I confess that I purchased one of those ridiculously overpriced high efficiency washing machines that could be related somehow to ET.They don't fill up with enough water to create a clean load OR dissolve detergent well OR rinse your laundry well.I have been using FOCA powder for many years because it is far and away more efficient than any of the big brands and at a much lesser cost. Unfortunately, it does not dissolve well in a high efficiency washing machine.I do not like liquid detergents and when I saw this on Amazon I was drawn by the reference to the claim that it will dissolve rapidly even in a high efficiency washer.OMG! I just love it! It actually does dissolve fully, and leaves the clothes very clean and smelling fresh.I dislike fabric softener because of the waxy buildup on clothes and damage it causes to dryers over the course of time. It is essentially perfumed wax. I like the smell of fabric softener however so sometimes I use a teeny tiny little bit. With this product, it does have the wonderful scent of Downy but very mildly so it is not overwhelming. It dissolves quickly and rinses thoroughly so the clothes and towels are fluffy and soft but not with that waxy feeling when you add fabric softener. Even without adding fabric softener, my laundry comes out nice and fluffy without a lot of static and clinginess.I am very highly impressed by this product and it is cost efficient as well.I have a tiny little dog that I take special care to wash her little dog clothes and furnishings only in very safe products. This one works quite well for her she doesn't exhibit any irritation from it.I really am impressed by this product and I will be ordering again.Handy Tip: I put the entire bag into one of those pet food dispensers and just open the top of the bag and put a measuring cup in it. This keeps any moisture / humidity from getting to the bag and prevents the detergent from clumping. It also makes it very easily storable in my tiny little laundry room.
