What a dud!
We used these to wash our clothes, however, they did not foam in hard water or water from mineral springs.  They did not adequately take out odor, either from clothes.  We used several strips in a basin with no effect.  We eventually had to buy liquid detergent when we settled in Bulgaria for a week.  Next time, we plan to take packets of liquid detergent, instead.
