Why is there such a big online presence of the zap test for pH? That is so much more dangerous (i.e. regular burns, lye burns)! Am I the only non-crockpot HP soaper who uses Phenolphthalein (pH indicator)? I've had the same bottle for years, and it's so easy to use!
I used to do this type of shred and heat recipe. Now, I leave out the grated bar of soap. I've gotten out all kinds of things with the small amount of washing mix I use. My hubby recently did laundry for me and didn't know about a (chocolate) spot on my sweater that needed to come out; it still came out. I've also used Zote. I like this blend the best: https://www.youtube.com/watch?v=4l-VywF8vg4
