Weighted blankets are a perfect go-to for cozy nights and better sleep, so the last thing anyone wants is to ruin them while washing. The good news? Washing a weighted blanket at home is totally doable. You just need to know the right steps and use the right detergent. Here's exactly how to wash a weighted blanket without wrecking the blanket you love.
Before you start: check the care label
Every weighted blanket is a little different. Before anything else, flip your blanket over and find the care label. It will tell you how to wash the weighted blanket, the recommended water temperature, and whether it's machine washable or dry-clean only.
Most weighted blankets (typically 12–20 lbs) can be washed at home in a large-capacity front-load washer. If yours is heavier than 20 lbs, a commercial laundromat machine is your safest bet.
Steps to wash a weighted blanket
Use the best detergent for weighted blankets and follow these simple 7 steps to wash with care.
Step 1: Check for damage first
Before you start washing the blanket, look for any loose seams, tears, openings near fillings, or plastic pellets that could escape during the wash. Even a small hole can turn into a big mess (and a broken washing machine). If you spot any damage, do a quick hand stitch to close it up before washing.
Step 2: Pre-treat any stains
Got a spot from last night's snack or a mystery stain you'd rather not think about? Tackle it before the main wash. Apply a small amount of detergent directly to the stain, gently work it in with your fingers or a soft brush, and let it sit for 10-15 minutes.
This is where your detergent choice really matters. You want something that's tough on stains but gentle enough not to break down the fabric or irritate your skin, especially important for a blanket you're snuggling with every night.
Mozi Wash is a great fit here. It's a concentrated, plant-based formula that's free of parabens, phthalates, and phosphates, with no hormone disruptors and no harsh chemicals that could damage delicate weighted blanket fabric over time. Mozi Wash has clean, effective ingredients that actually work.
Step 3: Load it properly into the washer
How you place the blanket into the drum affects the entire cleaning process. Keep it loose and avoid folding it. The blanket needs space to move around so the water and detergent can clean it properly.
If you have to push the blanket to fit into the drum, it is a sign that the machine is too small for the blanket. Overloading the machine can stress the motor and hinder proper cleaning. You may either switch to a bigger machine or go for laundry cleaning.
Tip: Wash the blanket alone. Don't add clothes or other linens, as it may affect the cleaning of the blanket and cause clumping.
Step 4: Add the right amount of detergent
This is where a lot of people go wrong: they use too much detergent, which leaves residue in the filling and can make the blanket feel stiff or heavy.
With Mozi Wash, you only need 1-2 tablespoons per load, even for something as bulky as a weighted blanket. Because it's ultra-concentrated, a little goes a long way. Pour it directly into the detergent drawer or drum before loading your blanket.
The low-sudsing formula of Mozi Wash makes it a fit for an HE machine as well. Whether you are using cold or warm water, it works effectively.
Step 5: Choose the gentle cycle and cold water
For washing weighted blankets in the machine, set the machine on gentle or delicate cleaning. Try to use cold water, as hot water can break the fillings over time and shrink the outer fabric. Cold water is safer for the material and still gets the blanket clean when paired with a good detergent.
Avoid any "sanitize" or "heavy duty" cycle options; those are too aggressive for a weighted blanket and can do more harm than good.
Step 6: Run an extra rinse cycle
Typically, weighted blankets hold a lot of water. After the main wash cycle is over, you may run one more rinse so that all the detergent is fully flushed out of the blanket. If detergent is left behind, it may cause skin irritation and odors over time.
This step is especially worth it if your blanket is on the heavier side. A second rinse takes only a few extra minutes but makes a noticeable difference in how fresh and soft your blanket feels coming out of the wash.
Step 7: Dry it low and slow
Now for the most important part: drying. Weighted blankets need to dry completely. Damp filling is the number one cause of mold and mildew inside these blankets, and you won't even know it's there until it's a problem.
Set your dryer to low heat and expect the process to take some time, probably longer depending on the weight. Every 25-30 minutes, pull the blanket out and give it a good shake to redistribute the filling so it dries evenly and doesn't clump in the corners.
If it's a sunny day, air drying flat on a clean surface works great too, just make sure it's fully dry before you fold it up or put it back on the bed.
A few more tips to keep in mind
How often should you wash a weighted blanket? Every 1-2 months is a good rule for regular use, or more frequently if someone has been sick or if it is used daily without a cover.
-
Use a duvet cover
Putting a removable cover over your weighted blanket dramatically cuts down on how often the blanket itself needs to be washed. The cover can be tossed in the laundry weekly, or even monthly, with your regular bedding.
-
Skip the fabric softener
Fabric softener can coat the filling and reduce the blanket's breathability. A quality detergent like Mozi Wash handles softness and freshness on its own, without the buildup.
The right detergent makes all the difference
Weighted blankets are an investment. The last thing you want is to wear one out prematurely with a harsh, chemical-heavy detergent. Mozi Wash is built for exactly this kind of laundry.
It's plant-based, paraben-free, phthalate-free, safe for sensitive skin, safe for your blanket fabric, and safe for the environment. And because it's ultra-concentrated, one bottle gets you 50+ loads, so you're not burning through it quickly.
Also, the scents are inspired by real perfumes and colognes. Imagine pulling your freshly washed weighted blanket out of the dryer, and it smells like Cozy Cashmere or Vanilla Moon. Washing your weighted blanket doesn't have to be stressful with simple care steps. Shop at Mozi Wash today.
