In addition to the above tips, you might want to make sure your mold is sparkling clean to begin with too. I just pour boiling hot water into my molds then wipe with a paper towel to clean off excess wax gunk. Some folks put molds in a hot oven with a drip tray underneath to catch wax, then wipe w/ paper towels to clean. Use potholders -- ack, the molds get hot!! There may be some wax build-up inside your molds that may be causing the candles to not release all smooth and shiny. HTH :-)
