Black spots on Stainless Steel cutlery and pans?
I have recently been getting black water marks on all my stainless steel. I have been thinking maybe it was because I used a different brand of DW tabs- I used Ecover instead of Finish. I went back to Finish- but the marks remain. I thouth the culprit could be that I use vinegar in the rinse aid of the DW. (even though I have been doing this for years, no black marks) So I hand washed the stainless and dried it by hand to get rid of the marks. Then, this morning I noticed husband had kindly hand washed all the stainless and left it to air dry- the black marks are there! So it isn't the DW or the DW detergent- but it must be something about my water? This has only started happening recently. It is driving me crazy. Th only way to get rid of the large amount and very noticeable black marks seems to be to hand dry all the stainless. ( I have noticed that the glass ware is also coming out spotty, too. But not black. )Any ideas what can be causing it?I do live in OK and have hard water- but like I said- this is a new thing. Should I add some borax or baking soda to the load? I used that DW cleaner stuff last month so I know the machine is clean- and it was recently serviced. I'm stumped.
