Softener salt?

At least here they sell some DW salt that is to be used in hard water areas... Newer dishwashers even come with a dispenser that is filled with fresh water before the maiden wash, and these salt pellets are then added when necessary and the dispenser is adjusted according to the hardness reading. I've been called on some cases where dishes have remained dirty, and 7 times out of 10 it has been solved by adding the salt. I don't know what it is, but it does make the water softer.

They tell not to use normal NaCl in the manuals, but the stuff tastes the same, and usually if I'm called on such a case, and the DW has the salt dispenser, I dip my finger in the tank and take a lick to find out. Often it's been plain water there, and as said, adding the salt has helped many. In cases with no dispenser, I have crushed half a pellet into the detergent dispenser, and it works the same way.

I have noticed that when handwashing dishes, adding normal salt (NaCl) to the water will break down the foam but it gives better washing results. Perhaps the DW salt does the same, but our DW detergents give very little foam anyway... Also the amount and type of detergent does count. Liquified detergents often leave some slime behind, the powdered concentrate doesn't.

I've noticed the same with hand soap. Most liquid handsoaps end up leaving more gookus into the sink and sewer pipes than conventional hard soap. And, mostly they really don't clean your hands as well. Perhaps this is because sodium laureth olamine (in liquid "soap") adheres with the plastic tubing as well as with grease, but sodium palmitate and stearate (real soap) doesn't do that as much.

I don't know if it's been wise to taste the DW salt, but I still have three eyes and a tail, so I think it hasn't affected me so far. If anyone has info on this salt, like what it is, and how on earth adding more minerals will make the water softer (but it does), I would be glad to know.
