My homemade laundry detergent recipe completely changed after hours of research on this household chemical database!

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.  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 your dry homemade laundry detergent 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 more washing soda in your homemade laundry detergent.

3.  NO detergents contain BAKING SODA

Not even Arm and Hammer.  Baking soda is only half as strong as washing soda for 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. 

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.

Conclusion:  It’s hard to get out many stains without an enzyme cleaner.  Buy one. (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!)

Now, Let’s Talk Whites

6. ONLY powdered commercial detergents use Oxiclean. 

Oxiclean becomes peroxide and washing soda once it hits liquid.  Any liquid detergent claiming to contain Oxiclean likely has peroxide in it. You can make your own Oxiclean POWDER by mixing peroxide and washing soda and dehydrating it, but there’s really no point.  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. (Home liquid versions lose their poop ~month.) 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. My water hardness is about 17.5ppm.  For my 40 gal top loader, I need 2 cups of store bought vinegar to do the job.

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.  And, I’m not entirely sure that it’s not just there to make the tablets hard.  Citric acid makes great tablets.

Conclusion:  Don’t put it in your homemade laundry detergent unless you have REALLY bad deposits that have to stay suspended the whole time; use the rinse compartment instead.

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