    When you use Fels-Naptha as a stain treatment, do you rinse it out before putting in the washer or do you just throw it in the washer with the Fels-Naptha still on it?

        Thanks for this update on pricing…but, don’t give up just yet! Try Ace Hardware or your local hardware store. If they do not have any on the shelf, ask if they can order some in. Also, check eBay to see if anyone is selling any Fels Naptha. It is definitely worth the effect as these bars last a long time! When you find some…stock up!!

    I have super sensitive skin, cannot use Noxema which removes a layer of skin and leaves my skin weeping serum, but have used Fels Naptha on my face, body, and hair with excellent results. I figured it would be ok for my skin, as my mom always washed us down with it when we got into poison ivy on camping trips. It leaves my face clean and soft, and my hair clean and shiny.

    I have used Fels Naptha bar soap for 40 to 50 years and somewhere along the line they changed the bar soap from “hard to lather to soft to lather”& the difference is that it does not clean or remove the oil from my body and for me that is a bad thing.
