How To Wash A 20lb Weighted Blanket

You need to be extremely careful in how you wash a 20-pound weighted blanket. Most residential washers aren't designed to handle that kind of weight. You're likely going to need to take your blanket to a laundromat with a commercial washer to keep both your blanket and your washing machine safe.

Weighted blanket fills: Which are washable and which aren't?

From spills to stains, every weighted blanket gets dirty sooner or later. While these blankets are washable, you need to make sure you wash them the right way. Otherwise, you could end up doing more harm than good.
Weighted blankets require extra attention because in addition to the cover, they contain fillers inside. These fillers give the blankets weight. However, since fillers are made out of different materials, you need to be mindful of how they're washed.
For example, Snuggle Pro uses non-toxic glass beads for its weighted blankets. This material is safe in a washing machine. But the same can't be said for other fillers.

Micro glass beads

Snuggle Pro weighted blankets use glass beads as a filler material. These are tiny beads, resembling sand, that are safe for machine wash use.

Plastic poly pellets

Made from ABS virgin plastic, these pellets haven't been exposed to harmful chemicals or toxins. While they're smooth, they shouldn't be exposed to high temperatures. Exposure to heat could cause the pellets to melt, so only wash these kinds of blankets in cold water.

Steel shot beads

Some blankets are filled with smooth, steel balls. They're heavier than other materials, which puts your washing machine at risk. There's a possibility the blanket could tear open, causing the beads to fly everywhere and potentially damage your machine.

Organic substances

While rare, some weighted blankets use rice or corn as fillers. While it's organic, it also increases the risk of your blanket getting yeast or mold if you wash it.


Sand is typically a filler on cheaper weighted blankets. You can't really wash it since the sand absorbs water, causing it to clump together. There's also the risk of your blanket getting a tear and spreading sand all over your washer.

Cover materials differ widely—Here's how to wash them

There aren't many fillers you can trust in a washing machine. The same hold true for your blanket's cover materials. You don't want to risk damaging your blanket's cover or making it not as soft.


Snuggle Pro uses cotton as its weighted blanket cover material. It's breathable, keeping you comfy in winter and cool in summer. Cotton can go in the washing machine. You just want to use cold water and set it on a gentler cycle.


Silk weighted blankets are rare. It's a delicate material, so never put it in the washing machine. You should only ever wash silk by hand with cold water. You also want a mild detergent.


Wool is another delicate material. You should check the tag to see whether the manufacturer recommends putting the wool blanket in the washer. Since wool can shrink under certain conditions, you're often better off washing it by hand.


Flannel is breathable to keep you comfy all year round. While you can typically put it in the washer, you should pretreat any strains beforehand. Run the machine on a gentle cycle with cold water and a mild detergent.


Minky is a great material to have on a blanket when it's cold out. It has the amazing capability of retaining heat. You can wash it in a machine, but you should never use fabric softener. The cleaner could ruin the softness of the blanket.

Skip the dryer altogether, air drying is key!

There's a lot to keep in mind when washing your weighted blanket. And there are just as many considerations when figuring out how to dry it.
The general rule of thumb is to never put a weighted blanket in a dryer. This can cause the material to shrink. It can also degrade the fabric's softness.
Instead, you should air dry your weighted blanket. Here are some tips for making sure your blanket dries properly.
  • Place over a clothes rack or chair rather than a clothesline.
  • Lay the blanket out horizontally to avoid bunched-up filler.
  • Keep the weight evenly distributed.
  • Shake and flip the blanket every couple of hours.

Be mindful of the weight of your blanket

Weighted blankets tend to weigh between 5 and 30 pounds. It's recommended you get one that's 10 percent of your body weight.
The weight of your blanket also plays a role in how you should wash it. Some are simply too heavy to wash in a standard washing machine.

Weighted Blankets 5-10lbs

Standard washing machines can handle weighted blankets between 5 and 10 pounds. You just need to wash the blanket on its own in cold water.

Weighted Blankets 15lbs

Be careful with 15-pound weighted blankets. Your home's washing machine should be able to handle it, especially if you've washed heavy comforters in it in the past. Don't put anything else in the machine with a 15-pound blanket, and only use cold water.

Weighted Blankets 20lbs+

For a 20-pound weighted blanket, you generally want to wash it at the laundromat. Commercial washing machines are built for heavier loads. Give the blanket its own machine, and just use cold water.

Avoid these things when washing your weighted blanket

There are a lot of considerations to make when you need to wash your weighted blanket. That includes some extra tips for ensuring you don't accidentally damage your new favorite blanket.
  • Hot water - Excessive heat can shrink the blanket's cover material. The heat also has the potential of melting certain fillers, such as plastic poly pellets.
  • Fabric softener - You generally just want a mild detergent to clean the blanket. Fabric softener can ruin a blanket's softness, especially if the cover material is plush or minky.
  • Bleach - Under no circumstances should you use bleach on a weighted blanket. Even if the blanket is white, bleach is far too aggressive for the materials.

How to get specific stains out of your weighted blanket

Eating or drinking in bed may seem harmless. However, moving your legs ever so slightly could cause something to spill right on your weighted blanket. No matter what you spilled, stay calm and follow these simple directions.

Red Wine

  • Put 1 to 2 ounces of distilled white vinegar onto the stain.
  • Let the vinegar rest there for 5 to 10 minutes.
  • Use a wet towel to blot out the stain.
  • Dry off using a different towel.
  • Use an enzyme stain remover if the stain remains after completing the above steps.
  • Apply the enzyme stain remover and let is sit there for 30 minutes.
  • Blot out the remover using a wet towel.
  • Wash the blanket entirely using cold water.
  • Hang dry.


  • Mix 10 ounces of water with 1 ounce of laundry detergent and 1 ounce of distilled white vinegar.
  • Apply this solution to the stained area, gently rubbing it in using a washcloth or toothbrush.
  • Allow the solution to rest for 5 to 10 minutes.
  • Rinse thoroughly using cold water.
  • Repeat these steps as necessary until the stain is gone.


  • Apply soapy water to the stain.
  • For tougher stains, utilize an enzyme stain remover.
  • Pour some of the remover into the washing machine and run using cold water.
  • Wash it a second time if an odor remains.
