We had a irridescent film on all the glassware. It scrubbed off by hand with a scouring pad but the dishwasher just put it back on.

I wasn't using salt, though, just the baking soda and borax. I've started doing 1 c. borax, 1 c. soda, and 1 c. Ecover dishwashing powder. It works beautifully. No more film, sparkling dishes, easy to make and easy on the checkbook.

Are you using a rinse-aid as well? Plain old vinegar in the rinse-well of the dishwasher is what I sometimes do.

If your water is medium- to very-hard you may need to either use more powder in the dispenser or add more salt or citric acid to the mix to soften the water. Citric acid, aka, sodium citrate, is among many other things, a water conditioner or softener.

If there's not a brew shop near you, you can get some in a pinch in the canning section of your grocery store. It's called "Fruit-Fresh(R)"--what you sprinkle on your apples to keep them from browning. It's mostly citric acid. That'll get you by for one batch or so until you can land a source. You can buy online at bulkfood.com or amazon.com, no less.

Keep trying, you'll hack it!
