Purex Fels-Naptha is a laundry soap bar! It's good for removing stains off clothes. Only thing you got to do is get the laundry bar wet. Then before you add the stained up clothes in the washer apply laundry soap bar on your clothes, and then no more stains! It works wonderful. I tried it on mud, grass,wine, and food stains. All the stains walked right off my clothes. I recommend this to everyone young and old. Cheap too only a couple bucks at your local grocery store! To save on water use the bar so you have to rewash any clothes for the extra hard stains.
