What is Fels-Naptha?

Fels-Naptha is a brand of bar-style laundry soap that is currently manufactured by the Dial Corporation. It's used primarily for pre-treating laundry stains. It's also believed to be helpful for treating poison ivy and other skin-irritating conditions.

Fels-Naptha soap was first created by Fels & Company of Philadelphia in the late 19th century. Originally, Fels-Naptha contained naptha, a flammable liquid that is made from distilled petroleum. Naptha has many industrial uses, such as lubrication of oil pipelines as well as the processing of high-octane gas and lighter fluid.

Although the inclusion of naptha into Fels-Naptha soap increased its efficiency as a cleaner, it was eventually removed as a potential cancer risk. However, even without the substance that gave it its name, the soap remains an effective laundry aid and a popular addition to homemade laundry detergent recipes.

Using Fels-Naptha as a Stain Remover

On its own, Fels-Naptha bar soap is an excellent stain remover and pre-treatment for laundry. It effectively removes many types of stains, including some of the most stubborn such as grass, mud, blood and red wine.

To use the soap as a stain remover, wet one corner of the bar and rub directly onto stained clothing. Alternatively, use an old toothbrush, rub it into the bar of soap with a bit of water, then scrub out the stain with the toothbrush.
