How to Wash a Weighted Blanket: Ultimate Step-by-Step Guide

Weighted blankets have gained popularity for their ability to reduce stress, improve sleep, and provide comfort. However, since they contain heavy materials like glass beads or plastic pellets, washing them requires special care. Improper cleaning can damage the fabric, affect the weight distribution, or even ruin the filling inside.

This guide will walk you through how to wash a weighted blanket based on its material, weight, and care label instructions. We’ll also cover how to spot-clean, dry, and maintain your weighted blanket to keep it fresh and long-lasting.

Why Proper Cleaning Matters

Weighted blankets are used frequently, making them prone to dirt, sweat, and bacteria buildup. Regular washing:

• Keeps the blanket fresh – Oils from your skin, dust, and pet hair can accumulate over time.
• Prevents odors – A clean blanket eliminates musty smells caused by moisture and sweat.
• Extends its lifespan – Proper washing techniques help maintain the fabric and inner filling.
• Reduces allergens – Dust mites and allergens can get trapped in the blanket’s material.

How Often Should You Wash a Weighted Blanket?

The frequency of washing depends on how often you use it and whether you use a cover.

• Every 1-2 weeks – If you don’t use a duvet cover, wash the weighted blanket more frequently.
• Every 1-2 months – If you use a duvet cover, remove and wash the cover regularly while washing the weighted blanket less often.
• Spot-clean as needed – For spills or stains, clean the affected area instead of washing the entire blanket.

Check the Care Label Before Washing

Before washing your weighted blanket, check the care tag for manufacturer instructions. Some blankets are machine washable, while others require hand washing or dry cleaning.

The label will tell you:

• Washing instructions (machine wash, hand wash, or dry clean)
• Temperature recommendations (cold, warm, or hot water)
• Drying methods (tumble dry, air dry, or no heat drying)

Ignoring these instructions can lead to shrinkage, fabric damage, or clumping of the filling.

Step-by-Step Guide: How to Wash a Weighted Blanket

The washing process depends on the material and filling type. Follow the steps below based on your specific blanket.

1. Determine If Your Washing Machine Can Handle the Weight

Weighted blankets can weigh between 5 to 30 pounds. Check your washer’s capacity before loading the blanket.

• Under 15 lbs: Can usually be washed in a standard household washing machine.
• 15-20 lbs: Requires a high-capacity or commercial washer.
• Over 20 lbs: Best washed in a laundromat’s industrial machine or hand-washed.

If your blanket is too heavy, washing it in a small machine can strain the motor and cause damage.

How to Wash a Weighted Blanket in a Washing Machine

If the care label allows machine washing, follow these steps:

1. Use the Right Detergent

• Choose a mild, bleach-free detergent to avoid damaging the fabric.
• Avoid fabric softeners, as they can build up and make the blanket feel stiff.

2. Select the Proper Wash Cycle

• Set the washer to a gentle or delicate cycle.
• Use cold or warm water to prevent shrinkage.
• If the blanket has stains, pre-treat stains with a small amount of detergent before washing.

3. Wash the Blanket Alone

• Do not overload the washer by adding other laundry.
• If needed, add a few towels to balance the load and prevent the blanket from getting twisted.

4. Rinse Thoroughly

• If detergent residue remains after washing, run an extra rinse cycle to remove any leftover soap.

How to Hand Wash a Weighted Blanket

For blankets that are too heavy or labeled hand wash only, follow these steps:

1. Fill a Bathtub with Water

• Use lukewarm or cold water to prevent shrinking.
• Add a small amount of mild detergent and mix it into the water.

2. Submerge and Soak

• Place the blanket in the water and gently agitate it to distribute the detergent.
• Let it soak for 10-15 minutes to break down dirt and oils.

3. Rinse Thoroughly

• Drain the soapy water and refill the tub with clean water.
• Gently squeeze the blanket to remove detergent, but do not wring or twist it, as this can damage the filling.

4. Press Out Excess Water

• Roll the blanket and press down firmly to remove excess water.
• Lay it flat on a towel and press again to absorb more moisture.

How to Dry a Weighted Blanket

Proper drying prevents mold, clumping, and fabric damage.

1. Air Drying (Recommended for Most Blankets)

• Lay the blanket flat on a drying rack or clean surface.
• Flip it every few hours to ensure even drying.
• Avoid hanging it by one edge, as the weight can cause stretching or damage.

2. Tumble Drying (Check Care Label First)

• If allowed, use a low heat setting in a large-capacity dryer.
• Place dryer balls or clean tennis balls inside to prevent clumping.
• Check the blanket every 30 minutes to avoid overheating.

3. Drying Heavy Blankets Over 20 lbs

• For extra-heavy blankets, air drying is best.
• If using a dryer, visit a commercial laundromat with industrial dryers.

How to Spot Clean a Weighted Blanket

For minor stains or spills, spot cleaning is more convenient than washing the entire blanket.

1. Blot the Stain Immediately

• Use a clean damp cloth to blot (not rub) the stain.
• Avoid soaking the area to prevent water from seeping into the filling.

2. Apply a Gentle Stain Remover

• Use a mix of mild detergent and water or a stain remover.
• Gently scrub with a soft brush or sponge.

3. Wipe and Dry

• Wipe with a damp cloth to remove residue.
• Let the blanket air dry completely before use.

• Fleece – Wash in cold water, air dry to maintain softness.
• Minky fabric – Use cold water and avoid fabric softeners.
• Bamboo or rayon – Wash gently and air dry to prevent shrinking.

Tips to Keep Your Weighted Blanket Clean Longer

• Use a duvet cover – Protects the blanket and makes washing easier.
• Avoid eating or drinking on the blanket – Reduces stains and spills.
• Shake out dust and debris weekly – Keeps it fresh between washes.
