Best bar soap for hard water?
I live in a hard-water region. I'm in an apartment complex so there's no opportunity for me to have a water softener installed.
My question is, what bar soaps will lather well and not leave curd in the tub, even in a hard-water region? I'd be willing to buy either real bar soap, or an artificial 'beauty bar'. I'm not interested in switching to shower gel.
So far, I've found that Clearly Natural soap leaves the tub clean, but doesn't lather. Aveeno Moisturizing bar lathers and leaves the tub clean, but it's an exfoliant, which I'd rather not use every day.
I've tried guessing whether or not a given soap will work well in hard water, by reading the ingredient list, but I haven't been very successful. Please recommend specific products if you can.
