It works

I have 2 stinky boys, and a stinky spouse. (I always smell like flowers, though :-)
This has been really effective. I like the scent--it's pretty gender neutral. I would like a more lightly scented option, if they expand the line. Still, I'll stick with it. I love how little is needed, and that the bottle is recyclable.

This stuff works!

Cleans well, no scary ingredients, smells great, less plastic. I've switched to Dirty Labs! Cancer survivor who is cleaning things up! So glad I found Dirty Labs!

Surprisingly lovely scent

So far I’m loving the product. I thought the scented option would be off putting but I’m really enjoying it. My husband used it while I was away on vacation and he didn’t read the instructions and put WAAAAAY too much in. Now our bed linen has a really strong smell. I’m sure it will wash out.

Disappointed

As a family with 5 boys, two dogs, and an elderly cat with litter box issues, I *really* looked forward to experiencing the wonderful cleaning power promised by the company and rave reviews. Unfortunately, whether with one capful or two, it doesn't seem to clean as well as other detergents we use (All, Kirkland brand, etc...). Additionally, I LOVE the smell of cedar and hoped to enjoy a new scent on our laundry. However, my husband and I both independently came to the conclusion that the scent left on the clothes from this detergent actually smells musty. It was better than using nothing, as the clothes were reasonably, though not perfectly, clean so I give it 2 stars rather than 1.
