I recently purchased from Sainsburys a device called "protector" from
Finish.

It is a little plastic device that clips inside the dishwasher.
Apparently, it realises something into each wash that is designed to
protect glasses from going hazy.

It says on the box: "use detergent, rinse agent and salt or 3in1
product as usual (Salt not available in Australia or New Zealand)"

I gather from a previous thread that in Australia they are having
problems with the levels of salt in water.

Yup:
