Finish GelPacs are the best. I have a 23yr old GE dishwasher and everything comes out clean, spotless and shining.

That is because your dishwasher is 23 years old. If I had held onto that model I would be a happy woman today.
Unfortuantly I upgraded and it was to a terrible world. There must be a heaven for good old appliances.
I use gell-packs, but mine are generic versions of “Cascade” or “Finish”! You can get them at Kroger’s or (Smith’s) here in UT. You can get a pack of 20 for at the most $3.00, or less when it’s on sale. As you said, dishes and glasses turn out clean and shining! The gell-packs have a rinse agent in them. Since I started using them, they’ve been wonderful and don’t cost as much as the name brand!
