I rarely write reviews but I was so glad I found this product! I work at an animal shelter. I always wash my work clothes separately because they get dirty and smelly. No matter what I tried, I could never get rid of the Funk smell. I found this stuff and decided it was worth a try. So glad I did! The smell from the box is a bit harsh for me (I use all unscented products), but I still felt like it. After washing and subsequent drying in the dryer, not only the odors of the shelter are removed, but also the strong smell that emanates directly from the product dissipates after going through the dryer. Everything turned out WITHOUT SMELL! HOORAY! I will never be without this product again!
