Every color of the Rainbow Cupcake Liners stained my pans. They also made the muffins taste odd.
Bought a package just under a month ago and I love having all the different colour choices in one package. I have used them for a birthday party and 2
baby showers and St.. Patrick's day !
Just bought these today and used them tonight- they stained my baking pan! I can't get the color off the bottom of each muffin cup. When I looked at the package more carefully I noticed a strong smell like paint. It makes me wonder what is being used for the dye on these cups!
Bought a smaller package of these a few days ago, and used them immediately. The pink ones left a permanent stain on my cupcake tins! The yellow and blue ones did no such thing, and I haven't used any of the others - so I assume just the pink is the issue.
As other reviewers, I also had the purple liners stain my muffin pan. I do not recommend them for this reason.
