I made a laundry soap just recently. I'm also trying to reduce the amount of money we spend on cleaners, and use more natural cleaners so this is kind of fascinating for me. I have a big house, lots of little kids and this place is always dirty. Always lots of laundry piling up, cloth diapers, dishes and cleaning up to do so I get to make and try things out.
The laundry soap I am making uses borax, washing soda, Zote and tea tree oil/lavender. Lots of recipes out there but it's basically 1 bar of grated soap, melted in a pot of hot water, 1 cup borax and washing soda, 4 gallons hot water. Allow to sit over night in a pail and then mix together and add essential oils. About 20 of each. A cup of oxygen cleaner can be used in this as well but I prefer to add that separately. I think it's important to note that this is a "soap" recipe and in some water conditions may leave a residue in clothes, so extra rinsing and maybe some vinegar might need to be used once and a while. I do not use this on towels or cloth diapers.
This is what I use on them. 1 part borax, 1 part washing soda, 1/4 cup epsom salt or kosher salt, 1 part oxiclean and 20 drops tea tree oil, and (optional) 1 T blue dawn dish soap. This is for cutting grease. Mix all the powders together in a bowl and make sure there are no lumps. Add the tea tree oil and the dawn and a couple drops of Mrs Stewarts Laundry bluing. Mix this all very thoroughly together and store in a container. Use up to a 1/4 cup on a load depending on size.
I made some dryer balls recently too and am using them for the first time today. But when I was researching stripping cloth diapers someone made a note that the dryer will have residue from dryer sheets so I had to wash out the dryer today with dawn and try and make sure that the residue was out of there. I wanted to make sure that that was done before we started using the dryer balls. Glad I did that actually because it was filthy. So gross.
Tomorrow we are getting a new washer because my old one is so much trouble. The drum liner started rubbing funny and scraping and has rubbed all away at the top, and then it stated leaking and no longer spins out all the way. Wish I could have gotten a new dryer as well but it is so expensive! Anyway a new washer will speed things up so much and get the clothes cleaner so I'm happy.
I'm still looking for a good all purpose cleaner I can put in a spray bottle.
