Remove covers or cases
First of all you need to remove any pillow cases or covers from your feather pillows before putting them in the washing machine.
Place two pillows at a time
After removing the pillow case, you can put your feather pillow in the washing machine. However, you need to place two pillows at a time in the machine in order to even the load and keep it balanced. Then, turn the machine setting to cold or warm.
Add mild laundry detergent
Now you need to add mild laundry detergent. Pour half of the regular amount of detergent into the washer.
Run the machine on gentle or delicate settings
You are required to run the machine on gentle or mild settings. Then repeat the rinse cycle once or twice in order to thoroughly clean your feather pillows and remove all traces of detergent or soap from them.
Place the feather pillows in the dryer
Now, you need to place the feather pillows in the dryer and dry them. However, you need to add tennis balls or tennis shoes in the dryer with the pillows. The tennis shoes or balls will not only fluff up your feather pillows but will also protect the feathers from clustering.
Dry the feather pillows
After placing the feather pillows in the dryer, turn the heat settings to high and dry them. You need to keep them in there for one to three hours. It is advisable to check on them periodically, and monitor the drying process.
