Well, I've given it a thorough test on anything and everything I could find, from my husbands work clothes, to soiled pet bedding, and...
I LOVE it. Seriously, it makes me want to do laundry more often! :) It has surpassed my expectations. My laundry is clean, smells amazing, and and is so soft!
I have been impressed with how it has whitened my whites, as well. I honestly think it does a better job cleaning than my previous Tide detergent.
So, if you have any doubts, try it for yourself! And let me know how you liked it. :)
