 Just like the washcloth test we do. We come out and we ask you to give us a washcloth that you've washed in your wash machine. And then we rinse it in soft water and show you all the trapped soap.

How many people out there fight skin irritation in the summertime and you're going to the doctor and the first thing the doctor asks you is what type of laundry soap you're using? Hmm.
