Okay, I did another rainwater laundry wash this past Saturday. I had the 60 gallons I needed for it. Used the portable pump to fill bucket-bucket-washer.
Used the Soap Nuts. This time, I used one bag of the nuts....versus the 2 from the first time. Added the splash of vinegar to the wash. Nothing else. I was not too impressed this time with this wash. Last time, using the 2 bags of nuts..12 soapnuts....and a squirt of Dawn dishsoap, things worked really well. This time, just the 1 bag of 6 nuts..nothing else...I don't feel it did enough for breaking down work and body soils in the fabric fibres. DH is a machinist, so he gets pretty dirty. My stuff, is just dirt and grunge from around here.
I already know I won't be using the soaputs for washing towels/washcloths. Those need the bleach, detergents and hot water..to sanitize them. I cannot stand a nasty smelling washcloth. I don't care if they are stained a bit..I have about 100 white washcloths..and wash when I run out. I just use the fresh ones, let them dry, toss them in the hamper I keep for them, then wash when I get down to 10. If they get too worn out, they go to the rag bag. I have about 50 white rags I wash. Learned both of these when I was working at super8 as a maid/deep cleaning person.
Anyhoo...soapnuts and rainwater are working good enough for regular sheets, daily wear clothing. I think I will just be adding the squirt of Dawn to the really dirty stuff. Soapnuts work well otherwise. I am also keeping track of how many uses I get from them total.
