Hi Heather,
Thanks for leaving your review here first of all.
I was a bit surprised by the content of it though, the Stainless Steel Shaker should be fine for in the dishwasher as well as the others, I do it myself always as well, no issues for 3 years using the same one now.
If there's something wrong with the shaker, feel free to check in with us for a replacement of that. You can check in through the Live Chat option on the website or by emailing love@jimmyjoy.com. We will gladly check that for you then.
