It seems no matter what dishwasher soap or rinse aid I use, we ALWAYS have those icky water spots/residue on our dishes. I have finally learned what works (for me, at least) to keep them away. I let the dishwasher run its full cycle. As soon as the last rinse has gone by, I go back and turn the dishwasher to rinse again. If I rinse twice, we have no spots! YAY!
This is nice because I was constantly changing dishwasher soaps and rinse aids. Although, last week I did get a coupon book in the mail from Home Made Simple that had a coupon for a free Cascade Crystal Clear Rinse Aid. That was nice - it saved me $3.19.
