Sure is, but I don't own it..just read about it, used it and found it good...much like everything else that I've tried.
It's excellent on all that and I have found no downside to it except dingy whites..some state they take care of that with putting vinegar in the rinse water. I took care of it by buying colored bras, undies and socks. I like
final solutions, as you may have noticed.
Don't like fussy little routines for things and if it can't be done quickly and efficiently, I usually don't do it unless maybe making my own breads. I like that process so much that I will take the time to do it. It soothes me!
I use the original recipe of Fels Naptha, Borax and A&H washing soda(not baking soda)~the liquid version. I live in a humid climate, so the powder version would cake up for me and be like a brick by the time I hit bottom of the bucket. I also like how the liquid dissolves in the wash, as I don't often use hot water and the soap may not dissolve all the way in cold.
Been doing this for nigh on 7 years I think...I would never go back to regular detergents. This is so cheap and leaves my clothes so clean smelling...like cloth instead of perfume..and the clothes are not stiff with detergents so if you hang them out to dry they don't stiffen up as badly. And I can wash a load of laundry for about $.02 a load and that can't be beat. I love the smell in the house when I'm cooking this soap down and I like the feeling of having several jugs on the larder shelves, not having to remember to buy detergent at the store, and not having to throw away my detergent jugs. I've got some I've been using for the entire 7 years...those things just don't deteriorate much.
Not much of a downside to it and it got my boy's clothes clean and that's saying a lot! It's good for the septic system as well, so it's all a win/win/win/win/win...well, you get the picture.
