ok, I need to know.....how do you keep your cupcake liners looking pretty and not all brown and ugly?? Is this a dumb question?? Should I know this??? 
i have to admit, i have never had brown and ugly liners is it the top? the bottom? all over?
oh, do you ever use your muffin pan without liners? the leftover oil, grease,etc could be getting on your liners. other than that, i am not sure why that would be happening.
Ohh, I know this one! Same thing happened to me until I started buying grease-proof liners. The oil, moisture, from the batter is seeping through the paper. Its especially problematic with boxed mixes, which tend to have chemicaly oily batters.
I just placed an order from this website and got some really inexpensive grease proof liners.

the site has a $50 min. order (I had been making a list of all the cake stuff I wanted for a while) but they have really cheap supplies and shipping. If your only looking for liners, I'm sure there are some other sites out there
also what condition is your muffin pan that you use. if its old and seasoned (dark) this could be a problem. leaving marks on your papers.
Thanks for all the help!!! I think the last time baked cupcakes I was using box mixes. I have graduated to scratch cakes because there really is a big difference!!! Once you start from scratch you can never go back!!! lol
I will buy a brand new pan and stick to my recipes and see how it goes! Thanks again CC people!!! You came through as usual!!!
