How to Wash a Weighted Blanket in a Machine

Weighted blankets are great for alleviating symptoms of ADHD, anxiety, or even insomnia (1). However, to fully maximize their potential, you need to keep them clean.

If your weighted blanket weighs less than 25 pounds, you should be able to throw it into your washing machine. However, the washing machine should be large enough to hold a king-size comforter. The washing instructions vary according to the materials of the blanket.

Usually, the blankets come with fabric duvets, and these duvets are the parts you need to wash regularly. So unless there has been a spill or something, you don’t have to clean a weighted blanket.

Washing the Blanket Cover

First of all, you need to check the type of fabric. Different fabrics can’t take the same water temperature, detergent strength, and washing strength. Thus, you need to distinguish the instructions. It's super simple:

  • Cotton: Cotton blankets are the simplest and should be washed like your usual laundry. You can use either warm or cold water, put in your regular detergent, and start the machine on the normal cycle. Do not use any fabric softener.
  • Fur/Plush/Mink: You can use warm or cold water for these soft fabrics, and you can also use a regular detergent. Just be careful to use only the gentle wash cycle on your washing machine. 
  • Wool: When washing wool covers, you should only use cold water. You can put the machine on the gentle or hand wash cycle with a wool wash detergent. 
  • Silk: As luxurious as silk is, it requires extra care. You should wash these in cold water with the hand wash cycle and use a gentle detergent. We recommend dry cleaning for silk covers.
  • Rayon: You can wash your rayon covers in cold water with a regular detergent. However, you must put the machine in gentle or hand wash settings.

Washing the Weighted Blanket

The weighted blanket itself does not need to be cleaned that regularly. If there has been an accidental spill, you need to check the filling material. This material will determine how you clean the weighted blanket. Some fillings can only be hand-washed, while you can not wash others at all and need to employ spot cleaning. Here's what you should do:

  • Glass Bead Filling: You can wash a weighted blanket with glass beads in either warm or cold water. You should use a bleach-free detergent with no fabric softener.
  • Plastic Pallet Filling: You can only use cold water to clean these blankets.
  • Steel Shot/ Smooth Pebble Filling: Unfortunately, you can not wash these in a machine, and they can only be hand washed.
  • Organic Material/Sand Filling: you can not wash these weighted blankets at all. In case there is a stain, you can only spot clean.

How to Wash a Weighted Blanket by Hand

Some blankets are made from such sensitive materials that you can not wash them in a machine at all. You need to wash these by hand. But, don’t worry just yet. We have a way for you to do that as well:

  • Fill your bathtub with warm or cold water.
  • Put in the detergent and mix it in with your hand.
  • Put your blanket into the water and make sure it is submerged. Afterward, leave it to soak for 15 minutes.
  • After 15 minutes, drain the water and replace it with fresh water. Resubmerge the blanket and keep doing the same thing till there is no more detergent.
  • Squeeze out the remaining water without wringing the blanket.  

How to Spot Clean a Weighted Blanket

Sometimes blankets do not need a wash at all, and you can simply treat the stains instead. For that, you need to cover the stain with a stain remover. Work the stain remover into the fabric and leave it to do its work. Afterward, clean the stain, and your blanket will be as good as new.

How to Dry a Weighted Blanket

There are two methods that you can use to dry a weighted blanket:

  • Machine Dry: You can only machine dry your weighted blanket if it has a glass bead filling. Even then, you should only do so using low heat.
  • Air Dry: Your blanket has been washed, and you're ready to hang it on a clothesline for air drying. STOP! You’ll shift the filling and get a lumpy blanket after all your hard work. Therefore, for air drying, lay your blanket flat on a plastic sheet and let it dry. You can shift it from time to time to speed up the process.

The next logical step looks like ironing the blanket because those wrinkles look awful. But it is not. If you iron your blanket, you’ll damage the filling and have to replace the entire blanket. Just leave the wrinkles. It’s okay. Put the cover back on and go to sleep.

Do I Need to Use a Laundromat to Wash a Weighted Blanket?

If your blanket weighs more than 25 pounds or if you have a small washing machine, using a laundromat might be the better idea. Moreover, commercial laundromats are generally better equipped for heavy-duty washes anyway. If you are unsure about your machine, you should use a commercial one as these are bigger and are less likely to be damaged by a blanket.
