Review on 🌧️ Grangers Performance WASH: Top Choice by Global Leaders in Extreme Technical Outdoor Wear. Perfect for All Breathable Membrane Fabrics, like Gore-Tex and Event. by Brian Smith

Not advertised for use on duvets but I think it's the best. There is no lingering smell and the fluff is nice and fluffy after drying with dryer balls. very polite. If you wash the blankets with ordinary detergent, the feathers will clump together and will not dry well. It's not like this. VERY HAPPY with it. Have bought it multiple times. I wash duvets about 3-4 times a year. Of course I change and wash bed linen separately and more often! I'm sure you could wash the pillows with it (if they are washable). I wash king/queen comforters in the GIANT HE front loading washing machine in my basement and for this purpose I don't use the measuring cup cap on the detergent bottle, I use a liquid detergent dispenser and fill it in the appropriate detergent line to the size of the load and it works Perfect. DO NOT put fabric softener in the laundry!
