When I was first married many, many, many years ago, I had the same problem with my "Sculptured Daisy" dishes. I wrote the company (no internet then) and they told me I could remove it by rinsing them in mild bleach water before washing them. Yeah, right -- I'm sure going to do that! I just ignored it, got some cheap dishes for guests, and used those Daisy dishes for over 25 years!
I agree about the Fiesta. When I need new dishes, I plan to get them. I love all the colors. Right now, we use our Corelle for everyday. And we have Pfaltzgraf Jamberry also. Have Winterberry for Christmas. Also have the Pfaltzgraf solid color stoneware (can't remember the name); and they chip so bad we can't use them any more. Just washing in the dishwasher chips them.
Probably more info than you needed; but for the most part (2 out of 3), I like my Pfaltzgraf.
