I started making laundry detergent using 1/3 of a bar of Dr Bronners, 1/4 cup borax and 1/4 cup of washing soda with 1 gal of water. We have an old top loader. I typically start the water, dump in the soap (about a capful from a detergent bottle, maybe 1/4 or 1/3 cup of detergent) then add the laundry. I'm having issues with the soap occasionally leaving greasy looking spots on clothes. I originally thought it was because I had been using glycerin soap so switched to the Dr Bronners but am still having this problem. If I use more soap in the wash then the soap doesn't all rinse out. Any ideas?
troubleshooting homemade laundry detergent
I don't know how much Dr. Bronners superfats their bars so maybe that's the issue?
Have you tried using part of a Fels Naptha bar? You can find those in some grocery stores in the laundry isle.
Also, I'd try upping the Borax and Washing Soda.
Also, I have an old top loader and the instructions on the lid say to add detergent first, then clothes, but I find with homemade laundry soap it works better if you put the clothes in while the it's filling up and then drizzle the soap on top. Seems that the action of the washing machine works best when the soap is working it's way down through the clothes.
I've been using homemade laundry soap for 7 years and haven't had that issue, so I'm just guessing!
I avoided using Fels Naptha because of the ingredients. I'll see if a little extra borax and washing soda helps, though it seems like our clothes are getting pretty faded. When I add the soap after the laundry, it seems like the greasy looking spots are worse. I'm too lazy to wait around for when my washer is rinsing to add vinegar to the rinse cycle though haha. Thanks y'all.
