Thank you for these awesome ideas. I have used fels-naptha for many years as a laundry detergent and it does a wonderful job. wouldn’t use anything else. I love having more ways to use this great product. 🙂

It is FANTASTIC for poison ivy. I have a severe allergy to poison ivy. I had to be put on prednisone for it. Fels Naptha was the only thing thing got rid of it and gave me some relief.
Can I use Fels Naptha on a nylon, lycra black top? Concerned it will discolor the black which would be worse than the small stain.
I’m going to be honest and say I don’t know. I did some digging and don’t see a lot of information. I am so sorry! One lady siad she uses it on her sports jerseys that are Nylon based with no problems.
Any idea how to get rid of the smell from shampooing my carpet with Fels Napha, baking soda and castile. I have a reaction where my head hurts, eyes and throat irritated, and lungs feel bad and nose sorta burning feeling. Went over it twice with water, after it dried sprinkled baking soda all over and run an ozone generator. Still bothering me. Any help appreciated.
Some have added some essential oils when shampooing. We don’t have carpet any more so I don’t have any personal suggestions sadly.
I just heard that this soap can be bad for septic system. Do you have any information or comments about that? I used to make my own laundry detergent with Fels but haven’t for awhile, would like to start again.
Thank you.
We have a septic system and never had an issue. I also use RidX once a month too.
You can substitute yeast packets for ridx. Our plumber gave us this info.
