I was wondering how long you should feel the zap on cp soap? evidently, my 13 yo and her girlfriend spent the weekend licking my soaps!!! (she just told it tonight at dinner) she said they sting....so of course I had to try and she is right. the soap is about 3 weeks old (i thought that it would be gone by now). Also, I have just tried crockpot soap for the first time last night and it has a little sting!! I thought I was doing it right? soap looks ok, the bars are hard. just not sure what I did or did not do.
