How to Wash a Polyester Blanket

Polyester is a synthetic fabric that’s prized for its durability, resistance to moisture, and easy maintenance. While it’s typically more resistant to stains and wrinkles than natural fabrics, keeping a polyester blanket clean can ensure its longevity and keep it looking fresh. For those familiar with the fabric, how to wash a polyester blanket correctly without damage can still present a challenge.

Washing a polyester blanket requires care to maintain its quality. Use cold water, whether machine washing, hand washing, or spot cleaning. While machine washing on a gentle cycle is common, hand washing offers a controlled cleaning process. Dry on low heat or air-dry, and for specific stains, opt for spot cleaning. Check care labels before dry cleaning.

Here, we discuss the three methods to get your polyester blanket cleaned without causing wear or damage.

How to Machine Wash a Polyester Blanket

Machine washing is a widely used and efficient method to clean polyester blankets. It ensures thorough cleaning while maintaining the fabric’s integrity. Here are detailed steps to ensure the best results:

  1. Inspect the Blanket: Look over your polyester blanket to find any visible stains or spots.
  2. Pre-treat Stains: For any noticeable stains, apply a minimal amount of stain remover or liquid detergent directly to the affected area.
  3. Select the Gentle Cycle: This cycle is gentler on your polyester blanket and prevents potential damage or stretching.
  4. Use Cold Water: Cold water helps in preventing any potential shrinkage or damage to the fibers.
  5. Choose Mild Detergent: Harsh chemicals or bleach can harm the blanket’s fibers, so a mild detergent is best.
  6. Rinse Well: Ensure you rinse the polyester blanket thoroughly, making sure no detergent residue remains.
  7. Tumble Dry on Low or Air Dry: If using a dryer, opt for the lowest heat setting. If possible, consider air drying the polyester blanket to retain its shape and softness.

By following this method, you’ll ensure your polyester blanket remains clean, soft, and in prime condition for a long time.

How to Hand Wash a Polyester Blanket

Hand washing can be a gentle alternative for those who want to extend the lifespan of their polyester blankets. It allows for a more controlled cleaning process and can be especially effective for delicate or cherished blankets. Here’s how to go about it:

  1. Prepare the Cleaning Solution: Mix a mild detergent with cold water in a bathtub or a large basin until it forms a soapy solution.
  2. Submerge the Blanket: Lay the blanket in the water, ensuring it’s completely soaked.
  3. Agitate Gently: Use your hands to move the polyester blanket softly in the water, dislodging dirt without being rough on the fabric.
  4. Let it Soak: Leave the polyester blanket in the soapy solution for about 30 minutes to allow the detergent to break down any dirt or residues.
  5. Drain and Rinse: Empty the soapy water and refill with fresh, cold water. Move the blanket around to rinse out the detergent.
  6. Press Out Excess Water: Don’t wring the polyester blanket as it can distort its shape. Instead, press it gently to remove water.
  7. Air Dry Properly: Find a flat, clean surface to lay the blanket on, ideally outdoors in the shade. This prevents direct sunlight from potentially fading its color.

With hand washing, your polyester blanket receives personalized care, ensuring its cleanliness while preserving its quality and texture.

How to Spot Clean a Polyester Blanket

Spot cleaning is the go-to method for addressing minor spills or specific stains without the need for a full wash. It’s efficient, conserves water, and is quick. Here’s a step-by-step guide to effectively spot clean your polyester blanket:

  1. Identify the Affected Area: Before anything else, locate the stain or spill on the polyester blanket.
  2. Dampen a Clean Cloth: Wet a clean cloth with cold water. Wring out excess water so it’s damp, not dripping.
  3. Blot the Stain: Press the damp cloth onto the stain gently. The goal is to lift as much of the spill or stain as possible from the polyester blanket using only water.
  4. Apply a Gentle Cleaner: If water alone doesn’t do the trick, use a cloth with a minimal amount of mild detergent. Dab the stain softly.
  5. Blot with a Clean, Damp Cloth: After treating with detergent, use another damp cloth to blot and lift any soap residues.
  6. Air Out: Let the treated area dry naturally. Avoid direct sunlight to keep the polyester blanket’s color intact.
  7. Inspect: Once dry, check the area to ensure the stain is gone and there’s no soap residue.

Spot cleaning is an effective way to address unexpected messes, ensuring a spotlessly clean polyester blanket between full cleaning sessions.


What temperature should you use to wash a polyester blanket?

Using cold water is recommended when cleaning a polyester blanket. Warm or hot water can alter the fabric’s texture and may lead to unintended shrinkage, potentially changing the blanket’s softness and size.

Can you put a polyester blanket in the dryer?

Yes, polyester blankets can go in the dryer. Yet, to maintain the fabric’s quality and reduce potential wear over time, opt for the air-dry or a very low heat setting. Excessive heat can cause the polyester fibers to melt or warp.

How often should you wash a polyester blanket?

While a lot depends on personal use and preferences, washing a polyester blanket every 3-6 weeks is a general guideline. If the blanket is frequently used or exposed to dirt and contaminants, you might want to clean it more regularly.

How do you remove stains from a polyester blanket?

Spot cleaning is an excellent method for tackling specific stains. Begin by blotting with cold water. If that doesn’t lift the stain, apply a minimal amount of mild detergent on a cloth and gently dab the affected area. After treating, ensure you blot away any detergent with a clean, damp cloth and let the spot air dry.

Can you dry clean a polyester blanket?

Polyester blankets are suitable for dry cleaning. Before taking this route, it’s a good idea to check the care label on your blanket. Some polyester blends or finishes might have specific cleaning recommendations. Dry cleaning can be a beneficial option for intricate or heavy blankets that are challenging to wash at home.


Washing a polyester blanket doesn’t have to be a daunting task. With the right methods and care, you can ensure your blanket stays clean, fresh, and in great condition for years to come. Whether you choose machine washing, hand washing, or spot cleaning, always remember to use cold water, mild detergent, and air dry when possible.
