Nellies is the best laundry powder I tried this powder a couple years ago at my summer place that has a septic system and I wanted to make sure the laundry was as safe as possible. Tried it at various temperatures and love it. Clothes came out very clean and soft - no need for a fabric softener. I liked it so much when a tin of it (100 loads) was at my local Marshalls, I bought it and it will last for months. I have sensitive skin so it's also great for that. It is also unscented. I highly recommend it even if you don't have sensitive skin. It's environmentally friendly (recyclable tin can or in packets), works in hard and soft water, no need for a fabric softener and cost per load is very low. It comes in 50-200 size wash loads. I would never go back to a liquid laundry detergent.
