I randomly came across this product and decided to give it a try to see how well it for my other half's collar stains. Until I received this product, very few products really helped reduce/get rid of the stains. Even when I found a product, it really required a lot of elbow grease to get rid of the stain.
I received this product in the mail and was skeptical. So I tried it on a few products, rubbed the product on a few of his shirts and threw it in the wash. I really didn't expect much but when I took it out of the wash, I was surprised that the little effort I put into taking out the stain really made a huge difference!
I highly recommend this product, especially for collar stains.
