

Things To Know

Before you start the process of shrinking your polyester clothing, there are a few things you should know to make sure that you achieve the desired result. Here are some important things to keep in mind:

  • Polyester fabrics have a melting point of around 180-200°C (356-392°F), which means that boiling water, which is at 100°C (212°F), will not melt or damage the fabric.
  • Polyester shrinks when exposed to heat, so boiling water is an effective way to shrink polyester clothing.
  • Different types of polyester fabrics may react differently to boiling water, so it is important to test a small area first before submerging the entire piece of clothing.


Now that you know the basics, here are some tips to ensure that you shrink your polyester clothing successfully:

  • Fill a pot with enough water to fully submerge the piece of clothing you want to shrink.
  • Bring the water to a boil and add the clothing to the pot.
  • Reduce the heat to a simmer and stir the clothing for about 5-10 minutes.
  • Remove the clothing from the pot and rinse it with cold water to stop the shrinking process.
  • Gently squeeze out the excess water and hang the clothing to dry.

Frequently Asked Questions
