Rockin’ Green Dirty Diaper Laundry Detergent (45oz) Bundle with Classic Rock Laundry Detergent (45oz) | All-Natural and Vegan | Unscented and Fragrance Free | Safe for Cloth Diaper & Sensitive Skin

I use this to wash my kid's clothes. It's super concentrate, it's scent-free and I would say it lasts a long time.

I have an elderly dog who is punitively incontinent (or so it seems at times.) LJ is now a daily diaper wearer, and we use the washable ones. Well. I have not every dealt with diapers, and let's just say it was a BIG SURPRISE to wash them twice, and to find that still they smelled unpleasant. We tried a couple of different things with not much luck, but this has worked for us and LJ. We use two scoops and a hot wash, and LJ's diapers are much improved. No more urine smell. I am not sure how much LJ appreciates it as he likes stinky things, but his "parents" are very happy. This stuff is on repeat order for our house.
