Product review (5 stars): Huzzah!  Calcium deposits and streaks FIXED with PowerHouse
I was about to get rid of my old dishwasher because I couldn't stand the calcium deposits and streaks on all of my dishes, but especially the glass and stainless steel.  And then my daughter purchased this from a dollar store, and when I started putting away dishes one night after we'd used it...I was STUNNED.  The glasses were squeaky clean--no white streaks or splotches.  The utensils and cutlery and pots and pans were glistening, for the first time in ages.  I don't know what's in this stuff, but I don't have to use vinegar or any of the commercial "dishwasher refreshers" on the market.  It took care of the deposits that were gunking up my dishwasher and dishes, and I am absolutely astounded at the difference it has made.  Now, I don't have to wipe off or rewash everything before I put them on the shelves.  This stuff is amazing!
