I received in the mail as part of being a Purex Insider FELS-NAPTHA which is a laundry bar and stain remover. I know with kids and just being clumsy we all have stains which are very stubborn to come out whether it is food, grease, grass, dirt, oily stains, perspiration and so much more. The way you use this laundry bar is wet the bar and rub the stain you are trying to get out if it is heavily soiled use a soft brush to help get deeper in to the area. I can tell you I am a messy eater sometimes and wear it on my clothing my husband would say “I can dress you up but I can’t take you out” and some of the stains on my clothes. I love the smell of this bar and it made my clothes brighter and helped with removing stains I have and gentle on my clothes, it has many uses. Visit http://www.purex.com/products/
laundry-enhancers/fels-naptha to learn more. Being around over 100 years and started by the townspeople of Yancyville, North Carolina when the economy was floundering. Besides being uses for laundry it has many uses such as poison ivy prevention, clean the shower, tanning hides, deer repellant, wash dishes and pesticide. So I highly recommend this product to you to try for laundry and any of the other uses it has you will be surprised at how great this works.
