30 Ways to Use Fels-Naptha Soap

Is Fels Naptha Soap Safe?


Fels-Naptha was extremely popular during WW2 but over the years it dropped in popularity as convenience products made their ways to the shelves. Recently though it has seen a resurgence since so many people are starting to recognize the value of saving money with depression era money saving tips or money saving tricks from World War 2.

Fels Naptha is safe, however, it is a known eye and skin irritant with prolonged exposure. Also, while Fels-Naptha isn’t labeled as a nasal irritant, I find that grating it does irritate my nose quite a bit. Just keep that in mind when you’re looking for ways to use Fels-Naptha in your home. With all of that said, you will be fine as long as you aren’t sitting in a bucket of soapy water for hours. You can view the Fels Naptha MSDS sheet right HERE if you would like.

If you find that trying these uses for Fels-Naptha irritates you a bit more than you care for, you can give Zote soap a try.  Simple at Home  has an a really nice list of uses for  Zote soap HERE.

If your garden plants are being eaten alive (literally) by bugs, this may end up being your favorite of all of these ways to use Fels-Naptha. You can use it to make an insecticide that will kill the bugs on  your plants without harming the plant itself. Since commercial insecticides are so expensive, this is another great ways to save money around your home.

To kill bugs using Fels Naptha, grate a small chunk of Fels-Naptha then dissolve 3 tablespoons of the grated soap into 1 gallon of hot water. Allow the mixture to fully cool, add to a spray bottle and spray on your plants.


Use Fels-Naptha to repel bugs


Not only will Fels-Naptha kill bugs, but it can also repel them. To keep bugs away from your plants and home in general, cut a bar of Fels-Naptha into 1 inch chunks and place around the areas that you need to keep bugs out of.

For plants, you’ll want to place the chunk at the base of the plant, but be careful not to get it into the root area. This will work for garden bugs as well as moths and other creepy crawlers that can get into your home.

Use Fels-Naptha to repel mice 


Mickey causing too many issues in your home, but using mouse traps isn’t your cup of tea? Fels-Naptha to the rescue! Cut 1 inch chunks off of your bar and place them in areas where mice and other critters give you issues at. They won’t like the smell and will stay away. If you want to double up on the protection, add a few cotton balls covered in peppermint essential oil in different places. They won’t like that smell either.


Treat Chigger and mosquito bites with Fels-Naptha 


Chiggers and mosquitoes are pretty common pests during the warmer months of the year, but luckily Fels-Naptha can help relieve the itching from them!

To treat chigger and mosquito bites with Fels-Naptha, simply wash the area well with the soap. Rinse well and pat dry. The soap will help dry the bites up leading to relief for  you.

You also might want to consider using a homemade bug spray  or homemade citronella candles next time so you can prevent bites in the first place. If you’re like me, mosquitoes like to make you their dinner buffet.


Fels-Naptha can prevent poison ivy 


Not only can you dry up poison ivy, poison oak or poison sumac with Fels-Naptha, but you can also prevent it. Poison Ivy can stay on your clothing for up to a year after you’ve brushed against it even with commercial laundry detergents.

Washing exposed clothing with Fels-Naptha though can help remove any oils that are on the clothing and actually keep you from many itchy nights. Make sure to wash them separately from the rest of your laundry. Since we camp a lot, I keep a WonderWash on hand just for this. I don’t want to take the chance that the oils will transfer to my washer.


Clean grease and other things off of your hands with Fels-Naptha 


Know someone who deals with greasy hands on a regular basis? Lava hand soap works well but is twice the price of a bar of Fels-Naptha. Washing your hands with it can easily remove not only grease, but onion scents and other things that can stain or scent your hands.


Clean outdoor furniture with Fels-Naptha 


Outdoor furniture can get pretty funky over the course of just a few weeks and they are super expensive to replace. Instead of replacing them, clean then with Fels-Naptha.

Wet your furniture down and rub your outdoor furniture with either the bar itself of with a cleaning brush that has been rubbed across a bar then rinse thoroughly. We like to use this when we clean our outdoor furniture on a budget. It helps them stay looking great but keeps my budget in tact!


Treat mildew with Fels-Naptha 


Mildew is another thing that can befall not only your outdoor furniture but other areas in your home as well. Again, Fels-Naptha can be used to help clean it.

Wet the area down and spray with a bleach solution that is made up of 2 parts bleach and 1 part water. Let the bleach solution site for 10-15 minutes. Rub the area down with your bar of Fels-Naptha and scrub with a soft scrub brush. Rinse well and the mildew should be gone!


Lubricate squeaky door hinges 


The squeaky wheel gets the grease, right? Well, the squeaky door gets the soap. If you have a squeaky door hinge or knob, rub a dry bar of Fels-Naptha on the areas that squeak. Wipe off any excess and the squeaky wheels should fall silent. This is one of the best ways to use WD-40, but if you don’t have any on hand, Fels-Naptha will work well.


Use Fels-Naptha to clean your carpets 


One of my favorite ways to use Fels-Naptha is also one that will help you save money around your home. Commercial carpet shampoos are super expensive but Fels-Naptha is super budget friendly.

Just mix 1/2 cup grated Fels-Naptha with 2 gallons of water and heat to boiling. Allow it to cool completely and use it with a carpet shampooer to shampoo your carpets! As with any other carpet shampoo, be sure you check in a hidden are for color fastness.


Easily remove stickers and labels with Fels-Naptha 


The list of things thrifty people reuse is pretty big, but a staple item that gets reused is jars and bottles. Those jars and bottles usually have pretty strong labels and stickers on them though and they can be a pain in the rear to remove sometimes. You could buy Goo Gone, but Fels-Naptha can make it even easier.

Rub the seam of the label (where the glue is) or the entire sticker with a dry bar then let sit for a few minutes. Next, soak the jar in a bit of water with a bit of soap melted into it. Once you’ve soaked it for a bit, the label or sticker should peel right off.


Prevent lice with Fels-Naptha 


Now before I get into this, I want to remind you again that Fels-Naptha is a known skin and eye irritant. Please be careful if you choose to use this tip and if it harms your hair or eyes, neither Six Dollar Media, Inc. or I personally will be held responsible.

Some folks claim that Fels-Naptha can be used to prevent lice. To use it for this purpose, wash your hair with Fels-Naptha once a week. A much easier method is to add tea tree oil to your shampoo. Add 10-15 drops to each bottle of shampoo and conditioner, shake and shampoo/condition like normal.


Treat minor acne with Fels-Naptha 


Have a nasty pimple or zit? Wash the area with the pimple with Fels-Naptha. It will help dry out the oils in the pimple and help it to heal quicker. Rinse well with warm water and be sure to avoid your eyes.

If you would rather avoid using Fels Naptha on your face, consider giving our DIY Acne Mask with Essential Oils a try. It works so well!
