They do not leak any of the detergent in the Scotch Brite cleaner
I have used other dish wand refills that have small holes in them, and they always leak the detergent in them so that the detergent has to be replaced very often.  These refills do not have the holes in them, so they do a great job in helping to clean sinks, dishes, pots, and pans without leaking any detergent.
