10 Things You Should Know Before Making Homemade Laundry Detergent

by Ivory Soap on 05/30/2012

Thank you for visiting Little House in the Suburbs. If you like what you see, please check out OUR BOOK.

I have spent HOURS on the this database researching all of the possible chemical formulations of laundry detergent, and like dishwasher detergent, it has completely CHANGED how I make homemade laundry detergent!

Cleaning Power

1. NO commercial detergents contain BORAX and WASHING SODA together.

It’s an either/or.   Powder is washing soda.  Liquid detergents have borax, usually with alcohol.  End of story.  My guess is that washing soda loses its poop over time in water and borax doesn’t.

This may also be why powder detergents are supposed to be more effective than liquid.  Borax only lets the cleaning pH go up so far.  And borax is most effective in hotter water, so since most people wash in cold these days, it’s not useful enough to include in commercial detergent unless it’s pre-dissolved in a liquid?

Conclusion:  Borax is fine, but if you’re having trouble getting things CLEAN (which is not the same as WHITE), replacing borax with washing soda will make it more powerful.  If you want to make liquid detergent, washing soda may not be a good choice, however, I have no idea how that alcohol/borax thing works out.  Good luck.

2.  Only Purex and Seventh Generation use salt.  Nobody else does.

Purex powder is almost 50% salt.  Seventh Generation uses a tiny amount in some of their liquids.  Salt *is* a water softener, but it’s WAY weaker than washing soda.

Conclusion:  If it works for you, great.  But if you’re having problems getting things CLEAN, ditch the salt and put in more washing soda.

3.  NO detergents contain BAKING SODA

Not even Arm and Hammer.  Baking soda is only half as strong as washing soda at softening water and doesn’t allow the cleaning pH to go nearly as high.   And if you have a stronger product on hand, why dilute it with a weaker one?

Conclusion: Like salt, and borax, if you’re having trouble getting something clean, eliminate the baking soda and replace with washing soda.  But if you’re washing delicates, tossing in a buffer like baking soda is a good idea!

4.  ALMOST ALL commercial detergents contained some kind of SOAP or NON-SOAP detergent

Grate up that Ivory (SUPER FINE so it dissolves well) or whatever you have around.  Pure tallow or lard soap has less cleaning power than anything made from coconut oil, but coconut oil is super bubbly.  Ivory is a split between the two.  I love it.

5.  Most detergents contain enzymes. (UPDATE 7/4/2012:  Old timers use MEAT TENDERIZER for protein enzymes.  I don’t know how it would do IN your washer, but it would work just fine in a soak!)

Enzymes eat your protein stains. You can buy Biz or another enzyme cleaner and add it in, OR you *could* make your own.  These enzymes are from cultured bacteria from three places:

  1. B. Subtilis, which is found in ropy bread (a type of spoiled) and the Japanese food, Natto.  You could culture it from that if you like.  Red Devil Drain Maintainer liquid, and Rid-X Septic System treatment Ultra Liquid are both 100% Subtilis bacteria.  If you have easy access to any of those, a tiny squirt in your wash should be AMAZING.
  2. B. Lichenformis, which is found in the chest feathers of ground dwelling birds and somehow contributes to their molting schedule.  I am totally going to swab the chicks and try to grow that for fun.
  3. B. Cereus, which is not widely used yet, but comes from un-canned fermented cabbage.  Cultured kraut juice should do the trick.  Maybe buzz and strain some of the kraut itself it for more power.

I’m going to make all three with the kids this summer for fun!  I’ll tell you how it goes…

Conclusion:  It’s hard to get out many stains without an enzyme cleaner.  Buy one unless you want to culture one of the above three bacteria.

Now, Let’s Talk Whites

6. ONLY powdered commercial detergents use an oxygen bleach. 

Oxiclean looses it’s poop in liquid form.  You can make your own Oxiclean POWDER by mixing peroxide and washing soda and dehydrating it, but there’s really no point.  In water, Oxiclean becomes peroxide and washing soda.  It’s easier to just dump peroxide in your bleach compartment or make a solution of half peroxide half washing soda for immediate use on stains.  Probably more frugal is a scoop of Dollar store Oxiclean.  Borax has been touted as an oxygen bleach but it’s weak and doesn’t work in cold water at all.

7. Vinegar dissolves the salt deposits on your clothes. 

You can just put ½ cup in your rinse compartment, but it you have really hard water and a top loader, it might not be enough vinegar to make a dent.

8. ONLY Tide Tablets (old product) contain CITRIC ACID. 

As you add more acid to the mix, and decrease the possibility of deposits, you are neutralizing the washing soda.   To use it with washing soda, you have to overwhelm the citric acid with washing soda to make sure there’s enough left to do it’s high pH cleaning thing.   In Tide Tablets, it’s at least a 4 parts washing soda to 1 part citric acid.

Conclusion:  Use 1 cup of washing soda for each 1/4 cup citric acid.  If I still get sediment, use more detergent, and switch the acid in the rinse compartment to citric acid.

9.  Whites aren’t REALLY white in the real world.  

Most whiteness is an ILLUSION.  There’s two fancy chemical families in most commercial detergents that trick your eyes into seeing WHITE.  They boil down to BLUING and FLUORESCING.

  • BLUING has been around forever.  Most white garments come from the store with BLUING in that eventually wears off.  This bluing DYE counteracts the natural yellow cast.  If you want that brilliant white back, you need to BLUE it periodically with THIS or use a combination commercial product that has that effect.
  • Another option is FLUORESCING, often tagged as “optical brighteners.”  This is in Zote soap.  These chemicals activate in light.  So if you soak something in Zote (or any other product with brighteners) and put it in the sun….it gets REALLY bright.

But, but…. 

10.  If you really think it’s not getting clean try using T.A.C.T.

Temperature, Agitation, Chemistry, Time:

  • Increase the temperature of the wash water. Oils especially don’t want to come out in cold water.
  • Put your detergent in FIRST and less clothes in the wash so they tumble better.
  • Use more detergent and/or make sure the detergent you are using is rinsed well
  • Soak the load before you run it.

For me, I use half washing soda and half grated Ivory or homemade lard/coconut oil soap…REALLY FINE GRATED. The older your soap (even Ivory), the more brittle and easy to grind. 3T in the washer, 1/2 cup vinegar in the rinse. For lights and whites, I use hot water, 1/2 cup peroxide in the bleach compartment, unless I have the presence of mind to remember the Dollar Store Oxiclean.

I was out looking for what is really in “New Age Biodegradeable Household Cleaner”, which has been my “soap” source for many years. The label says “water, coconut oil, lemon oil, wetting agents, citric acid”, but I always thought you needed lye to turn oil into soap. Or a fancy reactor and heat and hydrogen… And I thought “wetting agents” was another term for detergent. But it seems to work well and has only a slight lemony scent that doesn’t stick to things.

Interesting to see this discussion of washing soda and borax! I use roughly equal proportions for laundry in my ancient front-loader with _very_ hard water. Agitate the powders in the water first, to deal with the hardness, and then add enough New Age to just barely foam, and then the clothes. The EWG “Guide to Healthy Cleaning” says borax is nasty, but it seems if I don’t use it the gooey hard water residue coats my clothes.

For the people mentioning sodium percarbonate, supposedly OxyBoost is at least 80-90% sodium percarbonate, while Oxiclean contains about 50-60%. You can buy the 100% stuff in bulk several places on the web. Search eBay for “Koi Pond & Waterfall Cleaner”, where I just bought 10 pounds delivered for $27. Yes, it is amazing for killing string algae and brightening wood decks, as well as laundry. But if you’re using more than is required to oxidize your stains, it becomes just an expensive form of washing soda.

thanks for all your research!!!

Tess April 17, 2013 at 1:06 pm

Hi there,

I’m in the UK and TOTALLY love this post… I am trying to justify making my own detergent but all the ingredients seem to come in smaller, more expensive versions here…. Can anyone tell me what would be a good source for the biological enzymes other than just buying a super cheap bio powder to add to my mix? Thanks!

Dawn maness April 30, 2013 at 10:34 am

I have had Borax ruin clothing so I’m curious when people use it. ..Do you put in washer then turn on water then add clothes.

Sommer May 12, 2013 at 3:50 pm

I’ve been making my own laundry detergent for about a year now. it consists of fells naptha, Arm and Hammer washing soda and borax. with a cup of each and a bar of the soap I get 5 gallons of detergent. I’ve never had a problem with any of our clothes ruining. Maybe for those who have had issues with borax, it could be that there was too much of it used. Or maybe I should knock on wood and be greatful I haven’t.

Vicki May 15, 2013 at 10:30 am

Very helpful article. It’s almost time for me to make another batch of detergent. I think I’ll tinker with the recipe some more. With my last batch, I switched from Fels Naptha to Ivory, and now I’d love to ditch the Borax. I am going to look for some Zote, also. Thanks for all your research.

Deanna May 16, 2013 at 10:15 am

I really found this post helpful when I was figuring out how to make my own laundry detergent and linked to it when I made my own post. So thank you for sharing!

Teresa Kwon May 21, 2013 at 2:58 pm

To clarify…
When you said, “… 3T in the washer, 1/2 cup vinegar in the rinse. For lights and whites, I use hot water, 1/2 cup peroxide in the bleach compartment..” Do you add the peroxide with the 3T (of your homemade laundry soap) + 1/2 c vinegar or does the peroxide replace something?

And do you have any thoughts on soda ash (for example: look below), not Arm & Hammer washing soda? If I understand correctly, soda ash is the pure or more purer form of washing soda, sodium carbonate Na2CO3?


Cissy May 31, 2013 at 10:54 am

Sommer, I just made my detergent and was wondering what amount do you use for each load? I was told to use 1Tbsp?

Brian May 31, 2013 at 11:56 am

I use about 1.5 tablespoons, but I also think it depends on the hardness of your water and how dirty the clothes are.

I use a scoop that came from a jar of “dollar store Oxi-Clean”. According to my kitchen measuring spoons, a rounded scoop of laundry detergent using that scoop measures approximately 1.5 tablespoons. If I am washing more soiled clothes, then I will usually throw in another half scoop. Hope that bit of information helps.


Kristie June 21, 2013 at 11:45 am

Is the Ivory soap non toxic? (I am really careful about that kind of stuff because of previous health issues.) Would the ivory soap, washing soda and then vinegar work for hard water and sweaty clothes?

Abbie June 25, 2013 at 8:06 pm

So I wanted to add enzymes to my detergent mix but I could not find one at my local store so I got Papain in the meat tenderizer isle. Can I use that for now till I get some off the web?

Ivory Soap June 28, 2013 at 8:02 am

I would think so.

Laurie July 24, 2013 at 8:23 pm

Regarding borax ruining clothes, I haven’t had that experience. However, I use an old washing machine with cold water and only one rinse, and I was tired of the borax powder not rinsing off properly. Solution: While the washer is filling, mix half a cup of borax with a quart of boiling water from the kettle, stir well and wait a minute or two until completely dissolved), and add to the washer when it’s full of water.
Actually, now I do the above with borax and soda ash (aka sodium carbonate, or pool chemical for raising pH); I only use 1/4 cup of this mix (again, with boiling water), and it works better than borax alone.
Oh–you have to put vinegar in the rinse or the crystals from the borax and/or soda ash will crystalize on the clothes; maybe that’s what ruined yours. Some say don’t use vinegar in a washing machine, or that borax is not environmentally safe, but we all have to look into these ideas and decide for ourselves.

Mary August 31, 2013 at 10:20 am

I have been making laundry detergent for a couple of months now. I have noticed a mildew smell on and off on some clean articles of clothing. I never notice the smell after getting the clothing out of the dryer. I notice when I grab the item from the drawer. It didn’t start until I started using my own concoction (Borax, Washing Soda, Dawn dishwashing detergent. I like the low cost and would like to continue. Any suggestions?

Kay Mahoney September 18, 2013 at 12:28 pm

Ditch the borax entirely. Also, are you doing liquid or powder? Liquid loses power over time. Powder is more stable.

Cindy A October 17, 2013 at 10:13 pm

Thank god for the perfectionists out there, doing all this good research! Saved me from having to do it, and I’m busy, organizing my sock drawer by color, type, and season…

Jenny D October 18, 2013 at 9:31 am

What type of washer are you using when you use 3T of laundry detergent?

Desert Fox October 26, 2013 at 12:33 pm

If you want to bleach the natural way…just soap the item and place it in the sun for a bit. It works!

When you say “Liquid loses power over time” – if you wash regularly, the liquid will be used within a decent period not becoming weak! The powder kind of soap might not dissolve well if you pile it in one spot. You might want to dissolve it in a cup first to distribute it better in the liquid stage. Ah!… a little bit here and a little bit there! Life is a blast!

Ivory Soap October 28, 2013 at 6:44 am

top loader, jenny. You need less for a front loader

Randell December 22, 2013 at 5:51 pm

are effectiv? for weight control as long as they are not taken without any sugar oor cream.

What w? do need tto know is very simple:
Drinking tea will help us lose weight.

David Custer January 11, 2014 at 8:53 pm

After reading your research. I tried the following recipe. Which works for laundry powder, dishwasher detergent, and scouring powder.

1 cup washing soda
1 cup 100% coconut oil soap with 1% super fat
1/4 cup citric acid
1/2 cup sea salt

Thank you for everything!

janet January 21, 2014 at 5:20 pm

Thanks for doing all this research! I have shared this page many times. For all the people who ask if it works in well water…the answer depends on where your well is, or in other words what kind of water you have. I have used it with well water and had great results. My water has lots of iron in it but apparently not much calcium and/or magnesium which makes water hard. You really just have to experiment to see what works best in your particular water.

Teri January 27, 2014 at 4:56 pm

So could you tell me about how much Ivory soap and how much washing soda you use? Maybe I missed it. Thanks!

Teri January 27, 2014 at 5:31 pm

Also, is it safe for HE toploaders?

dena February 12, 2014 at 3:45 pm

I am so overwhelmed with all this information I don’t know what to do. I currently make my own liquid detergent, washing soda, borax and some kind of soap. Sometimes I will add a TSP of salt to the load for fading. Ive got a top loader and have not had any issues. Upon reading this info I don’t know what to do, someone please help me.

kim February 16, 2014 at 11:46 pm

Hello, thanks so much for the tips. I just wanted to let you know that you should probably stay away from the bacteria b. cereus if you have kids in the house. It can cause a nasty stomach infection, it is one of the bacteria that causes food poisoning! http://www.foodsafety.gov/poisoning/causes/bacteriaviruses/bcereus/

Rebecca March 20, 2014 at 4:02 pm

Do you have any thoughts on using the liquid enzyme cleaner meant for pools as a laundry additive? The instructions call for 8 oz. per 10,000 gallons (!) so I was thinking a few drops in each load of laundry, but I’m too chicken to just try it without some input from someone who understands these things.

Alicia July 28, 2014 at 7:05 am

OK. I’ve tried the recipe Ivory Soap uses and while I love it, it doesn’t seem like it lasts a long time. I think my batch (using a single bar of soap and equal parts of washing soda) only lasted a week. Am I doing something wrong? I have a family of 5. I used to use the recipe that called for lots of water, washing soda, borax, and a bar of soap, which lasted half a year for my family (but it didn’t clean as well as I’d like). However, it doesn’t sound very cost saving if a bar of soap will only last a single week. I feel like I have no choice, but to go back to Tide.

Abraham Girt August 14, 2014 at 1:50 pm

Thank you so much for these tips. (I didn’t know them).

Paige September 2, 2014 at 4:05 am

I’ve been making my own laundry soap for years. I only use washing soda, ivory soap and borax. The only variation I’ve used over the years is if I use water in it to make liquid or not, either way works the same for my laundry. I’ve used this formula on cloth diapers, cloth sanitary pads, regular every day clothes and since my family and I rely on second hand clothes, this formula cannot be beat. Everything is and smells clean, every time. You only need a tiny bit, one or two tablespoons, and a nearly perfect load of laundry every time. My washer is wonky so it only washes in hot water, not a big deal for my family, though. Like I said, I wash cloth diapers, etc. If you want your soap to last longer, use one bar of ivory soap with two cups each borax and washing soda. You’re laundry soap will last much longer and your clothes will be just as clean.

cp October 24, 2014 at 1:17 pm

There is one property of borax that you’re overlooking. It is an anti-fungal and great against mildew. I live in a mildew prone area and I definitely add it to my detergent. Especially if I’m using soap (which I don’t usually). Soap can leave build-up (soap scum) behind and mildew likes to grow on soap scum. My mom’s front loader is particularly prone to mildew and she does a rinse with borax and without clothes to remove the mildew.

Mimi December 2, 2014 at 3:58 pm

I don’t grate my soap anymore–so much easier to just soak it.

When I make a batch of soap, I drop a bar of soap into a cleaned, plastic Folger’s coffee canister, fill it 3/4 of the way with warm water, put the lid on, and stick it under the bathroom sink.

By the time I need to make another batch, it has long since turned into slimy soap-water, and is so easy to mix in! Obviously, for my first batch, I planned ahead (so unlike me, lol) and soaked it a few weeks before making my first batch of laundry detergent.

BTW, a lot of people talk as if all the soaps are interchangeable for the Fels Naphtha. They don’t realize that Fels Naphtha is NOT a bar of soap–it is a laundry stain stick in the shape of a bar of soap (for easy rubbing over large stains). I’m not saying bath soap doesn’t work–I’ve never tried it, but plenty of people have–but you are losing some of the cleaning power of the original recipe if you don’t use Fels Naphtha, which specifically powers up the batch for stain removal & heavier cleaning.

What about septic tanks? No one has mentioned what these soap build up does to them. I made some laundry soap, fels napa , borax, and washing soda, with oxi clean. 9 months later we are having odor problems with our septic……I hope I have not cost us a new leach line in trying to save money on laundry soap! Not a good bargain in the long run. Someone told my husband that powdered soap is bad for septics.

Loren Amelang January 14, 2015 at 9:25 pm

Re: Septic Systems…

I don’t have a scientific answer, and septic tanks are so varied in construction, other loading, and leach field soil, it probably isn’t possible to provide one. But as one data point, I’ve used my washing soda, borax, and New Age (liquid detergent) mix for over 25 years on the same septic system with no problem whatsoever. I’d be much more concerned about putting chlorine bleach or antibacterial products (including excreted antibiotics) into the system.

If you are at all concerned, I’d suggest regularly adding a bacterial product made for septic tank support. I’ve used the Canadian “Septonic” brand forever, it is much more economical than the US competition. Does it work? I’ve never had occasion to open my tank to see…

Lizzy Bee January 24, 2015 at 5:57 pm

THANK YOU for this post! I am a DIY laundry detergent maker and I firmly believe LESS is MORE when it comes to ingredients. My go-to recipe is always borax, washing soda, and a grated soap (Fels, Zote, Castille, etc.). I have come across quite a few “recipes” on Pinterest that are not only ridiculous, but completely self-defeating.

It seems like some people literally just go to the store and buy every single item they see in the laundry aisle, bring it home, throw it all into a food processor, grater, or bucket, and write an article claiming their concoction is “the best ever DIY laundry detergent recipe.”

To me, that’s like buying every type of disinfectant, floor polish, scouring scrub, and window cleaner, dumping it all together, pouring it into empty spray bottles, and then writing a blog post about my “amazing all-in-one house cleaner.”

Anyways, thank you for such an informative post. I shared it via Pinterest and hope that the many detergent do-it-yourselfers out there will read it, too!

Lori January 30, 2015 at 2:56 am

Just want to draw your attention to the fact that the bacteria B. Cereus is a pathogen. see http://www.foodsafety.gov/poisoning/causes/bacteriaviruses/bcereus/ , however the first one you mentioned is not toxic. http://www.epa.gov/biotech_rule/pubs/fra/fra009.html

Are you not concerned about the impact of using a toxic bacteria in your laundry detergent? Could it be harmful if it remains on the clothing?

Just a little worried about this.

Kind regards

Daisy January 30, 2015 at 6:03 pm

Lori–The “ingredients” Deanna mentions in this post are found in commercial laundry detergent. And she was really just kidding about making your own bacteria. We’re crunchy but we’re not THAT crunchy!

Jenn February 17, 2015 at 9:17 am

Thanks for the great info – it was super helpful! Be careful of the B. cereus – it’s the bacteria in spoiled fried rice that causes severe food poisoning that we see people in the hospital for.
