What is Fels-Naptha soap?

Fels-Naptha is a laundry bar manufactured by Purex. It works to remove oily stains, grease, perspiration and ring-around-the-collar. Purex Fels-Naptha has been used in America for more than 100 years. The bar is 5.5 ounces and can be typically found in the laundry aisle of many stores.

Purex Fels-Naptha is easy to use. Simply wet the bar and rub it on the stain. Allow it to sit for a few minutes and wash the clothes as normal. Fels-Naptha can be used as a laundry booster by finely grating it and adding up to a half bar to the washer. It can be used as a pre-treatment and is safe to use with chlorine bleach.
