Hi MatkaII, The formula we use for our liquid wash does still protect delicate fabrics and fibers like lycra and elastic, as well as silks and wools! Like our powder, our liquid is designed to leave no chemical residue, which can degrade fibers. (FYI- for Lycra type fibers we recommended using cold or warm water with our liquid wash.)
To answer your question about how our liquid differs from our Forever New powder wash, it’s mostly just a difference of the types of washers being used. Liquid washes have become more popular with front loading washers, which are increasingly more common. The Holistia powder wash that we sold previously was a little different because it was all natural and unscented – our liquid is not all natural and does have a scent.
One benefit of the liquid wash that the powder didn’t have is that you can use the liquid as a concentrate to remove stains (safely) from your clothing.
Personally, I have used our liquid wash for the last 7+ years and absolutely love it! I do have a front loading washer and I find that a little goes an extremely long way (I also used it before getting my new washer in a top loading machine and it worked just as well there too). I use it on all of my delicates and they always last a very long time.
I hope all of this information helps, I think you will be very pleased if you decide to give our liquid wash a try. If you have any other questions I'd be happy to help here or you can call our Customer Service team at 1-888-282-6060. Thanks!
