Okay, I finally made myself a big bucket of laundry slime. I used a bar of Fels Naptha and this recipe. Although I goofed and put twice as much borax. But I figured it will just help soften the water and shouldn’t hurt anything.
The detergent makes absolutely no suds at all! I was concerned, even though I read in the posts that there would be less suds, I was worried. But the stuff cleaned Dennis’s couch blankets good! They no longer stink and are bright and clean.
