1. .... is it actually possible to use
just the grated laundry soap (no borax, washing soda, etc.) in the top-loading washing machine -- has anyone used it, and what was your experience? And I guess I need to use vinegar in the last rinse?
2. Doesn't washing soda make coloured clothes dull? (That's why I'm trying to eliminate it.)
3. I saw a post at
http://butterbeliever.com/homemade-laundry-detergent-soap-diy/, which is in
complete opposition to what is being discussed in these threads. It has me all confused! Where does the truth lie?
1) Sure! I make a gift batch of stain sticks (heavy on the coconut and tallow) every year. In a pinch, you can (and we all have) grated it right into the washing machine. The washing soda is there as a water softener and to raise the pH of the water so the soap can work better, but if your water is soft, it's absolutely unnecessary.
I always use vinegar in water (3:28 ratio to make a full quart at a time) as a final rinse. I like the scent, the washer cleansing, and the anti-static.
2) Not that I've ever noticed, and I've been using my own laundry soap for years. I did shift the ratios, though: 3 part soap, 2 parts washing soda, 1 part borax. My water is very soft. Still, that would be enough to dull colors over time and it simply doesn't happen. One or two of my dress shirts still require batteries to operate.
Please note that one component she uses to get rid of all that icky "residue" is washing soda. All clothes have residue, and it might be wise to do that soak every once in a very great while if you want to get rid of it. I never bother.
3) She's selling laundry "soap" herself, from Young Living (I will restrain myself from making comments about the company, but go do the research). Please note the ingredients she touts:
Water -- useless, and usually in third or fourth place in our recipes by the time they fully cure. Or lower.
Decyl glucoside -- A weak surfactant, and also synthetic. That's fine, and it's quite safe (and used in baby shampoos!), but quite weak also limits its cleansing power.
Sodium oleate-- Olive oil soap, sort of. So much for not using soap in your washing machine, eh? It's a weak soap, too. This is a direct derivative of oleic acid rather than the sodium olivate (olive oil soap from whole olive oil) that we would make.
Glycerin-- We have that too, and it's not useful as a cleanser.
Below that, the ingredients are pretty insignificant, and fairly derivative of the above list.
I won't go into the chemistry argument she makes because I will get very, very angry if I do, and it's Thanksgiving Day. I have family to deal with later!
Happy Thanksgiving, and Soap On! And use your laundry soap in peace and certainty that it's just fine.
