I have not used them, but I have two friends who do use them for CD and their other clothes. both of them RAVE about them and say they're a must have. Neither of them has ever complained about buildup. The only complaint that one of my friends has is that you have to disolve them first for a front loader.
They are fine for cloth diapers! I'd been thinking of trying them, but don't want to have to dissolve them for my FL machine. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/greensad.gif" style="border:0px solid;" title="greensad">
