How to Wash a Weighted Blanket with Glass Beads Filling

What is Microglass Bead Filling?

Weighted blankets get their extra heft due to fillings of small objects. While there are other options, microglass is one of the most viable when it comes to providing even, comfortable weight. They are very small and are similar in how they look and feel like white beach sand or salt crystals. It is heavier than plastic fillings, making it great for those who would like some weight on them but not suffer from the bulk.

Luckily, microglass bead filling washes very well, dries fast, and doesn’t clump up, rendering these weighted blankets good as new after every wash. This is good to know because what is inside your weighted blankets will have an effect on its washability and durability, and will also regulate the blanket’s soft, even pressure on your body.

Washing your weighted blankets does not have to mean breaking your back. However, you must take note, if a blanket weighs more than 12 lbs, commercial washers and dryers are your best options — unless your washing machine’s weight capacity can handle the load. Make sure to check your machine’s specs beforehand.

How to Wash the Detachable Cover and Inner Blanket of a Weighted Blanket

The detachable cover of Sonno Zona’s weighted blankets, which is made up of minky polyester in a deluxe duvet style, blocks dirt particles and stains from penetrating the inner blanket. Thus, the frequency of washing the inner blanket is reduced with the effect of better longevity.

Concurrently, the inner blanket, consisting of premium hypoallergenic cotton, is stitched to effectually contain the Bisphenol A (BPA)-free and lead-free glass beads.

Check the material of your inner blanket as different materials call for different washing procedures. But, for those who are using weighted blankets with microglass beads filling, proceed to reading the steps below.

Step 1: Sort and Spot-treat

The proper care of your blanket will ensure you will be enjoying it for a longer period of time. It is best to be aware of what kind of material your weighted blanket is made up of. Wash it appropriately by following the manufacturer’s instructions regarding its maintenance.

Wash weighted blankets separately. This prevents the chances of other items accidentally tearing your weighted blanket while in the washer.

Note that the instructions below are applicable to both detachable cover and inner blanket.

First, check for stains.

Treat the stains prior to washing, ideally even before they set into your blanket. Generally, holding the part of the fabric with a fresh stain under cold, running water can do the trick.

Specific treatment, though, will depend on the kind of stain.

There are stain removers available in the market that do not include harsh chemicals, which can ruin the weighted blankets’ fabric. Spray on the stained fabric, taking care to avoid rubbing the fabric together so as not to spread the stain; use a very soft brush instead.

An ordinary dish soap rubbed with fingers or a very soft brush on the fabric can work wonders on oil-based stains. Then, rinse immediately with cold running water.

Wash your entire blanket right after you have treated it for stains.

Step 2: Wash

Washing a weighted blanket

Unfasten the detachable cover from the inner blanket and machine wash it separately using the “Gentle” or “Delicates” cycle with cold water. A small amount of mild liquid detergent should be enough. Ditch the bleach and whitening agents, which may be too harsh on the fabric, and fabric softeners, which can damage the soft fibers.

If you prefer to hand-wash the weighted blanket, plunge the blanket in a big tub of soapy water and carefully knead. Once done, rinse the blanket by swishing in clean water repeatedly until the water runs clear.

Step 3: Dry

Tumble dry on “Low Heat” or “Air Fluff” to preserve the softness of the fabric.

As for hand-washing, squeeze the blanket by rolling, folding, and pressing on it to wring out the excess water. Refrain from wringing it so as not to alter its shape. Air dry the blanket on a flat surface or lay it out in the sun, making sure the weight is equally distributed.

Step 4: Fold

Now you can either fold for later use, or snuggle into your weighted blanket straight away once dry.

Step 5: Put Away That Iron

It is so convenient that ironing weighted blankets is not encouraged, as all types of heat treatment is not advised. These include dry cleaning or microwaving, or even washing with hot water. They can deflate soft threads or melt plastic pellets.


Learning how to wash a weighted blanket is not as daunting as you think.

To sum up, the best possible way to wash a weighted blanket is to place them separately in a washing machine at “Gentle” or “Delicates” setting. Use a mild detergent in cool water. Then either leave them to air dry on a large, clean surface, or use the tumble dryer on “Low Heat.”

As long as you’ve made sure your washer and dryer can support your blanket’s weight, and is on the right settings, there should be no problem in restoring your weighted blanket to its clean and fluffy glory.

However, before following any of the steps above, it pays to check the manufacturer’s individualized instructions on the tag or label with regard to the washing and care of the weighted blankets. It should always be followed with great attention.
