I DIY my powdered laundry detergent, usually with Fels Naptha bar soap. However, I couldn't find it locally when I looked recently, but found pink Zote instead. Bought a few bars, then started Googling, and I'm concerned it won't dissolve in cold water? And/or won't clean as well as the Fels Naptha? I don't want to make a huge batch only to hate it and wish I had've just ordered the Fels Naptha!

This is probably a long-shot, but anybody use Zote? Does it do a good job of cleaning? Does it dissolve in cold water?
