Firstly, I've tried Googling but without definitive results.
Since we had the water softener installed I've noticed that the (probably) aluminium rivets in some kitchen knife handles seem to be slowly dissolving. However the knives are about 8 years old so this could be cumulative.
There is also discolouration on some rubber knife handles.
Glass seems to be etching a bit more although we switched to a dish washer powder - Finish Classic powder - that Which? recommends as best for not etching glass.
The water is certainly very soft.
So, before I start extensive tinkering has anyone else seen similar results after changing to a water softener?
There is no salt in the dish washer salt container, so there should be no extra softening attempted by the dishwasher.
The dishwasher is new - part of a Howdens kitchen and their own brand - so the change in dishwasher could also be a factor (although I am not sure how). New dishwasher and the water softener installed at the same time.
