Promising review:"After using this product, I am happy to report that my $5 investment saved me over $500. I was ready to replace my dishwasher due to super cloudy glasses, residue, and just not getting clean. Then, I became aware that the water softener no longer was doing its job, so I had the rental company replace it. Dishwasher performance improved somewhat. I decided to do two more loads before deciding to purchase a new one. Then I saw a product test review for Affresh in a magazine. I was ordering some stuff from Amazon anyway, so I added that to my order. When it came, I tossed one of the tablets into the bottom of the full machine, and ran the regular cycle. I did not expect the results I got! My glassware that I thought was permanently etched and ruined came out like new. Same with cutlery. The difference is unbelievable. I will use this faithfully on a monthly basis, as recommended. I can even put it on my subscribe and save order, so I will get a new pack every six months. I am amazed!" —Sheila
