Pat:
What kind of bar soap do you use
We use Dove, Irish Spring and a melt and pour goat's milk bar. The goat's milk bars are the ones I used most often but we have run out. I decided to try a glycerine bar from the store for the hand soap and cleaning recently instead of Dove or Irish Spring. I can't say I am pleased with the results.
One thing I didn't note earlier is that I always do a rinse mopping with clear water after mopping with the soap. This makes a difference.
