I am very particular about my laundry; and I must admit I was skeptical about using only one and a half teaspoons of this powder. BUT, Meliora Laundry Power is as powerful as the liquid, plastic-packaged, heavy-carbon footprint laundry soap I used to buy. What I like about it most is my machine stays clean (NO residue) and my clothes are as bright as the liquid soaps I previously used. It's a feel good product - my laundry is super clean and my conscience is freed from heavy-carbon footprint detergents I used in the past. This product is a winner in my book!
