Product review (4 stars): Works as advertised - Satisfied!
My wife and I did not want my garage rags in our home laundry machine(s) so I ordered this.  Got it out of the box and immediately put some of my garage rags (dirty not filthy/greasy - I throw those ones away.) in a five gallon bucket, added some detergent and went to work.  I was very happy to see the dirt removed in a few minutes from the agitation and more dirt removed from my rinse "cycle."  I rung out the rags and lay them on the driveway in the hot sun to dry and was pleased at how clean they looked.  They didn't smell as fresh as the laundry inside our home but for garage rags, I am very satisfied.  Also in an power out situation it would be nice to have this around.
