Note: I originally wrote this over two years ago on a previous blog, and I haven't purchased storebought laundry detergent since. It makes me very happy to think about how much money I've saved, and to know I am not tossing tons of chemicals into our local water supply. So, I'm sharing it again, here.
I have found that I enjoy a bit of scent in my laundered clothes, and I solve that by using woolen dryer balls (rather than disposable dryer sheets), and putting a drop or two of lavender or rosemary essential oil on them before tossing them into the dryer.

It's a goal of mine to make an exercise of trying as many methods as I
can of reducing costs, reducing my environmental impact, cutting out
unnecessary chemicals from my life - and household products are the most
direct way I can think of to do this.
So today, I made laundry soap - I won't know until tomorrow when I run a
load with it whether or not it works satisfactorily, but here's what I
know at this point - the total cost of supplies for this would have run
me approximately $3.00 (while overall, it cost more than that, you'll
see that a large quantity of detergent takes only a fraction of the
supplies... if this works, I've got enough to keep me supplied for
months).
So the savings is undeniable - if this gets my clothing clean, I'm way ahead of the game.
So what about the other reasons?
First,
environmental impact - I am told this formula is low suds... there is
some sudsing, but not too much, and of course it is missing all the
stabilizers and scents and binding agents intended mainly to make the
degergent look smooth and rich coming out of the bottle. All of that
ends up in our water supply. And I know from some work done on the
pipes here a couple years ago that commercial products have suds so
strong that they stay in the pipes for days after they've been flushed
through the system - at the plumber's recommendation then, I switched to
Arm & Hammer detergent, and it's done me fine. Now I'm taking that
one step further.
Secondly, chemicals - that is one thing I'm looking to see - we've got
Borax, A&H Washing Soda, and the Fels-Naptha soap (which, to be
frank, did smell and feel mildly caustic - I am wondering if Ivory might
be a better answer, and if it would work as well?). So this part is an
open question for me, but without a doubt, there is less going on here
than there is with any commercial product.
The time start to finish to prepare this was about 25 minutes - no major
issue to spend that much time once a month or so. Here's how I did it:
Homemade Laundry Detergent
1/3 bar Fels-Naptha soap
1/2 cup Borax
1/2 cup washing soda
1.
Begin heating 4 cups of water to a boil. While the water heats, grate
the 1/3 bar of Fels-Naptha soap using a box grater into small flakes.
Be sure to wash hands well after grating... this is a mildly irritating
soap.
2.
Once the water boils, begin sprinkling in the grated soap, a couple
tablespoonfuls at a time. Stir constantly - it will begin to suds up
and will overboil if not stirred. Work slowly so that soap dissolves
completely.
3.
Once all the soap flakes have dissolved, lower heat and add 1/2 cup
each Borax and washing soda, continuing to stir until completely
dissolved. Remove from heat.
4. In a very large container (like a clean bucket), pour in 4 cups of
very hot water, then add the soap mixture. Stir, and add an addition
gallon plus 6 cups of water and mix well.
Now... this is where I messed up - I had a container I thought would be
big enough to use and it quickly became clear it wasn't, by half. The
only container I did have available to me (my bucket not being clean
enough to use) was my large stainless sauce pot. So here's hoping my
metal pot isn't ruining the soap - or that the soap isn't ruining my
pot. Oi. I'll turn the soap out into a couple smaller containers
tomorrow and find out.
5.
Last step - set the container aside and let it rest for 24 hours - I'm
told that it will gel up to some degree or another - anywhere from a
full gel to watery with gel floaters, but either way, it will be ready
to use.
The proportions for using this are 1/2 cup of detergent for a load of
laundry. I'll take a final picture tomorrow afternoon to show what it
looks like after setting up, and then do a test load of laundry.
Oh
- as a nice final bit of frugality - the supplies (other than the
Borax, which I already had) didn't cost me a penny, because I was able
to purchase them with giftcards I'd acquired from using Swagbucks.
Considering that laundry detergent has been a budget buster for me in
the past, I'm pretty tickled that it may be something entirely free for
me for the next few months.

UPDATE:
The first thing I did after waking up this morning was to head into the
laundry room and take a peek. Happy dance - I've got gel! It's about
the thickness of jelly, rather than gelatin, and was firmer at the top
of my pot than down toward the bottom - but it thickened all the way
through, and it was an easy few minutes work to turn it into a pair of
plastic containers. The total amount looks to be a little more than
double that of my commercial jug of detergent and the amount to be used
is pretty close to the same.
I've run a couple loads of laundry and can't tell any difference at all,
other than a lack of scent... which really isn't a bad thing, although I
may toss in a little essential oil in a cheery scent whenever it's time
to make my next batch, just because I can.
And yes - barring finding out something that isn't apparent yet - I'll
be continuing this project and happily saving the $20.00 dollars a month
I spend on laundry detergent.
