As a Purex Insider, I got to test their new product Purex Complete With Zout. This is detergent with pre-treater in one. You can use this product directly to a stain or add to your washing machine with your load.
This product has three powerful stain-fighting enzymes to attack different types of stains. Protease works against protein based stains such as grass and blood. Amylase works against starchy stain like chocolate and tomato sauce. It also has Mannanase that works against guar, sticky stains ground in the fabric.
I liked how Purex Complete With Zout handled getting fresh ketchup out a shirt without needing a repeat application. However, you can try this product for yourself. For a free sample, go to http://www.freesamplepurex.com/freesample/
