Review of Acoustic Blankets Mounting Tracks

I suggest you to take the blankets to a Laundromat and wash in a commercial washer with regular amount of detergent. Do not put too much detergent, because your blankets will start smelling like Laundromat!
Then dry them in a tumble dry at high heat.I suggest to go through several 12 minutes cycles, so you can straighten up the blanket in between the drying cycles.
