We made our Kuseno Weighted Blanket as simple as possible to clean.
For quick cleaning of the outer cover, simply remove the outer cover and machine wash it with cool or warm water, then tumble dry. Cotton outer covers can be ironed on high with or without steam. Flannel covers are best fresh out of the dryer, but can be ironed if you use a pressing cloth and iron on the wrong side of the fabric with medium (wool setting) heat.
For more thorough cleaning, remove the outer cover and then remove the weight bags from the pockets of the inner blanket. Wash and dry the inner blanket with cool or warm water and tumble dry. You can iron the empty inner blanket.
If the weight bags become soiled, it's easiest to hand wash them and air dry or tumble dry on low to medium heat.
Can you machine wash the entire blanket without removing the weight bags? Yes you can, and it won't harm the blanket at all! Be sure to balance the load properly, especially with a heavy blanket.
Disclaimer: Kuseno Comfort Products and its owners and employees cannot be held responsible for any damage caused to your appliances as a result of use or misuse of the blanket. Our recommendation is to always remove the weight bags before washing. This is, afterall, one of the many advantages to removable weights in a weighted blanket.
How to fill the pockets and secure the outer cover:
Will the plastic pellets melt in the dryer?
The melting point of the HDPE Plastic is 120-180 °C (248-356 °F).
A dryer on High/Cotton Setting is 57 °C (135 °F).
An iron on High/Cotton Setting is 204 °C (400 °F).
It's not likely that the plastic pellets will melt in the dryer, but they could melt if you iron them. Don't iron the weight bags.
