Can You Wash a Tranquility Weighted Blanket? (The Safe Guide)
I’ll be honest, I seriously considered just buying a new one to avoid dealing with this.
I took a whiff of my 15-pound weighted blanket the other day and realized something gross: it didn’t smell like “calm” anymore. It smelled like stale popcorn, old sweat, and specifically, my Golden Retriever. Looking at that heavy gray lump on my couch, I felt a wave of dread. Washing this thing felt less like laundry and more like industrial construction work.
So, can you wash a Tranquility weighted blanket without destroying your washing machine or the blanket itself?
I spent a frustrated weekend figuring this out so you don’t have to break your back (or your appliance). The short answer is yes, but it’s not as simple as tossing a t-shirt in the wash. If you do it wrong, you’re basically washing a bag of wet rocks.

The Verdict: Wash the cover, spot-clean the core. If you must wash the whole thing, use a commercial machine.

The “Anatomy” Check (Don’t Skip This)
Before you lug that heavy thing to the laundry room, unzip the side. Most Tranquility blankets consist of two parts: the soft outer cover and the weighted inner insert (usually filled with glass beads).
If yours is one piece (no zipper), godspeed. You have to wash the whole thing. But if it has a cover, your life just got 90% easier.
Tools You Actually Need
I’m not going to tell you to buy special “weighted blanket soap.” That’s marketing nonsense. Just grab these:
- Mild Liquid Detergent: Something gentle. (I used the sensitive skin stuff I already had).
- A Bathtub or Large Basin: Only if you are washing the weighted insert manually.
- Old Towels: You will need these to squeeze out water.
- A Sturdy Drying Rack: Or a couple of chairs pushed together.
Step 1: The Easy Part (The Cover)
Unzip the cover and peel it off the weighted insert. It’s like skinning a very heavy snake.
Throw the cover in your washing machine. Use cool water and a gentle cycle. Do not use high heat—it ruins the softness of the minky fabric. I threw mine in with a couple of towels to balance the load. Easy.

Step 2: The Hard Part (The Weighted Insert)
Here is where people mess up. Can you wash Tranquility weighted blanket inserts in a home machine? Technically, yes, if your machine is a beast. But I wouldn’t risk it.
Option A: The Spot Clean (Recommended)
If the insert isn’t soaked in something gross, just spot clean it. Mix water and detergent, scrub the spot with a toothbrush, and blot it dry. Done.
Option B: The Tub Soak (The “Fed Up” Method)
If the whole thing reeks, you have to submerge it.
- Fill the Tub: Fill your bathtub with cool water and a capful of detergent.
- Submerge: Push the blanket down. You’ll hear air bubbles escaping. It’s weirdly satisfying.
- Agitate: Stomp on it. Seriously. Get in there with your bare feet and tread water like you’re making wine. (My kids thought this was hilarious).
- Rinse: Drain the tub. Fill it again with clean water. Stomp again. Repeat until no more suds appear.
🧪 The Science: Why “Cool” Matters
Tranquility blankets usually use glass beads for weight. The beads are fine, but the polyester batting holding them in place is heat-sensitive. Hot water can break down the fibers or warp the internal grid, causing all the beads to slide to one corner. Then you just have a lumpy sack, not a weighted blanket.
Step 3: The Drying Nightmare
This is the part that takes forever. Wet weighted blankets are incredibly heavy. Lifting it out of the tub felt like a gym workout I didn’t sign up for.
Do not hang it vertically. If you hang it over a shower rod, gravity will pull the water (and the beads) down, stretching the fabric out of shape.
Lay it flat. I dragged mine outside and laid it across four patio chairs. If you are inside, lay it over a sturdy drying rack, but put towels underneath to catch the drips.

Reality Check: Is It Worth It?
Look, the result is great. My blanket smells fresh, and I sleep better knowing I’m not covered in dust mites. But it is a hassle.
If you have a stubborn stain on the inner weight, spot cleaning is 90% better than the tub soak. Only do the full soak once a year if you can help it.
The Lazy Alternative
Wash the cover. Then, drag the insert outside on a sunny day. UV rays kill bacteria naturally. Spray it with a little fabric sanitizer. Good enough for me.
FAQ: The Skeptic’s Corner
Can I put my Tranquility blanket in the dryer?
Only the cover! Put the cover on low heat. The weighted insert should air dry. The tumbling action combined with the weight can damage your dryer drum and the heat can ruin the bead pockets.
Can I take it to a laundromat?
Actually, yes. This is the “smart” way to do it. Commercial front-loaders can handle the weight much better than your home machine. Just skip the commercial dryer.
What if the beads start coming out?
Stop washing it immediately. If there is a leak, glass beads will get everywhere. It’s a nightmare to clean up (worse than glitter). Stitch the hole or replace the blanket.
Can I use bleach?
No. Bleach weakens the fibers that hold the heavy beads. Weak fibers = leaked beads. Stick to mild detergent.
