Hi, this website is amazing- did not see a similar post so here goes,

I have Reed & Barton matte finish (with bright accents)stainless steel 18/8 everyday flatware. I have been noticing what I think are hard water spots on the matte portion of the flatware for about 3 months now and we have been in this rental home (while new home being built)for 5 months- never had a problem in last home (were in for 5 years).

We use liquid cacade complete dish det (always have) and I recently bought rinse-aid (never have used, just a thought I had), but it does not help these spots.

Any advice? The spots can be kind of rubbed off with a kitchen towel but come back after next cycle. BTW the DW is kitchenaid and washes dishes nicely- no food left at all with only minimum pre-rinsing...
