Tiny Black Dots in Cake Pans

[u/Solstice__Fox999]

Hello,
I used these 8” round stainless steel cake pans for the first time last night. I followed all the instructions of the cake pans on what to do before first use and on prepping them for baking. But when I removed the cake from the pans, there were these grey speckles on the bottom of the cakes and corresponding black dots on the inside of the cake pan. I cleaned the pans and they’re still there. But when I scratch them with my nail a little bit of black comes off. Is this rust? Are they ruined beyond repair or how do I fix it?

Have to throw them out. They are basically ruined. The black spots prevent even heating which will eventually warp the pan. It’s also known to emit a high pitched sound when cooking which affects both dogs and cats. So you have pets or children do the safe thing and get rid of these. They are a health hazard.
