Fels Naptha Laundry Soap Bar & Stain Remover - Pack of 2 by Fels Naptha

This laundry bar works wonders! It managed to lift stubborn stains effortlessly without affecting the fabric color. I used it on handkerchiefs and a towel with blood stains (courtesy of a nosebleed), rubbed the bar directly onto the spots, left it on for about 30 minutes, and then tossed everything into a regular wash cycle. Voila – the stains disappeared, and the fabrics looked as good as new. The bars come in a set of two, which makes this an even better value for the price. I also appreciate that it isn’t harsh on my hands despite being effective on stains. Definitely a worthy buy to keep around for laundry emergencies.

If you are a baseball mom, you know that "white" pants are actually a cruel joke played on us by the universe. I used to look at the grass, clay, and unidentifiable dugout grime on my kid's uniform and consider just throwing the whole child away. Then I found this bar of magic. This isn’t just soap; it’s a miracle worker in a yellow wrapper. You just wet the bar, rub it on the disaster zone, and watch the stains admit defeat. It’s saved me a fortune in replacement pants and has successfully restored my sanity during tournament weekends. If you want your player to actually look like they started the game clean, you need this in your laundry room. It’s the MVP of every game!

Fels Naptha has been a trusted name in laundry stain removal for over a century. This pack includes two 5.0 oz bars of heavy-duty laundry soap designed to tackle stubborn stains, grime, and grease. Whether used as a pre-treatment for stains, a booster for homemade laundry detergents, or even for poison ivy relief, Fels Naptha is a versatile household essential. Pros & Cons Pros: ✅ Highly Effective Stain Removal – Fels Naptha is known for cutting through tough stains like grease, oil, sweat, dirt, grass, and food-based stains. It works particularly well on deeply set-in stains with minimal scrubbing. ✅ Multi-Purpose Usage – Beyond laundry, Fels Naptha can be used as a degreaser, a DIY laundry detergent ingredient, and even to alleviate skin irritation caused by poison ivy or oak. ✅ Long-Lasting & Economical – Unlike liquid stain removers that can be used up quickly, this solid soap bar lasts for months. A little goes a long way, making it a cost-effective option. ✅ Free of Harsh Bleach & Dyes – While powerful, Fels Naptha does not contain harsh bleaching agents, making it suitable for colored fabrics. It also lacks synthetic fragrances that can be overpowering in some commercial detergents. ✅ Easy to Use – Simply wet the fabric, rub the bar onto the stain, let it sit, and wash as usual. It’s straightforward and doesn’t require additional mixing or special equipment. Cons: ❌ Strong Scent – The bar has a distinctive, old-fashioned soap scent that some users may find overpowering. While it fades after washing, those sensitive to fragrances might prefer a milder alternative. ❌ Not Suitable for Delicate Fabrics – Due to its strong cleansing properties, Fels Naptha is too harsh for delicate fabrics like silk and wool. It’s best suited for cotton, polyester, and other durable materials. ❌ Requires Manual Effort – Unlike spray stain removers, using Fels Naptha requires scrubbing and pre-treatment, which might not be ideal for those seeking a quick, hands-off solution. ❌ Can Dry Out Hands – The soap’s deep-cleaning formula can be drying to the skin, so wearing gloves or moisturizing after use is recommended. ❌ Not Widely Available in All Stores – While popular, Fels Naptha is not as commonly stocked in major retail stores as liquid stain removers, meaning you may need to purchase it online or from specialty stores. Recommendations & Verdict Who Should Buy It? • Individuals looking for a powerful, affordable stain remover – If you frequently deal with tough stains from work, sports, or kids, Fels Naptha is a great option. • Homemade detergent enthusiasts – Many DIY laundry detergent recipes use Fels Naptha for its deep-cleaning abilities. • People with outdoor lifestyles – Hikers, gardeners, and mechanics who often deal with dirt, oil, or poison ivy exposure will find it useful. Who Might Want to Skip It? • People with sensitive skin – Due to its strong cleansing properties, those prone to skin irritation may prefer a gentler, fragrance-free stain remover. • Those looking for a quick, no-scrub solution – If you prefer a spray-and-wash approach, a liquid stain remover or detergent with built-in stain treatment might be a better fit. • Users of delicate fabrics – Since it can be too harsh on delicate materials, a gentler stain treatment is recommended for such garments. Final Rating: 4.5/5 ⭐⭐⭐⭐½ Fels Naptha remains a classic and highly effective stain remover that delivers excellent value for money. While it requires some manual effort and may not be suitable for all fabrics, its versatility, affordability, and stain-fighting power make it a must-have for many households.

I absolutely love Fels Naptha Laundry Soap. It’s incredibly effective and truly works like a miracle for tough stains. I’ve used it on everything from grease and food stains to baby messes, and it consistently gets clothes clean when nothing else works. A little goes a long way, making it very affordable and long-lasting. I also love how versatile it is—you can use it for pre-treating, handwashing, or even grating it into homemade laundry detergent. This is one of those old-school products that still outperforms so many modern options, and I always make sure to keep a bar on hand.

Brand new white pants (coach isn’t doing laundry) for 10U baseball. The first washing was great. I wet the dirty pants, scrubbed the bar directly onto the knees, pockets, seems, zipper, cuffs, rear, I mean, the entire pant, just one place at a time. Then let them wash and soak in regular detergent with shaved Fels Naptha in the wash water. After the cycle, I inspected the hard-fought dirty spots. Most were white again, however, some places weren’t clean enough for me. So, I proceeded to scrub the bar directly on the dirty spots again. After a second soak and wash, they looked new again!! Now, the second time they got dirty, the Fels Naptha seemed less effective. I also observed the condition of the knee area was very rough, unlike the rest of the pants. I’m not sure if the worn knees were due to my aggressive scrubbing or the soap itself. Additionally, the first time I used the soap, the top of one hand must have had soap residue that left a red, painful chemical burn. It’s true, this is strong soap, with a very clean soap scent. I recommend it for removing stains from Georgia red clay and baseball diamond brick dust.

Retro. Reminds me of my Nana. Very sudsy. Cuts grease as well as Dawn. Use in laundry for stain removal. Also soaking. It melts nicely. Light and pleasant smell. Can be difficult to find in stores.

Amazing product!! Got the stains out of my son’s pants on the first try. 10/10

One of the best stain removers on the market! Will lift stains on whites and colors gently, without the use of harsh chemicals. I’ve rubbed this soap on stained clothes, hand washed and rung it out, and even the toughest stains lift wonderfully. My hands don’t feel incredibly dry after washing and scrubbing the clothes, which is a big win. The fragrance is gentle and not overpowering of a “cleaner” smell. I bought the 2 pack of this stain boosting soap and it truly goes so far, I’m still working on my first bar! I like to leave this bar in the shower and will scrub down my stained clothes before the shower and wring & wash them in the shower, and it holds up just fine. I’ve also seen users use a grater and put this into their laundry - personally have done it once but the grating of the soap was a bit too much work for me, I am content with targeting stains as I see them. Even the toughest stains, like red dirt, lift away well with this!

It's like magic. Removes the stains I've tried it on.

This soap is wonderful for removing all stains - we have a lot with two small children at home!

I learned about the existence of this a couple of years ago and I am glad I did. This thing will remove those hard stains from clothes. Just wet the troublesome part, rub the soap, scrub the area for a moment and then put it in the washing machine. That should remove 80% of the stain and you can do it again to remove it completely. I only use it for hard to remove stains and I am very pleased with how well it works.

I first saw this soap on a YouTube video by Jinnie on Homestead Corner. I decided to purchase it on her recommendation. This is my second order and I love these bars for removing really nasty and tough stains including crude oil from my husbands pants. I spray with a little spray and wash, then rub with the bar of soap and scrub a bit with a toothbrush. I repeat again in a while, let it sit then toss in the washer and voila, stains gone! If by chance a stain is not totally gone when I take the garment out of the washer, I immediately repeat the process before drying (drying will set the stain). That usually does the trick! I have shared my soap bars with my sisters and they love them too!

This stuff is superb at getting rid of off white stains, it clean my white Under Armour top brilliantly.
